The separation of coal tar is very smooth, and it is nothing more than a process of heating and separation.

Because the future preparation of sulfuric acid even requires a thermometer in all aspects, Zhang Ran and others paid attention to the provincial capital, but they could not find it at all.

However, while Zheng Wanlin and others got the maternal acid, they brought back the urgently needed thermometer. Otherwise, if everything depends entirely on experience, it would be much more troublesome...

Now that you have a thermometer, everything is much simpler. Just pay attention to the temperature changes of coal tar at any time.

Before the temperature reaches 120 degrees, the moisture is first evaporated, and as the moisture evaporates, the temperature of coal tar continues to rise.

When the temperature reaches 120 degrees and is below 170 degrees, light oil can be separated out as a substitute for diesel.

Then there is phenol oil, then naphthalene oil, washing oil, etc., and finally asphalt.

Phenol oil is toxic and extremely harmful, and it is useless for the time being. It is collected and buried and stored together in case of emergency needs.

Naphthalene oil and oil are very useful. Cleaning oil can be used as a neutralizer to increase the extraction amount of chemical substances such as benzene and naphthalene during the flue gas collection process. Naphthalene oil can be directly purified to prepare naphthalene and stored as the raw material for future synthesis of picric acid.

Although everything produced by purifying coal tar is treasured, it is just a odor produced during the purification process, so it will smell bad.

The whole village was filled with the strange smell, which made everyone sniff.

"The light oil was purified for more than 60 kilograms, and the naphthalene oil and benzene etc. were more than 2 kilograms!"

Deng Fang reported to Zhang Ran with a very accomplished look on his face.

"I did a good job, thanks to you, Mr. Deng, or else..."

After praising this, Zhang Ran immediately shut up because Deng Fang didn't take this trick at all. He simply changed the topic and said: "In the future, the coal tar purification or other things should be found specifically, and don't do it in the village - this place is where everyone lives, but no one wants to live in this heavily polluted environment all day long!"

"After all, I'm specializing in chemistry, so you still need to teach these questions?"

Deng Fang hunched: "It's okay to refine coal tar now. When the sulfuric acid preparation process is mature, the pollution to the environment will be even greater. I have already said hello to Secretary Wang and asked him to build a special chemical laboratory for me in Xigou!"

Xigou is several miles away from the village. It is surrounded by mountains and forests. There is no half a piece of land suitable for planting. It is very hidden. The villagers basically don’t go there even if they have nothing to do. It is best to use it as a chemical laboratory.

Zhang Rang thought for a while and said yes, but he was going to go back and say hello to Wang Changtian, listing Xigou and Houshan as military zones, and sending militias to garrison after the laboratory starts construction.

"Coking coal is already being released today. It is estimated that the copper smelting plant will start construction at the latest tomorrow, and the sulfuric acid preparation experiment will be carried out accordingly!"

Deng Fang reminded: "Will you come and have a look?"

Zhang Ran was immediately happy and looked at Deng Fang with a slanted smile and said, "I went over and saw these two knives, wouldn't I cause trouble for you?"

Deng Fan stared at Zhang Ran and gritted his teeth.

Although Deng Fang knew Zhang Ran's nature of the two swords, given that the tower tank method was proposed by Zhang Ran, he believed that since Zhang Ran could propose this method, it was naturally impossible for him to think of it with a slap in his head. He must have seen it somewhere, at least he had heard of it!

Otherwise, he wouldn't have been so confident.

The current situation is that Zhang Ran is full of confidence in these two knives, but he, an expert, is unsure.

If Zhang Ran was by his side, he might be able to provide some suggestions to a greater or lesser extent. He dare not say that it would have a direct impact on the extraction of sulfuric acid. However, in Deng Fang's view, helping him develop his mind may accelerate the process of sulfuric acid preparation.

Okay, with just a little thought, Zhang Ran ridiculed him. How could Deng Fang not be angry and said hatefully: "Do you love to come? I don't believe that without you, Deng Fang can't even get this sulfuric acid!"

After saying that, he left with decay.

"Captain, what happened to you, the one with the surname Deng?"

Kang Ting, who passed by, smiled and said, "Looking at the old man Deng's angrily, why is it so comfortable to squeeze my heart..."

"…We just had a small disagreement on our work, where is it as naughty as you think?"

Zhang Ran gave this guy a blank look and said contempt: "My Deputy Company Commander Kang, you are now a commander and fighter of the Jindong Detachment of the Eighth Route Army. You are not the same as the former chairman's troops. You must always pay attention to your words and deeds, maintain our Eighth Route Army, and maintain the image of our Jindong Detachment. You said that you, Mr. Deng doesn't want his daughter to be with you, that's the truth, so you don't expect people to order well all day long. Are you as for it?"

After being scolded by Zhang Ran like a spurt, Kang Ting quickly surrendered: "Forget it, I can't tell you - I don't believe that when you see Old Man Deng's angry look furious, you don't feel relieved at all?"

Zhang Ran hummed, put on a copy of the captain's fair and strict expression, and said without the boring expression of you: "Comrade Kang Ting, our detachment is about to fight now. I advise you to focus more on the training of the soldiers, rather than being so dark all day long. How is the training going?"

