The tall equipment, busy workers, roaring steam pumps, constantly rotating water wheels, and carriages walking back and forth on the railway tracks made Yuwen of the factory feel that he had come to the industrial society.

Compared with the pleasant pastoral scenery, Yuwen Wen prefers the "industrial style" with thick smoke. At this moment, he wears a "hard helmet" on the high platform in front of a facility, listening to people introducing the operation of the workshop.

The speaker is Liu Yang, a Taoist priest who practices the way of chemistry. Liu Yang is no longer the master of Wuzhuang Temple in Huangzhou, but as the "general engineer" of the chemical industry, he led his technical team to Yecheng to open a chemical factory.

At this moment, he pointed to the lead chambers in front of him and introduced the production process of sulfuric acid to the emperor.

Yuwen Wen looked at the equipment in front of him and listened attentively.

Sulfuric acid, in alchemy, is called "alum oil" or "green alum oil". After the efforts of Liu Yang and countless alchemy Taoist priests, they can finally mass produce this strong acid.

The first set of sulfuric acid production equipment appeared in Xiyang, Huangzhou. The preparation process has been continuously improved and can be practical.

On this basis, the two sets of sulfuric acid production equipment put into production in Chang'an and Guangling soon started to operate normally. The fourth set of production equipment located in Yecheng has now completed the "test operation" and will be officially produced soon.

To provide strong support for the chemical industry, which is still in its infancy, the first thing that benefits is the printing and dyeing industry. A large number of colorful compounds are used by dyeing workshops to experiment with whether they can be used for dyeing cloths.

It was sunny in the afternoon. Yu Wenwen listened to the explanation and read the information. He looked at the spectacular production equipment in front of him. He felt that his blood was boiling. He finally mastered the key technology of large-scale preparation of sulfuric acid.

After more than ten years, the total cost is less than one million RMB (discount), and I finally got it!

Looking at Liu Yang with scars on his face and his "Daoist friends" with vicissitudes, Yu Wen Wen felt very moved. Without these local chemists who "transferred" from alchemy, his dream would not take long to be realized.

Liu Yang had an accident in a chemical experiment, leaving hideous scars on his face, and other Taoist priests also had more or less color in various experimental accidents, but this did not affect everyone's enthusiasm at all.

Refining immortal elixirs is no longer their goal, and the way of chemistry has made the alchemists led by Liu Yang go crazy. After countless days and nights, countless experiments, their discoveries have become more and more and more, and they feel more and more accomplished.

Industrial production of sulfuric acid is the crystallization of countless people's efforts.

In alchemy, heating green alum can obtain green alum oil, which is a corrosive liquid. It tastes a little sour in the mouth. If concentrated, it will be more corrosive. Under Yu Wenwen's guidance, Taoist priests such as Liu Yang knew that this green alum oil was called "sulfuric acid" and its corrosiveness (acidity) was called "oxidation".

The process of producing sulfuric acid has been improved many times and is no longer made by heating green alum to produce sulfuric acid.

The initially improved acid production process was to introduce the "sulphur-containing" waste gas of the coal-fired boiler into the spray tower, thereby obtaining "dilute sulfuric acid". Such "dilute sulfuric acid" has low concentration and many impurities.

However, the yield is large, which is more than the amount of sulfuric acid obtained by heating green alum.

Based on the concept of "lead room method" proposed by Yuwen Wen (Yuwen Wen only knows the name), Liu Yang finally found a way after continuous exploration, countless failures, and years of exploration.

This "lead chamber method" is to heat sulfur and manure nitrate (crystallization obtained from the civilized process of gunpowder industry) together, and to induce the gas to "pass water" in the lead chamber, and you can obtain highly acidic sulfuric acid.

The "lead chamber method" is constantly improved and successfully practical. When they can stably prepare a large amount of sulfuric acid, the "chemical reaction" becomes much more wonderful.

For example, Taoist priests who have obtained treasures use sulfuric acid to "react" with various substances. New "reaction forms" and new compounds continue to appear, making more and more Taoist priests forget to eat and sleep.

They found that dissolving table salt with concentrated sulfuric acid will produce a irritating gas. This gas is dissolved in water, and the water is also acidic. It is obvious that this is another acid.

Because it comes from salt, it is named "Hydrochloric acid".

After continuous improvement of the process of preparing hydrochloric acid and spending countless money on grains, it has finally been practical and can produce hydrochloric acid with a large amount of concentration. With sufficient hydrochloric acid, the chemical reaction becomes more exciting.

