Chapter 155 Explosive Factory

While Li Di was tossing his gun cotton, the chemical engineering team designed and built a large courtyard in a place far away from the buildings and residential areas on the bank of Wenlanhe.

The open space within 200 meters in diameter centered on the courtyard was cleared and no grass grew. The ground was repeatedly rolled with loess, lime, and fine sand. Even the stones were all picked out, and the road was paved with bricks.Two barbed wire fences were erected around it, and there were pieces of wooden boards painted with hideous black skulls and large fireproof signs hanging on them.

This is the pharmaceutical factory of the chemical group.In order to implement fire prevention and anti-collision, the construction team took great pains to adopt cement and brick and tile structures. The roof does not use wooden beams and columns, but uses brick arch structures.The whole house does not use iron, wood, or even stones to prevent any sparks and combustion.

According to the suggestion of several drug enthusiasts, instead of paving bricks on the floor of the production workshop, a layer of river sand was laid to absorb any acid, alkali and drugs that might fall.

The structure of the house is also very special. The production workshop in the middle not only has windows on the north and south sides for ventilation, but also opens doors from east to west. Next to the door is a trench deep for one person, which is paved with fine sand.This thing is an escape ditch. In case of any uncontrollable chemical reaction, you can use this to escape-the premise is that everyone's reaction is fast enough and their legs and feet are flexible enough.

These two escape ditches brought a dignified atmosphere to the chemical group.Just as the dream of many people in the mechanical team is to build guns, very few people who engage in chemistry do not yearn for zha medicine.Many people secretly made all kinds of zha drugs when they were in the laboratory, but in this crude environment, how sure are they?

A group of people sat in the middle of the barbed wire hanging with skulls, discussing the direction of the zha drug.

"Do you know what we are going to do?" Ji Sixui looked at the group of people in front of him.

"Make medicine, we have been waiting for this day for several months."

"Everyone must be mentally prepared to die and be disabled!" Ji Sixui said viciously, "Now it's not a trick of making black fire and adding some batter."

"You crow's mouth!" Ji Situi was smashed into a pile of mud and clods, and slipped to the side in desperation.

In addition to the people from the chemical engineering team and the mechanical team, Li Di, who suffered a tragic failure with nitrocellulose, also participated in this pharmaceutical meeting—he was unwilling to accept the failure of his nitrocellulose.

"I just don't understand why nitrocellulose can't be done!" He was extremely annoyed, thinking that it was something that could be done easily.

"Chemistry is a very delicate job, so it's not that simple." Ji Situi said, "Your craftsmanship is problematic, and you still lack some of the most basic equipment."

"If we get all the equipment together, nitrocellulose is nothing." Ye Yuming said.He is a small civil servant, but he has studied chemistry and has a good research on mines and blasting.

"Well, if we can make a bigger centrifuge." Ji Sixui thought that everyone knew about it, but the problem was where to get this thing besides a small centrifuge in the laboratory.

Without a centrifuge, it is difficult for nitrocellulose to completely remove the free acid in the cotton fiber.Nitrocellulose can become extremely unstable in practical use, and the Austrian army suffered from it in the 19th century.

"I still need the help of the industrial department." Xu Yingjie said, he is very obsessed with chemical products, especially likes to prepare various chemical agents, and belongs to the kind of experimental maniac who loves to do things.

"It's difficult," Wang Luobin shook his head, "Our prime mover isn't good enough."

"How about **?" Li Yunxing made a suggestion. He also recently transferred from the military group to the artillery group.

It is not difficult to make glycerin with nitric acid in hand, and there is a steady stream of ice cubes in Fengchenglun cold storage to cool down, so it should be relatively safe to manufacture.

"I have a recipe." Ye Yuming was enthusiastic, "I made it myself in the laboratory—"

Everyone gasped, there are really bold and bold people in this world. **Although it is known for its simple manufacture, it was often manufactured and used by various terrorists and revolutionaries in the 19th and early 20th centuries, but more martyrs died in the manufacturing process than the police.

