In the experience of ordinary people, apart from the possibility of using sulfuric acid for experiments in student days, only when a third party intervenes do they have the desire to buy it. But for scientists, sulfuric acid has too many uses.

Basic chemical experiments are inseparable from sulfuric acid, and basic industry can be said to be based on a small number of concentrated chemicals - one of which is sulfuric acid. There will definitely be a factory producing sulfuric acid around any industrial city. If not, it means you have discovered a new business opportunity...

As for revenge against opponents, sulfuric acid has a more significant effect besides burning. It is usually used by one group of people to take revenge on another group of people - the famous nitroglycerin.

Like methamphetamine, nitroglycerin is a dangerous product that any qualified science and engineering student should know how to manufacture. In simple terms, nitroglycerin is an unstable substance that mixes concentrated sulfuric acid, concentrated nitric acid and glycerin. Of course, the actual operation The process is a little more complicated.

The last time Cheng Jinzhou purchased sulfuric acid through Shen Cong, the concentration was about 70%. Although it cannot meet the requirements of concentrated sulfuric acid, it at least shows that sulfuric acid has been widely used in this era. There are not many star warlocks who are proficient in alchemy, but they Products often have a stronger stimulating effect on people's livelihood. Just like the era when the Industrial Revolution was unfolding, physically manufactured machinery was used in industry, while chemically manufactured products were directly used on consumers.

There are many ways to purify sulfuric acid. Although Cheng Jinzhou is not good at experiments, he knows all the methods. And compared to the trouble and low power of black powder, nitroglycerine is more suitable for his current status: high power, high danger, and high efficiency, which can be called a model of the three highs.

Shen Cong looked at Cheng Jinzhou worriedly, and then at Cao Feng, who was wearing a star warlock robe, and said, "I'll send someone to bring some acid over, but don't do anything obvious."

Not doing something obvious and not doing this are completely different concepts. Naturally, Shen Cong had no good impression of Zhao Quanfu himself.

Cheng Jinzhou nodded and shook his head: "We need some other acids. The other one is glycerin."

He said and explained nitric acid. In the era when there was sulfuric acid, there was naturally nitric acid, but Shen Cong couldn't understand it himself, so he simply said: "I also went to the pawn shop last time. The chao Feng in the shop is said to have seen everything."

"That one..."

"Uncle Lin, he is very involved in the family business. Our butler joined the army." Shen Cong made a joke.

Cheng Jinzhou nodded and said simply: "Let's go to the pawn shop to have a look. It's more uncomfortable to wait here."

A broken restaurant not only has air leakage from all sides, but also has people watching. Once people are there, it loses its meaning.

The shopkeeper sent a group of people out half the door with both joy and worry. The street in front of the Liyuan was still crowded with people, especially the candidates from well-off families who wanted to take this opportunity to make a big splash. Those who succeed can hold a tail-burning banquet - the fish leaping over the dragon gate still has its tail, so it needs to be burned; the loser can also call friends to drink and drink away their sorrows - the number of people is huge in terms of absolute base, and the surrounding businesses People are also celebrating the holidays, acting as if they are doing real estate business in China.

The roads in the capital cannot be said to be spacious, and there are no restrictions on the shape of the carriages and horses. Everyone opened their arms and walked as comfortable as they could. However, no matter whether they were noble children or officials and civilians, they saw Cao Feng's star warlock robes and were indifferent. With one exception, they dodge away, leaving at least several times more space for them, just like the posture of a leader visiting.

According to legend, Star Warlocks are known to kill people in the street if they don't agree with each other, although this kind of slander has always been denied by the Star Warlocks who do these things.

Not far out of the restaurant, Lu Xu became impatient and said half-floating in the air: "Where are you going, I'll go there and wait."

"Take me with you, you are still a bodyguard." Cheng Jinzhou glanced at him helplessly.

Shen Cong immediately jumped out and said, "I'll show you the way."

Lu Xu grabbed Shen Cong and started flying upwards. The crowd on the ground had already made him uncomfortable.

Cao Feng smiled and said "offended", and grabbed Cheng Jinzhou's collar and floated into the air. It gave the latter the feeling as if he was riding an aerial motorcycle.

…

Lin Bo is indeed a person who is proficient in all kinds of items. What is particularly impressive is that he will consciously continue to add knowledge, even if he is already an old man, but since he sold it to Cheng Jinzhou Acid, he has I have read everything, and now when it comes to nitric acid and so on, it is amazing how many different specifications can be listed.

Scholars know everything about the world without going out. After a little contact, Lin Bo prepared everything Cheng Jinzhou needed without him having to worry about it.

About 80% concentrated sulfuric acid, basically satisfactory nitric acid, but unfortunately there is no ready-made glycerin - Cheng Jinzhou was prepared to pull Cao Feng and Lu Xu over and said: "Who can separate the products of the star array between you two?"

"Separation?" Lu Xu frowned, waved his right hand lightly, and rubbed up a layer of ground and said, "Is this so?"

