After Li Wu left, Jiang Wei sat on the chair and thought about it for a while, then decided to go to the house he bought on the outskirts of Chang'an City, and called Li De.

This time, he decided to start working on TNT. Before making it, Jiang Wei had prepared mercury thunderate, which is the detonating charge of TNT.

First use nitric acid and mercury (an ancient medicine) reaction to prepare mercury nitrate, and then use the oxidation of mercury nitrate to add ethanol (methanol can also be) to generate mercury thunderate, pay attention to the temperature should not be too high, otherwise there will be a violent explosion ~ (details will not be written)

TNT is his most important reliance, and to find orphans, his idea is to create a private army with modern weapons. Escort his safety so that he can deal with things that he will not be able to cope with in the future. But obviously this is not something that can be done in a short period of time.

What we have to do now is to develop obscenely, don't wave.

When he came to the door of the house, Jiang Wei saw Li De waiting there, at this time, Li De had long since lost the breath of the villagers before, he had been a leader for more than a month, and he already had a little bit of the temperament of a senior administrator, and his skin had grown a lot whiter, coupled with a dress of satin fabric, he looked even more handsome and handsome, and his demeanor was betting, and he also had the confidence that he did not have before.

Jiang Wei nodded with satisfaction, the grandmother must be very happy to see her grandson become like this, right?

"Childe."

Li De bowed his hand, naturally maintaining his previous respect for Jiang Wei, and Jiang Wei, a man with the appearance of a scholar standing next to Li De, was very familiar with it, and it was the only scholar in Yunling Village, Li Tong.

"Childe."

Li Tong bowed, no longer had the arrogance before, since this period of time, Li Tong's family has also become rich because of the incubation technology, and at the beginning because of his collision with Jiang Wei, he was also taught by his father.

At this time, Li Tong had long been convinced of Jiang Wei, and even became a worshipper.

Jiang Wei smiled and nodded to Li Tong, and then said,

"Let's go, let's go in."

When he entered the house, Jiang Wei found that it was much cleaner than the first time, and it seemed that someone had come to clean it. He didn't care about this, but asked Li De to take him to see the cartridge.

The ten cartridges were stored in the side courtyard room, and all the way to the wing room, Jiang Wei looked at the cold iron cartridge lying quietly on the ground, and his eyes kept looking at the cartridge.

Looking at the length, it is about 80 centimeters in length, and the circumference should be 30 centimeters visually. It looks like a miniature version of a missile, but it looks ugly on the outside.

But this thing is not a missile, the missile is characterized by precision strikes, the structure is very complex, the most cutting-edge part is, infrared imaging guidance head, GPS receiver, and then separated by a buckle device, is the explosive. There is also a part of the design in the back, which is very complex.

And Jiang Wei's is much simpler, two-thirds of it is to place explosives, that is, TNT explosives, and one-third of the tail is propellant. That is, gunpowder. And explosives and gunpowder are not the same.

The main function of gunpowder is to make propellant, of course, it can be used as explosives, but the power is very small. Explosives, on the other hand, cannot be made into propellants.

Because gunpowder burns violently, although it has an explosive effect under certain conditions, explosives burn rapidly in a very short time, that is, explosion. The nature of combustion is different, and the effect is also different.

TNT, on the other hand, is explosives.

Today, Jiang Wei is here to start TNT production.

Jiang Wei also upgraded the protection work again, replacing the four-meter-long ventilation tube with an oxygen cylinder that enclosed the bamboo tube. Oxygen is obtained by heating saltpeter. The chemical formula is 2KNO3 heating ==2KNO2 + O2

With the oxygen cylinder made of bamboo tube, the process of the experiment is relatively safe and convenient.

After Li Tong and Li De, and Jiang Wei changed into protective clothing, they came to his temporary laboratory, which was covered with iron pipes.

"Li Tong, you are responsible for pouring hot water to control the temperature of the room, always pay attention to the thermometer display, I need to keep the temperature of the room at 30 degrees, no problem, right?"

Li Tong nodded,

"Childe, leave it to me."

Jiang Wei smiled with satisfaction,

"Li De, you are by my side and listen to my orders at any time."

The first material for making TNT is nitric acid, before Jiang Wei used saltpeter and concentrated sulfuric acid to make a part of nitric acid, which was used to make mirrors, and the chemical formula 2KNO3 + H2SO4 heating = = K2SO4 + 2HN03 (g)

Later, some saltpeter and nitric acid were collected one after another. In Xufu, every day when he is free, he immerses himself in making nitric acid, and so far, he has consumed 3,000 catties of nitric acid. If all of it is made into nitric acid, it can probably make 10,000 catties. However, due to the large number of them, he really has limited energy. And the 3,000 catties of nitric acid have all been transferred to this house.

And Song Cen Yue's practice of coke has also refined a lot of toluene, and so far, the amount of toluene is also 1,000 catties.

The first step is a stage of nitrification, that is, the preparation of mononitrotoluene MNT.

First of all, nitric acid, sulfuric acid with a concentration of a certain standard, as well as room temperature water and cold water, toluene.

The equipment for making it is two extra-large steel pots, which are placed on a stove, and the slightly smaller steel pots are placed in a larger steel pot. The height of the steel pot is higher than that of a person, so a ladder is also prepared so that people can stand on it and operate.

"Li De, pour cold water into the Dagang pot first, remember not to pour cold water into the small steel pot.

It didn't take long for Li De to pour nitric acid and warm water. The first step is to mix nitric acid and water in a cold water bath.

After some time,

"Okay, Li Tong, you go out first and start heating the water in the iron pipe."

"Oh."

Li De didn't understand this, so he nodded and went down.

Jiang Wei thought about it, this room had begun to be filled with poisonous gas at this time, and for safety reasons, he still reminded him,

"If you two smell something strange, run out at once, be quick. When I got a little outside, I took off my hood. Remember, it's not a joke, you know, if you're not careful, you know? ”

"Got it."

"Alright, go ahead."

A period of nitrification is not very difficult, and the temperature requirement is not high, mainly when toluene is added, it needs to be added slowly, not too fast. After adding toluene, Jiang Wei asked Li De to light the fire again, heat it on low heat, and then continue to put in toluene until the end of a period of nitration.