Ye Yuming's formula is:

(1) Add *mL distilled water to *mL beaker;

(2) Prepare a large amount of ice-salt mixture and place it in the water tank.

(3) Put the *mL beaker into the water tank, inject *mL concentrated nitric acid, and cool down to below *°C.

(4) Slowly add *mL concentrated sulfuric acid, mix evenly, and cool the mixture to a high degree.

(5) Slowly add glycerin with a dropper, about one drop per second, and pay close attention to the temperature, keep it below the temperature; stop when there is an obvious glycerin layer on the surface of the mixed acid solution (approximately add glycerin*mL).

(6) Stir slowly for about [-] minute, and keep it at a high temperature and low temperature.

(7) Pour the mixture into the beaker in step [-], at this time, the liquid will settle to the bottom of the beaker.

(8) Use litmus paper to detect the acid until it does not show acidity.

If there is sodium carbonate, sodium carbonate can also be added to enhance the stability of the drug.

"I'm willing to try it a little bit," Ye Yuming said confidently, "I've done it once or twice, and I'm quite experienced. These things are not rare, and the equipment is also available. If it is feasible, it can be manufactured on a large scale."

"This method will blow you to the sky." Xu Yingjie repeatedly shook his head, "The glycerin used in the laboratory is analytically pure. The glycerin we can produce now can only be saponification method, which contains saturated fatty acid salts. It will first react with the mixed acid to release heat, and you may not be able to stop it in time with the ice-salt mixture. The last thing is——Boom!"

"Oh, I didn't think of that question."

Xu Yingjie said: "I think the development direction of the chemical industry, from high to low, is: 1. Nitrocellulose, gun power multiplier, other guns can't do it. 2. Synthetic ammonia, this can be done as soon as our synthetic ammonia factory is completed. .3. Picric acid, impact-resistant, powerful zha that can be fired with nitrocellulose. **It’s useless, it can only hold zha kits, grenades, etc., its power is not obviously better than picric acid, and its stability too poor."

"Synthetic ammonia is not a problem. Once the factory is completed, it can be completed, but picric acid is too difficult." Ji Situi categorically denied, "The process of producing phenol may be possible in 10 years. The conditions of 13 atmospheres alone will not work."

"It is not necessary to use benzene to extract phenol from coal tar. Phenol is originally a product of coal coking."

"The efficiency of this process is not very good. If we must make picric acid, our coal coking plant will be able to produce phenol as soon as it is put into operation. If we don't mind the low output, we will be able to do so at that time. The problem is that the military team can't wait now." Ji Situ said helplessly. Spread your hands.

"Then there is only black fire medicine." Xu Yingjie said, "If someone is not afraid of death, they can also try **."

In the end, no matter whether it is fenugreek or picric acid, we have to wait for the chemical plant to start production.Right now, it is certain that black powder can be manufactured, and they are confident enough to produce fine-grained black powder, including propellants and explosives, whose quality far exceeds that of this era.Even the supply of saltpeter is not too difficult. Even if there is no supply of saltpeter from Guangzhou, a certain amount of saltpeter can be obtained by using the pile nitrate method.According to the inquired information, in 1959, a certain county built a black yao manufacturing plant for quarrying. It does not rely on the import of saltpeter, but only relies on the collection of soil nitrate and the pile nitrate method of the whole county to achieve an annual output of black yao. 50 levels of medicines.If you control Lingao county government, you can still produce 20 to 30 tons of black fire medicine a year.

Lin Shenhe said: "The most important thing is safety and stability. It doesn't matter if you replace it with a black gun, but we still lack a cap. If there is no cap, the industrial sector can only make smoothbore guns."

