At present, the Hey Gunpowder used by countries around the world and the new Gunpowder developed by Zhao Peng are actually mixtures, not compounds. Various explosives in later generations include both mixtures and compounds. However, whether they are mixtures or compounds, if they want to make explosives, chemicals are needed to chemically react the substances before they can obtain the raw materials for producing explosives.

First of all, sulfuric acid is known as the mother of chemical industry. Only after sulfuric acid can nitric acid be produced in the easiest way.

Because with the process of this era, it is impossible to skip sulfuric acid and directly produce nitric acid by ammonia oxidation. Only a simpler reaction method of nitrate and sulfuric acid can be used to produce nitric acid.

With sulfuric acid and nitric acid, more advanced ejection drugs can be produced: smokeless gunpowder, and can also produce more powerful and invincible explosives.

Gunpowder and explosives are actually different. Gunpowder needs to be in a sealed space before it can explode. If there is no sealed space to constrain the gas generated when the gunpowder is burning, it will not explode; while explosives are different. Even if the explosives are placed in the open air, they will explode violently after detonation. Therefore, generally, gunpowder is used as the launching medicine for guns and cannons, while explosives are used as the filling medicine in shells and mines.

When they walked to the entrance of the Chemical Experimental Building, everyone looked up and saw that this was a six-story building. With the birth of cement, it is not difficult to build a six-story building in the Ming Dynasty. With cement, it is easy to build a high-rise building.

At the entrance of the Chemistry Experimental Building, there were also Jinyiwei guards guarding the gate. Jinyiwei who was guarding the gate carefully checked their waist cards and documents before putting Zhao Peng and the others into the building.

"Entertainment Father, the guard is too tight here. When we walk into the inside from outside, we have passed four levels before we can enter this building." Chen Xinyuan next to us said.

Zhao Peng smiled and said, "This is the core of the powerful weapon of the producer country. Of course, we must be on high alert. Everyone who works here is a precious talent in our Ming Dynasty! With their efforts, we can create more powerful weapons."

Wang Quan said: "Mr. Marquis, with our current weapons, as long as the output keeps up, defeating Jiannu and recapturing the Central Plains is no problem. Why do we need to develop more powerful weapons?"

"Defeat Jiannu and recover the Central Plains, we have only completed the first goal. Our goal is to look at the world! We must make the whole world surrender to our Ming Dynasty!" Zhao Peng said.

When he walked into the laboratory, he saw rows of flasks, test tubes, alcohol lamps and other experimental equipment placed inside. Song Yingxing, who was hired by Zhao Peng for a high salary, was busy in the laboratory with a group of students.

Based on the experimental textbook compiled by Zhao Peng, Song Yingxing and others first used sulfur to burn it and obtained a gas with a pungent smell, which was actually sulfur dioxide. Then sulfur dioxide was injected into a glass jar, and there was a layer of metal wire mesh flashing with silver-white light in the jar. The glass jar was heated on the alcohol lamp. The gas produced was then led out through a glass tube and flowed into the top of a thin-mouthed flask, which was filled with water.

The gas reacts chemically with water and turns into a colorless and transparent liquid.

The liquid was carefully poured into an opaque bottle by Song Yingxing and his students.

Zhao Peng explained to the Jinyiwei around him: "This is to use laboratory methods to produce green alum oil, that is, sulfuric acid. With sulfuric acid, we can produce more things."

Green alum was a Chinese medicine in ancient China. In ancient China, alchemists once mixed green alum with rice vinegar and placed it in a sealed alchemy furnace for heating, and obtained something they called "green alum oil", that is, sulfuric acid.

Because the corrosiveness of sulfuric acid is too strong, the method of ancient alchemists in producing "green alum oil" was not passed down. This kind of thing is not popular. The ancients did not know that this kind of thing played an important role in weapon production, so the ancients regarded "green alum oil" as a dangerous waste, and since then, no alchemists have made this kind of thing.

The invention of gunpowder was also discovered by alchemists by chance. Although this kind of thing is very dangerous, the Chinese discovered that this kind of thing can be used to produce fireworks and firecrackers, and later discovered their military uses. Therefore, the method of gunpowder manufacturing was passed down, while the production method of green alum oil was ignored.

Although green alum in nature can also be used to produce sulfuric acid, the amount of green alum is rare and cannot meet the needs of mass production of weapons in the future. Therefore, Zhao Peng still needs to study industrial methods to produce sulfuric acid.

If you want to make sulfuric acid in industrial use, you must first obtain sulfuric acid in the laboratory. Therefore, the main task in the chemistry laboratory of the Ming Academy of Sciences is to turn sulfur into sulfuric acid through various methods.

Of course, the main method of obtaining sulfuric acid in the laboratory is to use green alum and rice vinegar to extract green alum oil, and then chemically react the produced green alum oil with nitrogen to obtain nitric acid.

Both sulfuric acid and nitric acid are used. These two acids are filtered with a platinum mesh, filtered impurities, then placed in a distillation container for heating, and concentrated heating, resulting in concentrated sulfuric acid and concentrated nitric acid.

Song Yingxing's students mixed concentrated sulfuric acid and concentrated nitric acid in a certain proportion, and then soaked the purified cotton in this mixed liquid.

After the soaked cotton is taken out and dried, then carefully grind it into powder.

"It's just that the crushing process is too dangerous, and it explodes if you accidentally." Song Yingxing said.

Zhao Peng asked someone to take some powder, then loaded a little powder into the gun barrel from the muzzle of a self-generated musket into the gun barrel, then put the projectile in it, and then picked up the self-generated musket and pulled the trigger.

With a "bang", the gun sounded, and a light of blue smoke came out from the pot and the gun barrel, instead of the originally thick white smoke, and the power of the musket was much greater than that.

"This kind of launching drug is extremely powerful and will not produce thick and choking smoke, which will affect the vision of the musketeer. However, the production cost of this launching drug is high and cannot be produced in large quantities." Song Yingxing explained to Zhao Peng.

"At present, there is no need to produce in large quantities, so there is no need to produce in large quantities. It only needs to produce a little and provide it to the magic gunmen for use." Zhao Peng nodded.

According to his plan, in the future, all scattered soldiers will have to be replaced with this new type of gunpowder. There are many benefits. On the one hand, there will be no choking smoke that will affect the scattered soldiers' vision. On the other hand, this new type of launcher produces less residue, which will cause less damage to the barrel and is more powerful.

With sulfuric acid and nitric acid, not only new smokeless emitters were produced, but also powerful explosives were produced.

However, Zhao Peng did not specialize in chemical engineering in his previous life, but a soldier. Therefore, he was not familiar with the method of producing safe explosives. He only knew that he could produce nitrogen oil first in an extremely dangerous way, and then used wood chips, algins, etc. to safely treat such very dangerous things, and obtained safe explosives.

Safety explosives are very safe. No matter whether it is a violent collision, a blow, or even a direct ignition of open flames, they will not explode. Only using thunder [mercury] can detonate them.

With sulfuric acid and nitric acid, it is not a very complicated thing to use to make lytic acid [mercury]. With this kind of thing, combined with safety explosives, you can create more powerful flowering shells and various weapons. And after thunder [mercury], you can also directly use a firing rifle.