"The recruits are still undergoing some basic training. For the veterans, I asked the platoon leader Shi and platoon leader Wang to go out for training to learn and train the soldiers' night attacks and raid abilities. When they come back, I will prepare to let them conduct sting training!"

Speaking of work, Kang Ting was obviously serious and suggested: "Captain, I suggest that you select a group of soldiers with special skills and conduct special training. For example, those with shooting talent will be specially trained to shoot. Those who have the ability to throw bombs and have a long and accurate bombs, so let them strengthen bomb drop training..."

“What you said makes sense!”

Zhang Ran nodded and expressed his affirmation of Kang Ting's proposal!

Although the combat effectiveness of the detachment is currently very mediocre, if there are several sharpshooters in each platoon, or bomb throwers who are referring to wherever they are, it will undoubtedly greatly improve the team's combat ability.

Just imagine, if several sharpshooters specialize in fighting against enemy machine guns, one shot and one accurate one, or a grenade of the bomber throws the designated place like eyes, it will definitely be a huge blow to the enemy's morale, and it may change the form on the battlefield!

"Then do it as you want. In terms of training, I believe in your vision!"

Zhang Ran nodded, but added a few more points: "Whether it is the special training of sharpshooters or bomb throwers, even if they are talented, I guess they want to get to the level we expect them to reach in a short period of time. The effect of relying solely on strengthening training is probably limited, so I have to think of other moves..."

It was almost dark, Wang Laoguai Shi Yuan and Wang Kai came back with the soldiers who were out to train.

At Kang Ting's request, all the new recruits and veterans gathered together and mixed them again, mixing the main platoon and the reserve platoon into the two new recruits.

After the reorganization was completed, the first row was continued by Shi Yuan, and the preparatory row was adapted into the second row, which continued to be led by Wang Kai, the third row was led by Shouhou, and the fourth row was led by Zhang Baoxin, who had performed outstandingly in the past.

Now there are more than 120 people in four platoons of the detachment, and half of the veterans and new recruits in each platoon are in hopes of playing the role of old and leading new.

In addition to personnel and guns, good guns followed the veterans.

The singles, old sleeves and the like that were eliminated before were distributed to the recruits.

Seeing the four platoons of soldiers lined up with guns waiting for themselves to review, Zhang Ran felt a sense of accomplishment.

Although veterans who play singles with an old sleeve and other singles are disdainful, the new recruits also have many disgusts, but they can't stand the gun in their hands!

Compared to when I was just here, I had a wooden gun on my waist, and there were only three guns for more than a dozen soldiers, one of which was the size of a hunting rifle. Now the team has grown to the point where it has grown!

Not to mention comparing with the time when I just formed the team, even if I compete with many regular Eighth Route Army troops now, except for the main group led by Pu Yuanzhong, Zhang Ran felt that it was probably not necessarily well equipped with the ordinary regular Eighth Route Army troops - there were only a lot of people!

Thinking of this, Zhang Ran walked through the team with his hands in a stylish manner, patted this and looked at that, and couldn't help but hum a little song in his heart - thinking about the beginning, my team had just opened, and more than a dozen people had one or two guns...

That kind of satisfaction is simply not to mention!

But behind Zhang Ran, Wang Laoguai Kang Ting Shi Yuan Wang Kai and others looked depressed and had a bit of a forced smile!

Because they all opposed Zhang Ran's current situation of completely mixing all the veterans and new recruits and breaking up all the equipment, but Zhang Ran insisted and they had no choice!

Zhang Ran wanted the veterans to lead the new recruits to accelerate the growth of the team, and they all understood this feeling.

But the problem is that it is like this that the main platoon and the reserve platoon that have just formed a little combat power will be completely broken up, which is a bit like pulling out the seedlings to encourage growth - especially when you will soon face the situation of fighting with the Cangshui Self-Defense Force, which will seem even more rash!

In their opinion, the best way is to mix the reserve platoon with two new side-by-side arrangements. Do not move the main platoon people and equipment, and ensure the integrity and combat effectiveness of the main platoon as much as possible.

In this way, if there is any unexpected situation during the battle with Cangshui, the main platoon can take over at any time!

With the combat effectiveness and existing equipment of the main platoon, even if there are few people, the Cangshui Self-Defense Forces' products, they believe that even if the main platoon is defeated, it can at least block them!

Now, all the veterans were taken apart, and they were surrounded by raw melon seeds who had never been on the battlefield. Even if the veterans wanted to take it, the new soldiers would probably not be able to hold it. In the end, they might end up with a complete collapse!

But Zhang Ran doesn't think so!

Or he had never been worried at all!

This is a team he has drawn up. Even though he has now expanded nearly half of the recruits, he still firmly believes that the Cangshui Self-Defense Force members will not pose too much threat to him!

If the power is not diluted, the Cangshui Self-Defense Force will be vulnerable in front of the detachment. This battle will not achieve the goal of training the team to the greatest extent!

A Cangshui Self-Defense Force is just an appetizer!
Chapter completed!
