The separation of coal tar is very smooth, it is nothing more than a process of heating and separation, and there is no difficulty.

Because the preparation of sulfuric acid in the future, even all aspects need thermometers, so Zhang Ran and others also pay attention to the provincial capital, but they can't find it at all.

However, Zheng Wanlin and the others brought back the much-needed thermometer by the way while getting the mother acid, otherwise everything would be much more troublesome if everything was based on experience......

Now with a thermometer, it's much easier to keep an eye on the temperature changes in the coal tar.

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

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

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

Phenolic oil is toxic, extremely harmful, and useless for the time being, so it is collected together and buried for storage in case of emergency.

The naphthalene oil washing oil is very useful, the washing oil can be used as a neutralizer to increase the extraction of phenylnaphthalene and other chemicals in the process of collecting flue gas, and the naphthalene oil can be directly purified to prepare naphthalene and stored as a raw material for the synthesis of picric acid in the future.

Although everything produced by purifying coal tar can be described as a treasure, it is just that the smell produced during the purification process is unpleasant.

The whole village was filled with that strange smell that made everyone sniffle.

"More than 60 catties of light oil have been purified, and more than 2 catties of naphthalene oil and benzene have been purified!"

Deng Fang reported to Zhang Ran with a sense of accomplishment.

"It's done well, thanks to Deng Gong, you're here, otherwise ......"

Boasting this, Zhang Ran immediately shut up, because Deng Fang didn't eat this set at all, so he simply changed the topic and said: "In the future, this coal tar purification or something else, let's find a special place, don't do it in the village - after all, this is where everyone lives, but no one wants to live in this heavily polluted environment all day long!" ”

"Anyway, I'm also specialized in chemistry, and I still need you to teach me these questions?"

Deng Fang snorted: "It's okay to refine coal tar now, and when the sulfuric acid preparation process is mature in the future, then the pollution to the environment will be 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, surrounded by mountains and forests, there is no half of the land suitable for planting, and it is very hidden, the people in the village basically do not go to that place if they have nothing to do, and it is the best to use it as a chemical laboratory.

Zhang Rang thought for a while and said yes, but he was going to turn around and say hello to Wang Changtian, and listed Xigou and Houshan as military areas, and sent militia to garrison them after the laboratory started.

"Coking coal is already being produced today, and it is estimated that by tomorrow at the latest, the copper smelting plant will start, and the sulfuric acid preparation experiment will be launched!"

Deng Fang reminded: "When the time comes, do you want to come over and have a look?" ”

Zhang Ran was suddenly happy, squinted at Deng Fang and said with a dry smile: "I'll take a look at these two knives, won't that make trouble for Deng Gong?" ”

Deng Yi stared at Zhang Ran and gritted his teeth.

Although Deng Fang knew the nature of Zhang Ran's two knives, but in view of the fact that this tower and cylinder method was proposed by Zhang Ran, he believed that since Zhang Ran could propose this method, it was naturally impossible for him to come up with it with a pat on his ass, he must have seen it somewhere, at least heard of it!

Otherwise, he couldn't have been so confident.

The current situation is that Zhang Ran's two knives are full of confidence, but he, an expert, has no bottom in his heart.

If Zhang Ran was around, he might be able to provide some suggestions more or less, and he didn't dare to say that it would have a direct impact on the extraction of sulfuric acid, but in Deng Fang's view, helping himself to open up his thinking might be able to accelerate the process of sulfuric acid preparation.

Okay, just such a little thought, was ridiculed by Zhang Ran, how could Deng Fang not be angry, and said hatefully: "If you love to come, I don't believe that without you, I Deng Fang can't make this sulfuric acid!" ”

Say goodbye to decay and go.

"Captain, what happened to your surname Deng?"

Kang Ting, who came in passing by, said with a smile: "Looking at this old man Deng's angry appearance that almost burst his blood vessels, why is it so comfortable in my heart......

“…… We just had a small disagreement about the work, where is it as obscene as you think? ”

Zhang Ran glanced at this guy with contempt and said: "My deputy company commander Kang, you are now the commander and fighter of my Jindong detachment of the Eighth Route Army, not the kind of place where the former chairman of the army was, you must pay attention to your words and deeds at any time, maintain our Eighth Route Army, and maintain the image of our Jindong detachment - you said you, Deng Gong doesn't want his daughter to be with you, that's fair, you don't expect people to be good all day long, are you there?" ”

After being trained by Zhang Ran like a cannonball, Kang Ting hurriedly surrendered: "Forget it, I can't tell you-I don't believe that looking at Old Man Deng's angry appearance of the three corpse gods, you don't feel relieved at all?" ”

Zhang Ran snorted, put on a copy of the captain's fair and strict expression, not as boring as you, and said: "Comrade Kang Ting, our detachment is now about to have a big war, I advise you to put more attention on the training of the soldiers, instead of being so psychologically gloomy all day long, how is the training going?" ”

"The recruits are still doing some basic training, and on the veterans' side, I asked Platoon Commander Shi and Platoon Commander Wang to go out for training, learn to train the soldiers' night attack and raid ability, and when they come back, I will prepare for them to carry out stabbing training!"