The ground was so neat that even the stones were cut open. Shen Cong shrank back when he looked at it, and his hand even touched his neck inadvertently.

The cutting machines Cheng Jinzhou had seen were much more powerful than this one. He shook his head indifferently and said, "Are you going to separate matter, Mr. Cao?"

The advantage of the astrologers of this era in alchemy or chemistry lies in their ability to use star arrays to decompose or combine substances - in Xiao Cheng's opinion, it is probably through the action of high-energy particles and so on - from a good perspective Locally speaking, the star array enables today's astromancers to cross many steps and successfully obtain chemical products, thus affecting the development of chemistry. But on the negative side, the use of star arrays has allowed countless astromancers to All have lost the opportunity to discover and summarize the essence of chemistry.

Of course, in a world where magical star arrays can exist, feeling the essence of the star array may be a more important goal.

Scientists who first study biology must start with chemistry, and Cao Feng is no exception. He grabbed a handful of sulfuric acid with a slightly shiny hand. He didn't care that the sulfuric acid left behind corroded the ground. He concentrated on activating the star array on his wrist. Soon he saw that all the sulfuric acid was flowing out from the gaps in his fingers. Pure water, no acid at all.

After a moment, Cao Feng opened his palm and saw a small plate made of light gathered on the palm of his hand. On it was solid, solidified sulfuric acid.

Cheng Jinzhou stretched his neck, opened his mouth and said, "Is this artificial concentrated sulfuric acid you made?"

This is somewhat different from what he had in mind. I heard that the Americans spent a lot of effort in making napalm bombs back then. If they had Star Warlocks involved, they would probably add napalm bombs to their warehouses.

Cao Feng threw away the concentrated sulfuric acid on his palm on the ground. Different from the slightly dilute sulfuric acid, these guys with a concentration of at least 95% directly corroded a big hole in the bluestone ground, and then white streaks began to appear. Gas, probably because the stone contains more calcium carbonate.

Cheng Jinzhou couldn't laugh or cry. He wanted Cao Feng to help make glycerin. Concentrated sulfuric acid was not in short supply, but he couldn't explain it in words. He simply pulled Lin Bo and said, "Go find some fat first, pig fat." , pure fat meat.”

The favorite thing of city residents is pig fat, and they can find it in no time. While Cheng Jinzhou was waiting in the small yard, he took the opportunity to explain to Cao Feng how to extract glycerol from fat. If it was in a laboratory, just find some fat and add sodium hydroxide, and then salt it out to get glycerol. If there are chemical reagents, In a store, you can make things while the boss is looking for change, but in Daxia, finding sodium hydroxide is a bit troublesome.

However, from an alchemical point of view, strong bases such as sodium hydroxide will definitely be widely used by people, even if some gentlemen's chemistry laboratories are a mess. Cao Feng is no exception. It is not easy to simulate the properties of a strong base with a star array, but the essence of this experiment is to lengthen the carbon chain. To achieve this, the star array has countless solutions.

Dozens of kilograms of white pork were brought in in a basin. Cheng Jinzhou felt a little horrified when he saw it. On the contrary, Lu Xu and Cao Feng didn't take it seriously and started playing with interest - the star warlock wanted to find something interesting. Things are not easy either.

Any young man with free access to a laboratory, if he is curious enough, can easily make nitroglycerin and methamphetamine - in fact, the gentlemen who usually make these things don't even need a laboratory.

The simplicity of these two compounds is inversely proportional to their fame. Cheng Jinzhou can guide Cao Feng to do the same thing with almost no effort.

After preparing concentrated sulfuric acid, nitric acid and a sufficient amount of glycerin, further combinations did not even require Cao Feng to use the star array. Except for Lu Xu's occasional curiosity to shake the newly produced nitroglycerin, the process of the experiment Nothing unusual happened.

After Shen Cong brought the three of them to his yard, he said nothing again. It was not until Cheng Jinzhou carefully placed the glycerin in the porcelain bottle that he asked, "Is this thing dangerous?"

"It's more than just dangerous." Cheng Jinzhou looked at the bottle almost as if he were eye-to-eye with each other and said, "The number of people who have died because of transporting this thing is no less than experts and professors."

"What kind of dangerous method?" Shen Cong took two steps back.

Cheng Jinzhou smiled when he saw it and lied to him: "If you really want to know, just think of it as timely poison."

Glyceryl trinitrate will indeed make you dizzy when you smell it, but it is not easy to kill one person. At least it is not cost-effective economically. It can obviously kill a whole group of people, but it is difficult to kill one or two people.

Thinking of the existence of Zhao Quanfu, Shen Cong didn't want to know what Cheng Jinzhou was going to do, so he waved his hand and said, "I'll prepare food for you. You just have to play first."

With that said, he slipped out through the crack of the door with a whoosh.

"Let's make a little more and make up 5 kilograms." In Cheng Jinzhou's memory, it would take almost a suitcase of nitroglycerine to blow up an entire building. Although it was once the most powerful ordinary explosive in the world, it is a product of the 18th and 19th centuries, and it is difficult to achieve Hollywood effects.
