He introduced the gas into the many bottles he prepared to prepare ammonia, but although the ammonia was easily soluble in water, there would always be a large amount of ammonia leaking out between changing bottles, and the room was filled with the unpleasant smell of the latrine.

Ning was afraid that he would faint before he made sulfonamide, so he put on yesterday's gas mask, and at this moment there was a knock on the door:

"Yu'an, it's time to eat."

Ning Ji heard that the person at the door was Yan Yunzhou, but he couldn't speak at the moment, he looked at the bottles that were filled with ammonia, and immediately extinguished his homemade alcohol lamp, held his breath, and took off the mask on his face.

After he opened the door with both hands, he was facing Yan Yunzhou face to face, and his hand subconsciously pushed him, but he was afraid that he would fall, so he stopped him behind his waist with one hand.

Yan Yunzhou was taken a few steps back by his strength, and his hand was also wrapped around his waist, and there was only one big injustice left at the door, and the whole person was almost fainted by the smell of the pit.

Yan Yunzhou smiled and hugged the person in his arms:

"What are you doing here? Such a big smell? ”

Ning Ji reacted before he realized how ambiguous their posture was, and quickly let go of Yan Yunzhou:

"What else can I do? Get you some medicine. ”

Yan Yunzhou immediately thought of the allicin before Ning Qi, his medicine seemed to taste strange, this time the medicine wouldn't taste like this, right? He asked a very difficult question:

"Is this the same taste when you make it?"

Ning is a little funny:

"What do you think? If it tastes like this, what's the difference between eating? ”

Yan Yunzhou...

During the meal, Ning Qi heard Li Yan mention that the imperial court was going to summon Yan Yunzhou back to Beijing, and he hurriedly looked at the man:

"You can't go back to Beijing now, and if you go back to Beijing, the emperor may be going to kill you in many ways."

Yan Yunzhou sandwiched a piece of sauced beef for him, and he remembered that Ning Qi liked this:

"Well, naturally I can't go back, don't worry, I have a way to deal with it."

After the meal, several people went out, Ning Zhi naturally continued to go back to make medicine, Yan Yunzhou read the military newspaper in the room, Li Yan was going to the suburbs to see the people who had been resettled in Suizhou, Luo Yueli wanted to follow the past, but it was too cold today Li Yan was stunned and persuaded him.

In the afternoon, Yan Yunzhou wrote a letter to the guards of Baicheng, in which he instructed not to take the initiative to attack, that is, to consume with Beimu and the Qi clan, even if he went out of the city to face the battle, he didn't need to use all his strength, just a draw.

What he wants is for the court to think that they are in a stalemate with the Qiang people, so that the court does not dare to really make any moves against the northern army, and at this moment in the capital, the emperor is using the seal for the holy decree that summoned Yan Yunzhou back to Beijing.

Li Qicong began to feel uneasy when he knew that tens of thousands of people of the Qian tribe had been buried in Suizhou City, he was the emperor of Daliang, and he didn't even know such a big secret in Suizhou City.

"Eight hundred miles to send the holy decree to the north."

"Yes."

Li Qi sat back on the dragon chair, he looked at Wei Zhenhe, who was sitting down, and spoke:

"Wei Xiang thinks Yan Yunzhou will return to Beijing according to his orders?"

Wei Zhenhe's thin old face made the whole person's temperament even more gloomy:

"If he doesn't, he will be angry, and His Majesty still has to prepare early."

For the first time, Li Qi felt that the dragon chair under him was not stable at all:

"The soldiers of the Northwest Protectorate have been transferred to the edge of the northern border, when will the families of the several large battalion guards from here to the northern border arrive in Beijing?"

An official on one side immediately spoke:

"Back to Your Majesty, this time the Holy Decree summoned a total of eighteen generals' families, of which thirteen of the family members have set off, and three guards have never married, only some relatives of the side branches of the family are there, and the wives of the other two families are about to give birth, if they leave, they may be launched on the road, this morning the two generals stationed in the city have an excerpt and ask for the order to wait for the wife to give birth before entering Beijing to apologize."

Li Qi frowned, and glanced at the fold handed over by the official:

"It's really troublesome, what kind of child was born at this time?"

Naturally, the officials on one side did not dare to speak, and everyone knew that the emperor would not be able to blame the general's wife who was not in Beijing because he was about to give birth.

