Sulfur burns in the air to produce sulfur dioxide. What Wang Ji wondered is why it can't produce sulfur trioxide through the further reaction of sulfur dioxide and oxygen to make sulfuric acid.

Not only did he think about it, but he also did a lot of experiments recently, all of which ended in failure!

Li Zexuan heard this, and couldn't help but secretly praise Wang Ji, the old man who is still very talented in "Chemistry", and he will understand by analogy!

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

Using sulfur dioxide to prepare sulfuric acid is one of the most commonly used methods in modern industry. The raw material is pyrite (the main component is ferrous sulfide), which is calcined at high temperature to generate sulfur dioxide. The sulfur dioxide is under the action of a catalyst and high temperature. Generate sulfur trioxide, absorb with 98.3% sulfuric acid to obtain pyrosulfuric acid, and finally add water to obtain 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 does not know what catalysts can promote the further oxidation of sulfur dioxide.

"Platinum or vanadium pentoxide!"

Li Zexuan thought for a while and said lightly.

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

Wang Ji frowned and asked.

Li Zexuan smiled helplessly and said, "Heh! 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 made from vanadium. The ammonium metavanadate in the ore is extracted, but as of now, no one at Datang knows the purpose of vanadium ore, and no one knows where the vanadium ore is!"

Wang Ji immediately said anxiously: "Shanchang, no one knows it's okay! We can send someone to find it! With this kind of catalyst, we can make a large amount of sulfuric acid! Now we use green alum to make dilute sulfuric acid. The method is not suitable for mass production at all!"

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

Different from the "Bujue Mingli" of ordinary students, Wang Ji, who has read through the "Chemistry" textbook and has done many experiments by himself, has long been conquered by Li Zexuan's profound knowledge in chemistry!

At this time, Li Zexuan closed his eyes and fell into deep thought. Upon seeing this, Wang Ji closed his mouth quickly, not daring to interrupt!

In fact, Li Zexuan is now recalling the mineral distribution map of his previous life. Which area has the most vanadium ore!

If it weren't for his super abnormal mental power now, this thing would never be recalled. After a full quarter of an hour, Li Zexuan finally opened his eyes, and he said, "Mr. Wang just said it is reasonable. The vanadium mine is very important to the future technological progress of the workshop. Someone must be sent to find it! I just deduced it. After a while, the result is that there should be a lot of vanadium ore in Jiannan Road!"

The so-called Jiannan Road mainly refers to the modern Sichuan area. After Qin destroyed Ba and Shu, the system of prefectures and counties was implemented in Sichuan, and Ba County and Shu County were established in the original Bashu area. Emperor Wu of the Han Dynasty was sealed for five years, and the Sichuan area was designated as the Ministry of Yizhou. 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, with vanadium ore reserves as high as 13 million tons!

Ore prospecting is a time-consuming and laborious task, but not only Wang Ji wants people to find it, but Li Zexuan also wants to send people to find vanadium ore as soon as possible. As a modern person, no one understands the importance of sulfuric acid better than him. The derivatives of sulfuric acid, detergents and cosmetics are not mentioned for the time being~IndoMTL.com~Li Zexuan thinks that if Datang can produce sulfuric acid in large quantities, it should be applied first in the fertilizer, metallurgy and petroleum industries. All three are inseparable from sulfuric acid!

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

Also, if nitric acid can be prepared later, then a high explosive (tnt) can be made.

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

Furthermore, the production of nuclear fuel for nuclear reactors, the preparation of alloy materials such as titanium and aluminum for reactors, and the titanium alloys used in the manufacture of rockets, supersonic jets and artificial satellites are all combined with sulfuric acid. Have a direct or indirect relationship.

This thing is really 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 real disciple of Lingxu, and Shan Chang's Feng Shui technique is old and admired!"

Lao Wang thought that this result was really calculated by Li Zexuan. In addition, he had also heard about Fubin's previous trip to Hedong Road to search for mines, so he admired Li Zexuan even more!

"Haha! Alright! Mr. Wang, you should be busy! Let's talk about vanadium mining next year! You have to take a rest recently, don’t get tired!"

Li Zexuan was a little guilty when he saw Wang Ji's fanatical look in his eyes, and he quickly turned away.

.………………………………

Although sulfuric acid is very important, it is also important for the New Year. The Chinese people's love for the New Year has not been weakened for thousands of years. Li Zexuan does not want to send people to Sichuan to look for mines in this near-year-old knot!
