Chapter 67 Experiments

Some things are really difficult to describe in words. Things on the battlefield are always relatively straightforward, but things surrounding the battlefield are not so straightforward. Instead, they are a bit troublesome. Hancheng is now working on something new, the most important one

The thing is aspirin, an antipyretic and analgesic drug. It is relatively not difficult to obtain the raw materials.

Salicylic acid is found in willow branches, and it will be enough to extract it directly. The difficulty may be acetic anhydride, which is not so easy to make. After living for twenty or thirty years in later generations, there is no saying that it is slow to obtain pure raw materials.

It is slow to refine. Whether it can be made concretely depends on whether it can solve the problem.

"Smash the glass bottles for me. I'm going to burn a big one."

There is no retort used in the laboratory here, so I can only burn one by myself. As for other things, I can use wood to replace it, which will be cheaper. But even so, just based on paper calculations

, the cost has reached 3,000 yuan.

"The cost is too high, and I feel unsure."

Han Cheng said to the political commissar next to him. The political commissar shook his head, but did not refute Han Cheng's words.

"The price is indeed high, but as long as we can make one, even the salicylic acid you mentioned, it will be a pretty good thing for our hospital."

It is basically normal for hospitals to be short of drugs. Most of the drugs in the country are imported. This may be an exaggeration. It should be said that 90% of the drugs are imported.

"Such a thing is actually difficult to make. Even if it could be made, the quantity would not be too large."

Han Cheng is not pessimistic. Synthetic drugs like this cannot be used without a certain level. If any link is wrong, people will die.

"It's better than nothing. Who can say clearly what will happen in the future?"

Now Hancheng is busy making acid. If he didn't rely on the system and didn't have a deep knowledge of chemistry, he wouldn't be able to think about it. With sulfuric acid, things will be easier to handle, and acetic anhydride won't be that difficult either.

.

The structures have been set up, and all that's left is to find opportunities to turn these things into physical objects. To be honest, some things are very useful. It's just that for the current army, not many people can use such tools, which are simple and crude.

environment to produce chemical raw materials that are more in line with specifications.

"Then I won't bother you anymore. The rest depends on whether you can produce enough finished products."

The main reason for such undifferentiated trust is because of their previous success. Without previous events, they would be much more cautious about everything.

"Okay, walk slowly, political commissar."

The regiment sees this matter as a serious matter. During this period, the troops suffered relatively heavy losses, but now there are not many medicines in the hospital. Asking for help from other parties has not received any response. The shirk is for sure, and medicines are more in demand than bullets.

Things and bullets may give you a price, but medicines may not even give you a price.

"Oh, how can it really be that easy to do?"

Now that Hancheng has produced some sulfuric acid, it is time to collect materials and make smokeless gunpowder first. If this thing is not made, the smoke caused by black gunpowder will leave a big target for the enemy.

Han Cheng entered the studio with the sulfuric acid in his hand and began to synthesize the required smokeless gunpowder. The preparation of smokeless gunpowder is more complicated and its storage is also required. At this time, the weight of the bullet has changed somewhat.

It’s no longer the kind full of black powder.

Regarding the matter of smokeless gunpowder, other people have complained about it for a day or two. Because black powder is used, the gun must be cleaned after every battle.

The last thing the soldiers wanted to do was to clean their guns because it was too troublesome. They knew that they were using black powder, but they didn’t know where they found out about it. Smokeless powder didn’t require so many cleanings, so they just

Start responding to the battalion commander.

The battalion commander then reported to Hancheng that there was nothing he could do, and he couldn't stand what he said was right. The smokeless gunpowder did indeed leave very little residue, and there was no smoke from black powder.

Han Cheng didn't want to bother, so he just reported it directly. After the report was completed, he didn't know who said he built this tank to make smokeless gunpowder, so the responsibility fell on Han Cheng's head again.

"I provoked someone!"

The regiment commander is excited. He is going to make smokeless gunpowder. The arsenal of his regiment is going to make a fortune. If nothing else, besides the Kuomintang District and the Taiyuan arsenal, there are several places where smokeless gunpowder can be made.

What about the gunpowder? The gunpowder has to come in from other armies’ repair shops or even military factories for secondary reloading.

It is not a forced order. They also know that this thing cannot be forced. If it is easy to do, why can't it be done when there are so many capable people in the base? The regiment leader just told Han Cheng that the regiment would try its best to support it, but in Han Cheng's view,

Saying it basically means just do it.

Having said that, if you don't have any more points, it won't work. I can only bite the bullet and go ahead. I've tried every possible method and every idea I can think of. I don't even know about the sulfuric acid in the glass bottle.

How many things can be made? Who knows what the final result will be now. If we cannot make a double-base propellant, I am afraid we can only make a single-base propellant.

"We have made some trial production of nitric acid, so let's do it first."

Han Cheng looked at the liquid in another wine bottle, but there was nothing he could do. Everything had to be put in wine bottles. The funnels in the laboratory were all made from a light bulb, which was a huge savings, but there was nothing he could do. Some

You can't buy things if you have money, because they are not produced domestically.

"Put on my mask, put on my bottle-bottom glasses."

This is considered an experimental outfit. The bottom of the bottle is relatively thick. If something happens, the bottom of the bottle can block your eyes. There are actually many glass wine bottles. After drinking, these bottles will remain

At home, sometimes I use it to make wine again, and sometimes I just use it to add oil, salt, sauce and vinegar.

Han Cheng now knows what he looks like without looking at it. Such a wasteland-style scientist holds a beaker made of a wine bottle in his hand. It is actually a bottle with the bottle cut in the middle.

Anyway, the appearance is ready. Whether these things can be transformed into physical objects depends on luck and operation. Han Cheng carefully poured out the refined chemicals, and it took him an entire night just to get the bottle. In short, the transformation efficiency was very high.

Low.

"The amount looks about the same."

Han Cheng looked at the little thing in the beaker, and then started to put another thing in. The color of the liquid immediately changed, and a violent reaction began.

"Oh my God! Is this a success or a failure?"

Anyway, just follow the steps step by step in the experiment. It is not easy to make two or two things.