There is more than this good news. When Taoists distilled saltpeter or manure, they found that distillation would produce irritating gas. After this gas was absorbed by water, it was an acidic substance.

Because it comes from saltpeter or feces, this acid is called "nitric acid".

However, such a process is inefficient in preparing nitric acid, consumes a lot of impurities.

After continuous experiments, Taoists found that nitric acid can also be prepared by dissolving saltpeter with sulfuric acid. They referred to the preparation process of hydrochloric acid and improved the preparation process of nitric acid, and finally made the preparation process of nitric acid practical.

This was the beginning of this year. The first set of practical nitric acid production equipment was put into production in Xiyang, Huangzhou. The factory was located next to the sulfuric acid factory and hydrochloric acid factory.

Yu Wenwen, who learned about the practical news of nitric acid production, was excited at the time, like a child, jumping and laughing.

Sulfuric acid, hydrochloric acid, and nitric acid are collectively called "triacids", which are the basis of the chemical industry.

Although the preparation process of nitric acid is a bit complicated, the yield is not very high, and the purity is relatively low, this is great news for Yuwen Wen.

If you have three acids, will it be far away from two alkalis?

He burned money for more than ten years, and finally got the result. How could he be unhappy?

In order to celebrate this historic breakthrough, Yuwen Wen had a "one-choose three" that night and fought with three "female heroes" for a night before he calmed down.

Another reason why he was so excited was that the emergence of three acids means that the emergence of three chemicals is not far away, and these three chemicals can be called "three heroes".

First, nitrofiber.

Nitrogen fiber is a strong explosive, and its power is much higher than that of black gunpowder. Not to mention it is used in war, but just for building mountains, building roads or quarry, it is a powerful tool.

For Yuwen Wen, the preparation of nitrocellulose fiber is very simple, that is, soak cotton in nitric acid, and as long as you pay attention to the reaction conditions, you can mass-produce nitrocellulose fibers.

The second hero is nitroglycerin.

After refining glycerin from oil and treating it with nitric acid, the strong explosive "nitroglycerin" can also be obtained.

The third hero is Thunder Mercury.

If you use acid to treat mercury (mercury), you will get "mercury lysate", that is, thunder mercury. With thunder mercury, you will have a fixed-loading bullet, and then the emergence of a gun afterwards is no longer a dream!

Yu Wen Wen, who was extremely excited, immediately ordered the Wuzhuangguan experimenters to start researching nitrofiber, nitroglycerin and raze mercury. He wanted to make these "three heroes" use it for his own use.

Yuwen Wen allocated a lot of money for this purpose as a pension for the casualties in the experimental accident.

From that day on, he was waiting for the good news with confidence, waiting for the emergence of nitrocellulose, nitroglycerin and ramide mercury.

But until now, he hasn't waited.

Under heavy protection, the experimenters of Wuzhuangguan soaked cotton with nitric acid, but did not produce any special "nitrocellulose fibers".

They use nitric acid to soak the so-called "glycerol" extracted from the oil, and they do not produce any special "nitroglycerol".

They also used triacids to react with mercury, and did not produce any "crazy" "rain mercury".

What's the problem?

With Yuwen Wen’s few chemical knowledge left, the problem that can be imagined is that nitric acid is impure and the concentration is insufficient, so the “nitrification” is not successful.

Or the triacid has too many impurities, which causes the chemical reaction to fail to proceed normally; or the so-called "glycerol" is not glycerol at all, even if it is, it may not have enough purity and too many impurities.

In addition, various nitration reactions and acidification reactions require a third substance to "catalyze", that is, the correct catalyst needs to be found to assist the three reactions in normal progress.

Therefore, it is still far from successfully recruiting the "Three Heroes". Perhaps it will take ten or even twenty years to purify nitric acid alone. Yu Wen Wen was taught to be a human being by reality, and all kinds of crazy thoughts have to be put away.

Thinking of this, Yuwen Wen looked at Liu Yang and others without any blame. With the ability of the current era, it is a miracle that he can produce three acids, and Yuwen Wen will not demand anything.

Liu Yang and fellow Taoists developed the production process of three acids for him, and his reward was very generous, enough to make these chemists worry-free for three generations of food and clothing.

Liu Yang has married and has a son. The same is true for the others. Yuwen Wen wants to take these chemists as an example to let the world see how he cherishes talents.

Although the chemical industry he burned for money was still very immature, it was a big breakthrough for this era. Yuwen Wen firmly believed that as long as he continued to invest manpower and material resources, there would be a day for a comprehensive breakthrough.
