Sulfur burned in the air to produce sulfur dioxide. Wang Ji was wondering why he couldn't use the reaction between sulfur dioxide and oxygen to produce sulfur trioxide and sulfuric acid.
Not only had he thought about it, but he had also done a lot of experiments recently, all of which ended in failure!
Li Zexuan heard this and couldn't help but secretly praise Wang Ji. This old man was very talented in the field of "Chemistry". He could even comprehend by analogy!
"Mr. Wang, it's not that sulfur dioxide can't continue to react, but if they want to react further, they need a catalyst! This is mentioned in the second volume of "Chemistry"! "
Using sulfur dioxide to produce sulfuric acid was the most commonly used method in modern industry. The raw material was pyrite (the main component was ferrous sulfide), which was calcined at high temperature to produce sulfur dioxide. Under the action of the catalyst and high temperature, sulfur dioxide formed sulfur trioxide, which was absorbed by 98.3% sulfuric acid to produce pyrosulfuric acid. Finally, water was added to produce sulfuric acid!
"Catalyst? What kind of catalyst can catalyze the reaction between the two? "
In the first volume of "Chemistry", there was an introduction to catalysts, but Wang Ji didn't know what catalysts could catalyze the oxidation of sulfur dioxide.
"Platinum or vanadium pentoxide!"
Li Zexuan thought for a while and said lightly.
"Platinum? Vanadium pentoxide? Yamachō, where can I buy these two things? "
Wang Ji frowned and asked.
Li Zexuan smiled helplessly and said, "Ah! These two things aren't sold anywhere! Especially the first one, as far as I know, it's very rare in the whole world! As for vanadium pentoxide, it can be extracted from the ammonium metavanadate in the vanadium ore, but as of now, no one in Tang Dynasty knows the use of the vanadium ore, let alone where the vanadium ore is! "
Wang Ji immediately said anxiously, "Yamachō, it doesn't matter if no one knows! We can send people to look for it! With this catalyst, we can produce sulfuric acid in large quantities! The current method of producing sulfuric acid from green alumina isn't suitable for mass production! "
He had heard Li Zexuan mention the importance of sulfuric acid several times before. After spending so much time together, Wang Ji deeply understood a principle: if Li Zexuan said it was important, then it must be important! Li Zexuan said that platinum and vanadium pentoxide could catalyze the further reaction of sulfur trioxide with oxygen, so it must be possible!
Unlike normal students, Wang Ji, who had read the "Chemistry" textbook and had personally done a lot of experiments, was completely convinced by Li Zexuan's knowledge in chemistry!
At this time, Li Zexuan closed his eyes and fell into deep thought. Seeing this, Wang Ji quickly shut his mouth and did not dare to disturb him again!
Actually, Li Zexuan was trying to recall which area had the most vanadium ores on the mineral distribution map from his previous life.
If it wasn't for the fact that he now had super abnormal spiritual power, he wouldn't have been able to recall this thing at all. After a full quarter of an hour, Li Zexuan finally opened his eyes and said, "What Mr. Wang said just now makes sense. The vanadium mine is very important to the workshop's future technological advancement. We must send someone to look for it! I've just deduced that there should be a lot of vanadium mines in the Jiannan Circuit! "
The so-called Jiannan Circuit mainly referred to the modern day Sichuan region. Back then, after the Qin Dynasty destroyed Ba and Shu, they implemented the system of prefectures and counties in Sichuan. Ba and Shu prefectures were established in the former Ba and Shu prefectures. In the fifth year of the reign of Emperor Wu of Han, the Sichuan region was designated as Yi Province. In the first year of Zhenguan, Li Er abolished the system of prefectures and changed Yi Province to Jiannan Circuit.
In modern day China, vanadium mines were distributed in nineteen provinces, cities, and autonomous regions. Among them, Sichuan had the most, with nearly thirteen million tons of vanadium ore reserves!
Searching for vanadium ores was a time-consuming and laborious task. However, it wasn't only Wang Ji who wanted to send people to look for them. Li Zexuan also wanted to send people to look for vanadium ores as soon as possible. As a modern person, no one understood the importance of sulfuric acid more than him. Putting aside the daily necessities derived from sulfuric acid like pigments, detergents, and cosmetics, for now, Li Zexuan felt that if the Tang Dynasty could produce sulfuric acid in large quantities, it should first be used in fertilizers, metallurgy, and petroleum industries. These three industries were all inseparable from sulfuric acid!
When the conditions were ripe, they could also use sulfuric acid to introduce batteries. With sulfuric acid, it would be much easier to manufacture electric scooters!
Going off topic, the production of nuclear fuel for nuclear reactors, the preparation of titanium, aluminum, and other alloy materials used in reactors, as well as titanium alloys used in rockets, supersonic jets, and man-made satellites were all directly or indirectly related to sulfuric acid.
Sulfuric acid was really the cornerstone of the national defense industry!
When Wang Ji heard Li Zexuan say that there was a vanadium mine in the Jiannan Circuit, he couldn't help but be delighted. He exclaimed in admiration, "Could it be the disciple of Spiritual Master Ling Xu? This old man admires Yamachō's geomancy!"
Old Wang thought that this result was really calculated by Li Zexuan. In addition, he had also heard about Fubin's previous trip to Hedong Circuit to look for vanadium ores. Therefore, he was even more impressed with Li Zexuan!
"Haha! Alright! Mr. Wang, you go ahead with your work! Let's talk about the vanadium mine after the new year! You also have to pay attention to your rest during this period. Don't tire your body out! "
Li Zexuan felt a little guilty under Wang Ji's fanatical and worshipful gaze and hurriedly ran away.
… … … …
Although sulfuric acid was very important, the new year was equally important. The Chinese people's feelings towards the new year had not weakened for thousands of years. Li Zexuan didn't want to send people to Sichuan to look for vanadium ores at this critical juncture near the end of the year!
Ma Zhou was very efficient. In the afternoon, he had written a "beautiful article" about the free medical consultation. After Li Zexuan read it, he couldn't help but secretly sigh, "How can a golden fish be a fish in a pond?". This small temple of his would probably not be able to accommodate a great Buddha like Ma Zhou in a few years!
There were some things that he could change, but there were some that he couldn't. A person like Ma Zhou who was full of talent would definitely become a country's Prime Minister in the end!
The next day, Datang Daily's headlines announced that with the support of the Warm Tang Foundation, Sun Simiao and two former doctors from the Imperial Physician Department were planning to hold a free medical consultation in the surrounding counties of Chang 'an City.
When the news spread, thousands of people cheered!
Regardless of whether it was modern or ancient times, there were many people who couldn't afford to fall sick. They didn't even dare to fall sick because sometimes, a seemingly insignificant illness could very well drag down an entire family!
Now that Sun Simiao, the Tang Empire's publicly recognized miracle doctor, was planning to hold a free medical consultation, many families with patients would be reborn because of this free medical consultation! How could the people not be happy?
Those who knew the news spread it everywhere. In an instant, the people of Chang 'an City and its surrounding areas were beaming with joy as if it was the new year!
