The whale oil in the other pot was already boiling at the beginning, and Shen Yue asked Shen Qi to withdraw the firewood in the stove to maintain the temperature.

At higher temperatures, the saponification reaction will be more complete, and at the same time, the methanol and other substances produced in it will be evaporated.

Shen Yue scooped out a scoop of yellowish caustic soda solution from the pot with a special long-handled gourd scoop and poured it into the funnel of the filtration device.

Inside the filter device, there are more than 10 layers of gauze made of different thicknesses, and between each two layers of gauze are filled with coarse sand washed with clean water. Once there are too many impurities in the filtration device and affect the filtration, the whole thing can be replaced directly.

Seeing that the designed filtration device had a remarkable effect, Shen Yue nodded with satisfaction.

Putting down the gourd scoop in his hand, he picked up a wooden stick and began to stir it in the pot filled with whale oil, and a lump of yellowed soap like cotton wool began to form, and then floated in the pot.

At the same time, a large amount of water vapor rose from the pot, and a violent stench also emanated.

The ambient temperature is rising rapidly.

When the saponification reaction is carried out, a large amount of heat will be released, Shen Qi didn't understand, and stood aside and watched with some horror, while Shen Yue continued to operate calmly, and the beads of sweat the size of soybean grains on his forehead fell straight down.

"Shen Qi, add caustic soda water to the funnel!" Shen Yue stirred, and the clothes on his body were also soaked, and the sodium hydroxide molecules diffused in the air made the exposed skin feel sticky and uncomfortable.

Shen Yue also doesn't care about the impact of air pollution on human health, let alone the pollution that the chemical industry will pollute the environment.

wants to save his life, take back everything the Shen family has lost, become a small landlord as he wishes, guard his own land and wait for death...... Everything is expected to be done now, and if it succeeds, everything will be achieved soon.

The caustic soda solution in the whale oil pot has been consumed by the saponification reaction, and the whale oil has at least ten catties, and according to the proportion, at least five or six catties of caustic soda aqueous solution with high purity are needed to complete the saponification reaction.

No matter how it is stirred, it can no longer produce more flocculent soap base, and more caustic soda solution must be added to continue the reaction.

In the pot of caustic soda solution, there is no need to heat up anymore, and the stove is full of large pieces of firewood, so naturally there is no need for Shen Qi to keep watching.

Shen Yue couldn't operate it alone, so he asked Shen Qi to help add caustic soda solution to the filtration device to keep the saponification reaction in the whale oil pot all the time.

"Don't add too fast, add slowly!" Seeing that Shen Qi was in a hurry, the reaction in the pot was too fast, and the corners of Shen Yue's mouth twitched.

"Young master, it's better for you to come, the little one will help you stir the pot." Shen Qi said with a sad face.

He was careful not to be splashed by the caustic soda water in the pot, and at first he accidentally touched the back of his hand, and it instantly became hot, which was really scary.

"Master, what are these things? The stench is terrible, what is the use? Shen Qi didn't understand, on a hot day, he should have found a good place to cool off, but the young master changed his temperament, and he didn't go out to pick up flowers and grass, nor did he wave outside, but braved the heat at home to make a foul smell.

Immediately, Shen Yue's mind opened and he asked Shen Yue, "Young Master, don't you want to use this thing to throw into the sea and poison the big fish?" ”

The stench is unpleasant, and the toxicity is certainly not small.

"You've got a big brain!" Shen Yue was made to smile bitterly by his dog's legs, and secretly said that it was terrible to be uneducated, and then explained, "The yellow flocculent floating on it is soap, which is used for bathing and laundry, and the decontamination effect is strong......"

"Isn't it just caustic soda water and oil, how did it become soap? What is soap? Isn't washing clothes with oil getting more and more oily? Shen Qi was shocked.

Is the young master stupid when he reads?

"Caustic water and oil have a chemical reaction together! Hurry up and get to work, you'll know when you're done. Now you can't figure it out. "Teaching chemistry to uneducated people, Shen Yue finds it very difficult.

In later generations, even junior high school students knew something, and in this year, people who learned to be rich and five cars were unheard of.

Just like in the Ming Dynasty, caustic soda and strong water have begun to be produced manually, and the output is not small.

Shen Qi has never been to school, he doesn't understand chemical reactions, and it is really difficult to explain, not to mention, he is not the person Shen Yue chose to be responsible for this production in the future.

The master and servant braved the scorching heat and were busy in the courtyard.

At the gate of the courtyard, two young men pinched their noses and hid in the shadows of the corner of the wall, stretching out their heads to the courtyard from time to time to see what the young master and the seventh brother were doing, and discussing the source of the stench, but they didn't understand what the young master was going to do.

The pungent stench gradually diffused in the small courtyard of the Shen family, making the people in the entire Shen house uneasy and sneezing. But the source of the pungent stench could not be found.

On a hot day, the air was filled with a foul smell, and Mrs. Shen, who was in a bad mood, felt that the subordinates of the Shen family were becoming more and more unruly, making the house so stinky.

"Yue'er, you arrange for someone to take a look, where is the stench coming from!" Mrs. Shen instructed Yue'er with an unkind face.

Yue'er has been covering her nose with a handkerchief, and it is uncomfortable to stay here, so she simply took the two little girls out to find the source of the stench.

Xu Yaozong rode a horse, led by Ma San to the Shen family, and asked Shen Yue about whaling all the way.

Ma San was articulate, learning from the storyteller in the teahouse, and told Shen Yue's whaling process thrillingly, and Xu Yaozong, who was well-informed, was also nervous when he heard it.

I heard that Shen Yue's giant crossbow was not used for water warfare, but for whaling, that is, I understood that this kid was arranging everything before he arrived at Longshan, and those military bullies were not easy to clean up, so he simply let Shen Yue deal with it.

Before he arrived at the Shen family's courtyard, there was a faint pungent smell in the air, and Xu Yaozong didn't care about it at first.

The closer I got to the Shen family, the more obvious the smell became, and I sneezed several times in a row.

......Outside the courtyard of the Shen family, Xu Yaozong was just about to dismount, and the jujube red horse, which had been snorting under his crotch, finally couldn't bear the pungent stench, and the person stood up, if it weren't for Xu Yaozong's dexterity, he would have to fall down.

"Dog thing! Want to give Lao Tzu a horse? Xu Yaozong finally appeased the jujube red horse, but the horse kept digging its hooves, snorting, and restless.

"Ma San, your young master made a special trip to invite the official to smell this stench? ......" Xu Yaozong could only let the little guy who followed behind him lead the horse to the side, and asked Ma San with an unkind face.

Where does Ma San know!

"My lord, the villain came to invite the adults when he got off the boat, I ......really don't know what happened at home, I really don't know" Ma San had a bitter face, he also wondered, when he left in the morning, the family was fine.

"Hurry up and call your young master out!" Walking to the door, the stench was even worse, and Xu Yaozong turned to retreat.