Thunderbolt is necessary to make flash caps.Mercury is the primary explosive.The cannonballs and grenades of the black gun are okay, but the miniature rifle of the traverser must have a cap,

The process of mercury mercury is not complicated: simply speaking, it is the product of dissolving mercury in nitric acid, mixing it with alcohol, and finally reacting.

Mercury is not an easy thing to get. The Guangzhou advance station even bought mercury belts and cinnabar, but they only got back about ten kilograms of mercury. This has already sold out all the pharmacies in Guangzhou.The chemical industry group also considered making thunder silver, at least silver is much more than mercury, and silver is non-toxic, but thunder silver is more sensitive than mercury.Or mercury is safer.

Making thunder mercury requires high-purity alcohol, and there is no technical difficulty in making alcohol. However, the potato crops have not yet come down, and it is a bit wasteful to use rice to make alcohol. The commercial department bought a batch of the strongest shochu from Qiongshan County through the purchaser Lin Quanan. Back, the chemical engineering team designed and manufactured a wooden and tin structure distiller for secondary distillation. The first distilled liquor was distilled into crude alcohol, and then distilled again, so that the alcohol with a concentration of 96% was obtained. , the remaining about 3% of the residue is fusel oil, which can be used as a raw material for penicillin.Of course it is too early to talk about penicillin.

Xu Yingjie is responsible for the trial production.This person who likes to fiddle with all kinds of disgusting chemicals has read his chemical manual countless times, and read the process flow copied from the database over and over again until he completely remembers the whole process.

The manufacture of pyrotechnic products is the most dangerous part of the entire military chemical industry system. Even in a modern factory environment, danger is always accompanied by producers, not to mention those who are going to use crude equipment to manufacture by local methods.

Although mercury itself is sensitive and dangerous, it reacts in a humid environment and is relatively safe.However, for the first-time traveler who is playing with pyrotechnics, it is bragging not to be afraid.For safety reasons, everyone exited the laboratory for the reaction.Just leave him alone in it.The military team originally wanted to sponsor a set of explosion-proof suits, but it would not be easy to work after wearing them, so they had to give up.

Xu Yingjie first puts * parts of pure mercury into a ceramic pot, then adds * kg of nitric acid, and then heats it to *~* °C in a hot water bath. During the heating process, it should oscillate from time to time, and the mercury will slowly dissolve. , After about 40 minutes, Xu Yingjie got a jar of green mercury nitrate solution.

After the mercuric nitrate is made, preheat *kg of alcohol with *% purity to *～*℃, and then add mercuric nitrate into the alcohol.Here the temperature control is very important.Xu Yingjie paid attention to the display of the thermometer all the time.

The reaction started as soon as the alcohol was poured in, and the mercury nitrate solution began to boil. After all the alcohol was poured in, shake it a little. At this time, he saw that the temperature of the thermometer had risen to *°C.Indicates that the reaction was successful.After the temperature slowly reached *℃, the reaction tank was filled with thick white smoke. Xu Yingjie knew that the preparation was basically successful. If there was no red smoke, he could just quit and rest and wait for the reaction to complete.He checked his watch and noted the time when the reaction started.

He checked the glass condenser above the tank to make sure it was working properly.This thing is used to collect the smoke during the reaction.The dense smoke generated during the reaction is not only toxic and flammable, but once condensed in the reactor, it will affect the output and quality of erythromer.

The people in the chemical engineering group stared at the courtyard door from a distance, and everyone applauded when they saw him come out, and Xu Yingjie posed a few poses very cooperatively.

An hour and a half later, when they walked in again, the reaction had completely stopped, and a layer of gray granular matter was condensed on the bottom of the reactor, a bit like gray sand.

Xu Yingjie carefully collected the wet mercury, wrapped it in cotton cloth, and squeezed out the water with a manual compressor to make the moisture content below 5%.Under normal circumstances, it takes 10 to 15 hours for thormercury to be dried with warm air in a special drying room.Now there is no such condition, so it can only be dried naturally.