Speaking of work, Kang Ting was obviously a little serious, and proposed: "Captain, I propose to select a group of soldiers with special skills for special training, such as those who have shooting talents, they will be specially trained to shoot, and those who are far and accurate in bomb throwing will be specially trained to strengthen their bomb throwing training......

"Makes sense!"

Zhang Ran nodded and affirmed Kang Ting's proposal!

Although the combat effectiveness of the detachment is currently mediocre, if there are a few sharpshooters in each platoon, or bombardiers who shoot anywhere, it will undoubtedly greatly improve the combat ability of the team.

Just imagine, if in battle, a few sharpshooters specialize in hitting the enemy's machine guns, one hit at a time, or a grenade of the bombardier is thrown in the designated place as if it has eyes, it will definitely be a huge blow to the enemy's morale, and maybe it can change the form of the battlefield!

"Then do as you want, in terms of training, I trust your vision!"

Zhang Ran nodded, but added a few more points: "Whether it is the special training of sharpshooters or bombardiers, even if they are talented, it is estimated that if they want them to reach the level we expect them to achieve in a short period of time, relying on intensive training alone, I am afraid that the effect is limited, and I have to think of some other tricks......"

When it was almost dark, Wang Lao and Wang Kai came back with the soldiers who had gone out to practice.

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

After the completion of the reorganization, the first row continued to be led by Shi Yuan, the reserve platoon was reorganized into the second row, which continued to be led by Wang Kai, the third row was led by the thin monkey, and the fourth row was led by Zhang Baoxin, who had outstanding performance before.

At present, there are more than 120 people in the four platoons of the detachment, and each platoon accounts for half of the veterans and new soldiers, hoping to play the role of the old and the new.

In addition to personnel, in terms of firearms, good guns follow the veterans.

Those singles that were eliminated before, old sleeves, etc., were distributed to those recruits.

Looking at the appearance of the soldiers in the four platoons of soldiers lining up with guns on their backs and waiting for their review, Zhang Ran was full of a sense of accomplishment.

Although the veterans of the old guns such as singles and old sleeves are disdainful, and the recruits also have a lot of disgust in their expressions, they can't stand up to having a gun in their hands!

Compared to when I first came, I had a wooden gun in my waist, and more than a dozen soldiers had three guns, including the size of a shotgun, and now the team didn't know how big it was!

Not to mention compared with the time when he just pulled the team, even if he is now compared with many regular troops of the Eighth Route Army, except for the main force led by Pu Yuanzhong, Zhang Ran feels that even if it is an ordinary Eighth Route regular army, it may not be as well equipped as its own detachment - there are many people!

Thinking of these, Zhang Ran walked through the team with his hands behind his back, patting this, looking at that, and couldn't help humming a little song in his heart - thinking that at the beginning, Lao Tzudi's team had just opened, and more than a dozen people came to have one or two guns......

That kind of satisfaction, don't even mention it!

It's just that behind Zhang Ran, Wang Lao, Gui, Kang Ting, Shi Yuan, Wang Kai and others looked depressed, a little forced to laugh!

Because they are all opposed to Zhang Ran's complete mixing of all veterans and recruits and scattering all their equipment, but Zhang Ran insisted, and they had no choice!

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

But the problem is that it is a bit of a stretch to pull out the seedlings and promote the growth of the main platoon and the reserve platoon that has just formed a little combat effectiveness in this way, especially when you think that you will soon face a combat mission with the Kurawai Self-Defense Force!

In their opinion, the best way is to mix the reserve platoon with the two new side-by-side platoons, and keep the personnel and equipment of the main platoon untouched, so as to ensure the integrity and combat effectiveness of the main platoon as much as possible.

In this way, if there is any unexpected situation in the process of fighting Cangshui, then the main platoon can go up at any time!

With the combat effectiveness of the main platoon and the existing equipment, even if they are outnumbered, they believe that even if the main platoon is defeated, at least it can block them!

Now like this, the veterans have all been dismantled, and there are some raw melons and eggs around them who have never been on the battlefield, even if the veterans want to top, I am afraid that the recruits will not be able to withstand it, and in the end it may be a complete collapse!

But Zhang Ran doesn't think so!

Or maybe he didn't worry about it at all!

This is the team he pulled out single-handedly, even if nearly half of the recruits have been expanded now, he still firmly believes that the gang of Cangshui Self-Defense Forces can't pose much of a threat to himself at all!

If the strength is not diluted, the Kurasui Self-Defense Force will be vulnerable in front of the detachment, and this battle will not achieve the goal of training the team to the greatest extent!

A Kurasui Self-Defense Force, that's just an appetizer!

The goal of the detachment has always been a little devil, if the detachment even has to worry about a complete collapse, how will it fight with the little devil in the future?
