Sulphur burns in the air to generate sulfur dioxide. Wang Ji thought about why it could not be further reacted with sulfur dioxide and oxygen to generate sulfur trioxide, thereby producing sulfuric acid.

Not only has he thought about it, but he has also done a lot of experiments recently, all of which have ended in failure!

Hearing this, Li Zexuan couldn't help but praise Wang Ji, the old man, for being very talented in "Chemistry".

"Mr. Wang, it's not that sulfur dioxide can't continue to react, but if they want to react further, they must have a catalyst! This will be mentioned in the "Chemistry" textbook in the second volume!"

Using sulfur dioxide to prepare sulfuric acid is the most commonly used method in modern industry. The raw material is pyrite (the main component is ferrous sulfide), which is calcined at high temperature to generate sulfur dioxide. Sulfur, absorb with 98.3% sulfuric acid, get pyrosulfuric acid, and finally add water to get sulfuric acid!

"Catalyst? What catalyst can catalyze the further reaction of the two?"

In the first volume of "Chemistry", there is an introduction about catalysts, but Wang Ji did not know any catalysts that could promote the further oxidation of sulfur dioxide.

"Platinum or vanadium pentoxide!"

Li Zexuan thought for a while and said lightly.

"Platinum? Vanadium pentoxide? Chief, where can these two things be sold?"

Wang Ji asked with a frown.

Li Zexuan smiled helplessly, spread his hands and said: "Oh! These two things are not sold anywhere! Especially the first one, as far as I know, the whole world is very rare! As for vanadium pentoxide, it can be obtained from vanadium ore. Ammonium metavanadate is extracted, but as of now, no one in Datang knows the purpose of vanadium ore, and no one knows where the vanadium ore is!"

Wang Ji immediately said anxiously: "Shan Chang, it doesn't matter if no one knows! We can send someone to look for it! With this catalyst, we can produce a large amount of sulfuric acid! Now the method of using green alum to make dilute sulfuric acid is completely basic. Not suitable for mass production!"

He has heard Li Zexuan say that sulfuric acid is very important several times before. After getting along for so long, Wang Ji has deeply understood a truth: that is, if Li Zexuan said that what is important, then it must be very important! Li Zexuan said that platinum and vanadium pentoxide can catalyze the further reaction of sulfur trioxide and oxygen, so it must be able to catalyze!

Different from the ordinary students' "not aware of the calendar", Wang Ji, who read through the "Chemistry" textbook and did many experiments by himself, has long been conquered by Li Zexuan's profound knowledge in chemistry!

At this moment, Li Zexuan closed his eyes and fell into deep thought. Seeing this, Wang Ji quickly closed his mouth, daring not to disturb him any more!

In fact, Li Zexuan is recalling the mineral distribution map of his previous life, which area has the most vanadium mines!

If it weren't for his super perverted mental power now, this thing could not be recalled at all. After a full quarter of an hour, Li Zexuan finally opened his eyes, and he said, "Mr. Wang is just right. Vanadium mine is very important for the future technological progress of the workshop, and we must send someone to find it! I just deduced it. After a while, the result is that there should be a lot of vanadium mines around Jiannan Road!"

The so-called Jiannan Road mainly refers to the modern Sichuan area. After Qin destroyed Ba and Shu, the county system was implemented in Sichuan, and Ba County and Shu County were established in the original Bashu area. In the fifth year of Emperor Wu of the Han Dynasty, the Sichuan area was set as the Yizhou Department. In the first year of Zhenguan, Li Er abolished the state and county system and changed Yizhou to Jiannan Road.

In modern China, vanadium ore is distributed in 19 provinces, municipalities and autonomous regions, among which Sichuan has the most, and the reserves of vanadium ore are as high as nearly 13 million tons!

Prospecting for ore is a time-consuming and laborious job, but not only Wang Ji wants people to look for it, Li Zexuan also wants to send someone to find vanadium ore as soon as possible. As a modern person, no one understands the importance of sulfuric acid, pigments, detergents better than him. , cosmetics and other daily necessities derived from sulfuric acid will not be mentioned for the time being. Li Zexuan thinks that if Datang can produce a large amount of sulfuric acid, it should be applied first in the fertilizer, metallurgy and petroleum industries. All three of these are inseparable from sulfuric acid!

When the conditions are ripe, you can also use this to launch the battery. With this thing, it is much easier to build an electric vehicle!

Also, if nitric acid can be produced later, high explosives (tnt) can be made.

(tnt is trinitrotoluene, which is generated by benzene and concentrated nitric acid under the catalysis of concentrated sulfuric acid)

To go further, the production of nuclear fuel for atomic reactors, the preparation of titanium, aluminum and other alloy materials for reactors, and the titanium alloys used in the manufacture of rockets, supersonic jets, and satellites are all directly related to sulfuric acid. indirect relationship.

This thing really is the cornerstone of the defense industry!

When Wang Ji heard Li Zexuan say that there are vanadium mines in Jiannan Road, he couldn't help but smile and exclaimed: "It won't be a disciple of Lingxu, the feng shui master of the mountain is admired by old people!"

Pharaoh thought that this result was really calculated by Li Zexuan, and he had heard about Fu Bin's previous trip to Hedong Road to search for mines, so he admired Li Zexuan even more!

"Haha! Okay! Mr. Wang, you are busy first! Let's talk about the vanadium mine after the New Year! You have to pay attention to rest recently, but don't get tired!"

Li Zexuan was a little guilty at Wang Ji's fanatical admiration, so he hurriedly walked away.

. . . . . . . . . .

Although sulfuric acid is very important, the Chinese New Year is also important. The Chinese people's attachment to the Chinese New Year has not weakened for thousands of years. Li Zexuan did not want to send someone to Sichuan to look for mines at this critical juncture!

Ma Zhou's Office

The efficiency is very fast. In the afternoon, he wrote a "splendid article" about the free clinic. After reading it, Li Zexuan not only sighed, "How can the golden scales be in the pool?" I can't stand the great Buddha of Ma Zhou!

He can change some history, but he can't change some history. A talented person like Ma Zhou will definitely become the Saisuke of a country in the end!

On the second day, the headline of "Datang Daily" published a notice that with the strong support of the Nuan Tang Foundation, Sun Simiao, together with two former doctors of the Imperial Physician's Office, planned to hold free clinics in the counties around Chang'an City.

When the news came out, the people rejoiced!

Whether in modern times or in ancient times, there are many people who cannot afford to get sick, or even dare not get sick, because sometimes a seemingly inconspicuous disease may bring down a family!

Now that Sun Simiao, a well-recognized genius doctor in the Tang Dynasty, plans to hold a free clinic, why are the people unhappy?

People who knew the news ran around to tell them, and all of a sudden, the people around Chang'an City and Chang'an City were just like the Chinese New Year, with beaming expressions on their faces!