It has been seven years since he ascended the throne today, and the queen's birthday has never been big in previous years, but this year's war in the north took advantage of the queen's birthday to ask the family members of the guards who were still in the field to go to Beijing to congratulate, and he wanted to give the queen a big birthday.

This move has already been exhorted by some imperial history, and if the generals are blamed for this kind of thing, it may only cause more dissatisfaction among the generals and courtiers.

The few holy decrees in the past few days have made the atmosphere in the capital a little tense, and the war of words fought in the court in the past is likely to be a battle of arms at this moment.

The ministers of the DPRK and the Central Committee have not done anything else when they go back in the past few days, and they are almost all wondering whether Yan Yunzhou will return to Beijing this time, and whether it will really be reversed.

Su Beicheng went to see his old father today, and his face was still indignant:

"Dad, the emperor's move is really too bad, recruiting the general's family members into Beijing, this is clearly guarding against Yan Yunzhou, I heard that this morning the emperor has issued a holy decree to recruit Yan Yunzhou to return to Beijing, Yan Yunzhou's statement this time is directly related to the imperial court's attitude towards the north."

The old god of Master Su was there, and he lowered his head and took a sip of tea:

"Don't panic, don't panic, now it's just that Suizhou has repelled the Beimu and the Qian, Baicheng, and Xuancheng are still in a stalemate, as long as the foreign tribes are still in the north, even if Your Majesty wants to attack the north, the ministers will not agree.

As for Yan Yunzhou, his clever ghost would have thought of this, this time he would never return to Beijing, but as long as he did not get off the ground, even if he did not return to Beijing, he would save enough face for His Majesty and give an explanation to the ministers of the court. ”

Speaking of which, Master Su took another sip of tea:

"However, the family members in the Flame King's Mansion really have to prepare early, the beginning of next month is the birthday of the first emperor, and your sister will be ready to leave for the Yuelin Palace in the next two days.

The princess is a wife, the first flame king is buried in the emperor's mausoleum, and the princess walks with the queen mother, even the group of Wei dogs can't spew any dung. ”

After all, the princess is Yan Yunzhou's sister-in-law, not his wife, even if the person in the palace and the Wei family wants to use her to contain Yan Yunzhou, there is no reason at all, after all, Cheng Qingqian is a widow living at home, the Cheng family is a family Qingliu, and her husband died for the country.

Even if Yan Yunzhou really reversed, before that the Cheng family picked up their daughter or directly asked the queen mother to come forward to let the princess become a monk and practice, the palace would not be able to really kill everything.

Su Beicheng knew that his father, the old fox, could see it clearly, and he said quietly:

"Dad, how do you swear?"

Su Taishi blows his beard:

"What do you care about?"

In the afternoon, Ning was fighting against two things, that is, aniline and chlorine and sulfonic acid.

The raw materials needed to prepare sulfonamides are ammonia, alkali, acetic acid, chlorosulfonic acid and aniline, and now the first three are available, just the latter two.

Ning Qi is going to synthesize aniline first, he already has benzene in his hands now, but benzene cannot be produced in one step under the conditions he has now.

The most likely way to get this is to nitrate benzene into nitrobenzene, which is then reduced with iron powder to form aniline.

Nitrification is to use concentrated nitric acid, Ning Qi once again took out the big bag he brought from the Black Mountain, he is really grateful to God now, he actually put a volcano around him at this time, Yan Yunzhou is really not dead.

In Montenegro, there is not only the ammonium chloride he used, but also Chilean saltpeter, that is, sodium nitrate, which reacts with the concentrated sulfuric acid he already has in his hand and liquefies the gas produced to be nitric acid.

This step is not difficult, with nitric acid can directly react with benzene to produce nitrobenzene, and it is not difficult to find the iron powder needed for the later reduction.

Ning Qi didn't come out to eat dinner directly, Yan Yunzhou was a little worried about him, and asked people to send some snacks, but at that time, Ning Qi was preparing to prepare chlorosulfonic acid, and it was impossible to eat in the house, his hungry stomach only played a drum, but he was already short of the last step, he was ready to go all out, otherwise he wouldn't want to come in when he was full.

"Take it away, you can't eat in the house, tell Yan Yunzhou, I want to eat barbecue."

Ning Qi howled out with hunger in his throat, and Yan Yunzhou heard the voice in the main house, and couldn't help laughing, but immediately turned his head sideways:

"Dark, you ask people to go to the kitchen to see if there's any game they have brought back."

