When it came time to actually extract ether, Marlin found himself overthinking. Why? Because ether is slightly soluble in water......

And Marlin worries about becoming the magazine's sulfuric acid and alcohol, which are both soluble in water. Therefore, wash it with water several times, and the content of sulfuric acid and alcohol can be negligible. Of course, there will also be losses in ether. After all, it is still slightly soluble in water. But that's nothing compared to getting high-quality ether.

However, Marin also thought that this method of multiple washing is only suitable for the extraction of medical ether. After all, that's for people. If it is used in the chemical industry, there are no strict requirements at all. At most once, it can be used in chemical production.

After obtaining the high-purity ether after Marlin's repeated water washing, Leonardo da Vinci, a scientific madman, immediately went to do anesthesia experiments in high spirits. But after a while, Leonardo da Vinci returned in a rage:

"Grand Duke, you lied to me, this thing has no anesthetic effect at all. I covered the sheep's mouth and nose with a damp cloth dipped in ether, but it turned out that there was no anesthesia! ”

Marin thought about it, and suddenly patted his head - Nima, who was fooled by the brain-dead drama. In fact, the dizziness of ether as soon as he covers his mouth and nose should be an exaggerated effect by a screenwriter of liberal arts students who do not understand chemistry. In fact, ether anesthesia takes several minutes to take effect. But the screenwriter who was born as a liberal arts student doesn't understand it, thinking that ether will work as soon as it is used. Just like the person who was shot described on TV, in the TV series, after being shot, the actor who pretended to be a dead body immediately burped. In fact, on the battlefield, people who are shot, as long as they are not shot in the head, will often die for a long time, until the blood is almost gone, and the blood pressure is too low to stop the heart beating, and they will burp. Very few were actually killed on the spot, and most of the dead were seriously wounded and dying for a long time, and then bled to death in great pain......

Leonardo da Vinci listened to Marin's words and went to destroy the sheep again. A few minutes later, Leonardo da Vinci excitedly ran over and said:

"I'm really unconscious, my hands are sore......"

Marin rolled his eyes when he heard this - Nima, in a few minutes, he really covered his mouth and nose completely, and it could also lead to death from lack of oxygen or coma......

However, Leonardo da Vinci was not a fool and naturally did not really suffocate the sheep. He covered the sheep's mouth and nose with a damp cloth dipped in ether, according to Marin. But the damp cloth will not suffocate the sheep, and it can still breathe a little air.

Casually, Leonardo da Vinci beckoned the butcher to kill the sheep, and sure enough, the sheep did not feel it......

Then, Leonardo da Vinci wanted to extend his claws to humans......

"Don't, Ada, human lives are at stake, you can't try randomly! In this case, you go to the prison and find a few murderers who have been sentenced to death to do experiments, and don't test on good people. Be careful not to overdose on the medication and keep a strict record of it. Otherwise, it will endanger people's health! Also, please record the adverse reactions of the human body afterwards under different dosages to avoid excessive ether concentration in the future. ”

"Don't worry, I'm a professional!" Leonardo da Vinci confidently went to an important prison by the coast of the North Sea to hold death row prisoners, and began to devastate the murderers in the prison......

……

After Leonardo da Vinci left, Marin also had some idleness. Leonardo da Vinci did not take all the ether with him, after all, this time Marlin made a lot, enough for a large vat. Leonardo da Vinci took half a barrel and left half a barrel for Marin.

Marlin looked at the chemicals in the lab:

"Ether...... Ether is a good thing! ”

Marin suddenly remembered that the artemisinin of later generations seemed to be made from ether. Because ether is the strongest extractant in the chemical industry.

However, Marlin does not plan to use ether instead of alcohol to extract artemisinin. Why? Because ether is poisonous! Artemisinin is a life-saving drug, if ether remains...... The devil knows if it's medicine or poison...... Marlin is not a chemical engineering major and is afraid that artemisinin from ether will leave ether behind. Therefore, he prefers to use alcohol rather than ether. Anyway, alcohol is actually cheaper. Of course, this is for Marin. Because he used the laboratory method, ether was also prepared by the reaction of concentrated sulfuric acid and alcohol. Obviously, alcohol costs less......

Next, Marlin used ether, an extractant, to play with chemical experiments......

Although he was a liberal arts student in his previous life, Marin also liked chemistry experiments. The preparation and application of ether is precisely the knowledge area of chemistry in secondary schools. If it was college chemistry, he wouldn't understand it yet.

Marlin poured some oil into the ether, and sure enough, he found that the oil was dissolved by the ether. If you pour it into the water, it should float on the water. You can pour ether and dissolve it directly.

Then Marlin found another piece of rosin, which soon dissolved in ether as well. Then he found another piece of beeswax, which also dissolved......

"Beeswax...... Dissolve...... I seem to have something in mind......" Marin thought for a moment......

Seeing the concentrated sulfuric acid in a glass bottle on the side, Marlin remembered what it was......

It turned out that Marin remembered a recipe for smokeless gunpowder......

In his previous life, he was a high school master in all subjects...... No, it's a top student who can't do biology...... Marin still knows a lot about middle school chemistry.

Similarly, as a fan of World War I and World War II among military fans, he has also read a lot of articles about World War I and World War II. Among them, there is an article about gunpowder at that time.

Smokeless gunpowder, for example, is a very important part. Smokeless gunpowder is very important in the history of warfare, and its appearance has made the caliber of firearms continue to shrink, from a large-caliber black powder rifle of about 20 mm to a medium-caliber era of seven or eight millimeters. Later, small-caliber rifles of 5.0 millimeters appeared......

Of course, in modern small-caliber rifles of 5 o'clock caliber, the propellant of the bullet is generally a double-base or three-base propellant. It was a bit complicated, but the technology of the single-base smokeless powder propellant that the French first came up with was very simple.

How simple is it? It is to dissolve dangerous nitrocellulose cotton in ether, and then add paraffin wax as a stabilizer. Then, when the ethanol evaporates, all that remains is the famous "B gunpowder......

Nitrocellulose itself is very dangerous, easily explosive, and its performance is very unstable. Therefore, a tranquilizer must be added before it can be used as a gunpowder propellant.

It should be noted that propellant and explosive are two different concepts. Explosives generally use gunpowder with a high detonation rate, such as TNT, with a detonation rate of 6920 m/s, and nitroglycerin, with a detonation rate of up to 7700 m/s. The devil's Shimose gunpowder (that is, picric acid) has a detonation speed of 7350 m/s. As for black powder, it is said that the detonation velocity is only 500 m/s......

In fact, the detonation velocity of nitrocellulose is also very powerful, with 6300 m/s. However, nitrocellulose is too unsafe to be used directly. However, after adding a tranquilizer, it can be used, but the detonation rate is reduced to about 2000 m/s, which is reduced to the level of propellant. But if you don't deal with it, you can't apply it, otherwise it will explode as soon as it is transported. Before you kill the enemy, you have to kill your own people......

Therefore, treated nitrocellulose cannot be used as a bomb. For example, warheads for missiles, artillery shells and grenades. It's not that it can't be used as a warhead, but it's not powerful enough. People use explosives with a speed of six or seven kilometers per second, and you use propellants as explosives...... It's better to wash and sleep early, so that you can save a dog's life......
