Chapter 847： Accidentally made smokeless gunpowder (middle)

When it started to extract ether, Marin found himself thinking too much. Why? Because ether is slightly soluble in water ...

Marin is concerned about the sulfuric acid and alcohol that become magazines, they are both soluble in water. Therefore, washing it with clean water several times, the content of sulfuric acid and alcohol can be ignored. Of course, there is also a loss of ether. After all, it is slightly soluble in water. But compared to obtaining high-quality ether, this is nothing.

However, Marin also thought that this method of multiple washings is only applicable to the extraction of medical ether. After all, that is for people. If it is used in chemical industry, there are no such strict requirements at all. It can be used for chemical production after washing at most once.

After getting the high-purity ether washed by Marin for many times, Da Vinci, a scientific madman, immediately went on an anesthesia experiment. But after a while, Leonardo came back angrily:

"Duke, you lied to me, this thing has no anesthetic effect. I covered the sheep's nose and nose with a damp cloth soaked in ether, but it turned out not to be anesthetic!"

Marin thought for a while, and then suddenly hit his head-Nima, was fooled by the brain remnant drama. In fact, dizzy as soon as you cover your mouth and nose, it should be the exaggerated effect of writers who do not understand chemistry. In fact, it takes several minutes for ether anesthesia to take effect. But the screenwriter of the liberal arts students didn't understand it. I thought ether would work as soon as it was used. Just like the person who was shot on TV, in the TV series, after being shot, the dragon actor who carried the dead body burped immediately. On the battlefield, people who are shot are often dying for a long time unless they are headshot, until the blood flow is almost the same, the blood pressure is too low and the heart stops beating before they burp. Very few people were killed on the spot, most of them were killed in serious injuries for a long time, and then bleed to death in incomparable pain ...

Da Vinci listened to Marin and destroyed the sheep again. After a few minutes, Da Vinci came running excitedly and said:

"I'm really comatose. I covered my hands sore ..."

Marin rolled his eyes when he heard it—Nima, in a few minutes, she completely covered her mouth and nose, and could also cause hypoxic death or coma ...

However, Da Vinci is not a fool, and naturally will not really suffocate the sheep. According to Marin, he covered the sheep's nose and mouth with a damp cloth moistened with ether. A wet cloth does not suffocate the sheep, but can still breathe a little air.

Randomly, Da Vinci greeted the butcher to kill the sheep. Sure enough, the sheep didn't feel ...

Then, Da Vinci wanted to extend the devil's claw to humans ...

"Do n’t, Ada, you ’re dead, you ca n’t try it! So, you go to prison to find a few murderers who have been sentenced to death. Do not experiment with good people. Note, strictly record the amount of drugs used, thousands Don't overdo it. Otherwise, it will harm people's health! Also, please record the adverse reactions of the human body after different dosages to avoid excessive concentration of ether in the future. "

"Relax, I am professional!" Da Vinci confidently went to an important prison on the coast of the North Sea where he held death row prisoners and began to destroy the murderers in the prison ...

...

After Leonardo left, Marin also had nothing to do. Da Vinci did not take away all the ether, after all, this time Marin made a lot, and there was a big barrel. Leonardo took half a barrel and left half a barrel for Marin.

Marin looked at the chemicals in the laboratory:

"Ether ... ether is a good thing!"

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

However, Marin did not intend to use ether instead of alcohol to extract artemisinin. Why? Because ether is poisonous! Artemisinin is a life-saving drug, if ether remains ... The ghost knows that the drug is poisonous ... Marin is not a chemical major, and is afraid that ether will be left when making artemisinin with ether. Therefore, he preferred 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 reacting concentrated sulfuric acid with alcohol. Obviously, the cost of alcohol is lower ...

Next, Marin used ether as an extractant to play a chemical experiment ...

Although he was a liberal arts student in his previous life, Marin also liked chemical experiments. The preparation and application of ether is precisely the knowledge category of middle school chemistry. If the content of college chemistry, he did not understand.

Marin poured a little oil into the ether, and it turned out that the oil was dissolved by the ether. If it is poured into the water, it should float on the water. It can be poured into ether and dissolved directly.

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

"Beeswax ... dissolve ... I seem to grasp something ..." Marin thought about ...

Seeing the concentrated sulfuric acid in a glass bottle on the edge, Marin remembered ...

It turned out that Marin thought of a smokeless gunpowder formula ...

In the past life, as a middle school full-science tyrant ... No, it's a biological tyrant ... Marin still knows high school chemistry.

Similarly, as an army fan of World War I and World War II, he also read many articles introducing World War II. Among them, there are articles introducing gunpowder at that time.

For example, smokeless gunpowder is a very important part. Smokeless gunpowder is very important in the history of war. Its appearance has caused the caliber of guns to continue to shrink, from a large-caliber black gunpowder rifle of about 20 mm to a medium-caliber era of 78 mm. Later, a small caliber rifle of 5.3mm appeared ...

Of course, in modern small caliber rifles with a few calibers of 5:00, the bullets are usually double-base or triple-base. It's a bit complicated, but the technology of the single-base smokeless gunpowder propelled by the earliest French was very simple.

How easy is it? It is to dissolve dangerous nitrocellulose in ether ~ www.novelhall.com ~ and then add some paraffin as a stabilizer. Then, after the ethanol evaporates, the rest is the famous "B gunpowder" ...

Nitrocellulose itself is very dangerous, easy to explode, and its performance is very unstable. Therefore, a stabilizer must be added before it can be used as a gunpowder propellant.

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

In fact, the blasting speed of nitrocellulose is also very powerful, at 6300m / s. However, nitrocellulose is too unsafe to use directly. But after adding the stabilizer, it can be used, but the detonation speed has dropped to about 2000m / s, which is reduced to the level of propellant. It can't be processed and cannot be applied, otherwise it will explode as soon as it is transported. Before killing the enemy, kill yourself first ...

Therefore, the treated nitrocellulose cannot be used as a bomb. For example, warheads for missiles, shells and grenades. It's not that it can't be used as a warhead, but because it has insufficient power. People use dynamite with a detonation speed of six or seven kilometers per second. You use propellant as an explosive ... Or wash and sleep early, anyway, you can save a dog ...