Dark Xuan immediately went to arrange, Yan Yunzhou took Ning's medicine every two hours, and the temperature only rose a little in the afternoon when the fever was most likely to occur, and then went down.

Dark Xuan's confidence in Ning Ji couldn't be greater now, he looked forward to Ning Ji being able to make the medicine used by the prince today, is that really the prince saved?

When he saw the colorless oily liquid collected in the glass bottle, Ning Ji closed his eyes, his neck and shoulders were sore, and he was hungry, and he almost wanted to scold his mother.

His grandmother's, he didn't do experiments so efficiently when he was in school, and he didn't dare to think about doing these things in a day when he was in graduate school.

Chlorosulfonic acid is not difficult to prepare in the case of concentrated sulfuric acid and concentrated hydrochloric acid, that is, it is necessary to be extra careful in protection, Ning Yi once again wrapped himself tightly, and this time he opened the window and emptied the people outside, and there was no one in the entire courtyard for a while.

Yan Yunzhou heard his command and guessed that he might be preparing the poisonous thing mentioned last time, and he couldn't put his mind at ease, so he stood at the door:

"Lord Wang, Gongzi Ning will be fine, you can sit for a while, I remember that Gongzi Ning likes the meat that the prince roasts, and we can follow it after a while."

Dark Xuan helped him sit down, and Yan Yunzhou calmed down and smiled:

"He's quite fond of eating, by the way, what's the answer from the kitchen?"

"There are no deer, but there are a few rabbits and sheep, I will let them be cleaned up, and Ning Gongzi will be able to send them over when he comes out."

"Lord Wang, don't just wait for Ning Gongzi, you still have to eat some at night, otherwise how can you take medicine?"

Yan Yunzhou didn't let people set up a meal just now in order to wait for Ning Yao, and at this moment, Dark Xuan asked people to serve some clear soup noodles, so they could cushion it.

Ning Ji finally let out a long sigh of relief when he looked at the few bottles in front of him, and hammered his sore back, he even had the feeling that he could summon a divine dragon after collecting five dragon balls.

But he thought about the reaction and suddenly remembered something.

Based on aniline, he needs to turn aniline into acetanilide first, this process is actually to add anhydride to aniline, fortunately yesterday when preparing aspirin, anhydride was ready-made, but there is a very important problem.

That is, there is a ratio of anhydride when it reacts with aniline, which should be a ratio of 2:1, but he forgot whether it is anhydride 2 or aniline 2 at the moment.

And this problem can't be tried blindly, because if these two substances are not in the standard ratio in the process of mixing, they will explode, yes, they will explode, although it will not kill him, but it will indeed explode.

He thought about the process after the synthesis of acetanilide, which reaction process would take several hours, after thinking of this, Ning Zhi gave up decisively, and reproduced it tomorrow, Yan Yunzhou could also use the medicine tomorrow night at the latest, he didn't force himself to stay up for another big night, and went out after tidying up the house.

"Lord Wang, Ning Gongzi has come out."

Yan Yunzhou immediately raised his head, and Ning Yi pushed the door in:

"All the raw materials are ready, it's almost tomorrow to synthesize, Dark Xuan, you send someone to guard the house at night, can't let anyone in, many of the things there are highly poisonous, no one can touch them."

"Yes."

Dark Xuan didn't know why the raw materials used to make medicine were highly toxic, but it was definitely right to listen to Ning at this moment.

Yan Yunzhou looked him up and down:

"Are you alright? If you're hungry, come on, go and tell the kitchen to bring the meat. ”

Yan Yunzhou opened his mouth while pouring water for Ning Qi, and Ning Qi took the water and drank it with a bang, he was really hungry:

"Barbecue?"

Yan Yunzhou nodded and smiled:

"Well, Ning Gongzi wants to eat, how could he not have it?"

Ning blamed himself for changing his clothes in the room, and then the whole person collapsed on the chair, Yan Yunzhou looked at him and rubbed his shoulders from time to time to know that he was uncomfortable:

"Shoulder pain? You go and lie down and I'll give you a push. ”

Ning Ji turned around and suddenly felt that something was wrong, why couldn't they raise a few maids around their ancient officials, rubbing their shoulders and beating their legs, why had he never seen such a person around Yan Yunzhou?

"I said prince, you are a prince anyway, why don't you even have a massage and leg beating in the house?"

Is this scientific?
