The weapon tycoon who traveled to Daqin

Shang Wen is a bit discouraged. The reform of taxation will be a shortcut. It can quickly promote the development of the commodity economy. The earlier the development, the more you can provide an opportunity for capital transformation.

Because of the authority of capital challenges.

The current Qin Wang is too superstitious about power. Superstition is so on that the function of ignoring the government. Lisi is also. I do not realize the authority of the government's functions. It is still the original tradition that rely on it.

It is a bit that it feels helpless. Shang Wen cannot describe the current mood. It is too bad. Without the support of taxation, it takes a lot of effort to break through the only line of defense of that layer.

Shang Wen was really annoying about this. It was difficult to fall asleep in bed. Since he couldn't sleep, Shang Wen simply did some experiments.

Recently, there are too many jobs that are busy in production and improvement. It has not opened the door of chemistry for a long time. Now that you can't sleep, you can open this door.

When Shangwen put on a piece of clothes, go out and get some experimental materials.

Shang Wen took out his own notebook. Turn to the page of chemistry. Shang Wen started to create a large amount of raw materials. First of all, it was fierce oil, which was crude oil. Use distillation technology to refine processing crude oil. It is an effective way to obtain some raw materials.

Equipment, such as distillation tower. And, many of the raw materials for production also need to be distilled tower, such as alcohol, acid, alkali, etc.

Shang Wen bit his notebook with his mouth and started to check the recent glass utensils. These are all trials. They are mainly vessels and a small part of the glass catheter. These catheters are made shorter.

Most of them are made by handmade methods. This may be the limits of the current production.

Shang Wen carefully checked these utensils. Because of the immature technical problems, the utensils were made thick and thin. Shang Wen looked at it that these utensils could be broken. However, they could only use it.

The first technology used is fractional technology. The fractional fraction of crude oil is obviously not good. Because of the problem of utensils. Shang Wen thinks that some acid should be processed.

For example, sulfuric acid. Because currently, it does need sulfuric acid, because with a large number of drilling technology to make the barrel. The inner wall of the barrel needs to go through a pickled process. Without this process, the production of the barrel is almost the production of the barrel.

A great restriction. Thinking of the barrel, I don't know what kind of technology is.

This is the process of industrial sulfuric acid. Making sulfur dioxide (boiling furnace)

Burning sulfur or high -temperature treatment of yellow iron ore, and sulfur dioxide S+O? = Live = so?

4FES?+11O? = High temperature = 8so?+2Fe? O?

Contact oxidation to sulfur dioxide (contact room)

2so?+O? = Five oxidation two -钒 catalysis and heating = 2SO? (Reverse reaction)

Rehabilide with 98.3%sulfuric acid

So?+H? So? = H? S? O?

Add water

H? S? O?+H? O = 2H? So?

Purify

The industrial concentrated sulfuric acid can be distilled, and the concentration of 95%to 98%of the concentration of product sulfuric acid.

Another is to make sulfur dioxide (boiling furnace)

Burning sulfur or high -temperature treatment of yellow iron ore, and sulfur dioxide S+O? = Live = so?

4FES?+11O? = High temperature = 8so?+2Fe? O?

Solid sulfur dioxide in water into sulfuric acid.

Sulfuric acid oxidized sulfuric acid. However, these two of them have in common, both based on burning sulfur and sulfur -containing substances.

In fact, it has been found in ancient times to make sulfuric acid through the stem fraud. However, this Tang Dynasty, which was hundreds of years later than the Warring States Period. From 650 to 683 AD (Tang Gaozong), alchemy was lonely.

"Shen Dan Jingjue" Volume 9 records the "Stone Bald Essence Essence", that is, the sulfuric acid is obtained by the dry fierce bile (bile alum).

Cuso? · 5H? O = Heating = Cuso?+5H? O

Cuso? == High temperature == CUO+SO? ↑ ↑

So?+H? O = H? So?

The method adopted by Shang Wen is a simple stem fraud method. There is no way, the appliance is that. Even there is no alcohol lamp.

Shangwen got up to find a lot of food. For fermentation, the weather is cold now. It can only be carried out during the day, or put it on the side of the stove to ferment, that is, to promote the production of bacteria. Shang Wen just tapped all night without sleep.

By combustion, obtain sulfur dioxide, and then use the glass tube. Heating. Oboxes sulfur dioxide. Then dissolve in water, it is worthy of sulfuric acid.

There is no rubber tube, and the sealing is too bad. The experiment almost ended in failure, and the sulfur smell of sulfur made Shang Wen feel suffocating.

A small bottle of sulfuric acid, as for the concentration. Shang Wen has no way to test it.

The sealing effect must be resolved. Otherwise, those who do experiments will die sooner or later.

Shangwen stops making sulfuric acid. These must be restarted until the sealing of the experimental equipment. When this is busy, the temperature is bright. The temperature in the morning is still very low. It is not conducive to the beginning of fermentation. Shangwen can only continue

Place it to the side of the fire and continue fermentation.

Similar experiments of sulfuric acid cannot be performed. Because chemistry has just started. Most of the methods used are stem fraud methods. These methods require good sealing. The solution is to use a large number

I did it according to taking graphite. Now the graphite has risen to the status of strategic resources. The job searching for graphite is expanding on a large scale. However, there are more and more places to use graphite.

I can only use this strategic resource.

For heating equipment, you can only distille alcohol. Do you use a large stove to perform in the experiment?

However, there is a invention that can be carried out, that is, cement. Shang Wen quickly draws the picture on the notebook. In 1824, the British architect Josephaspdin invented the cement and obtained the patent right of Portland cement. He

Use lime and clay as the raw material. After cooperating with a certain proportion, the mature materials are burned in the lime kiln similar to lime, and then made into cement through grinding.

The stone of the building is similar, and is named Portland Cement.

What Shang Wen has to do is this kind of cement. This cement is also called silicate cement. The production is simple and can be made in large quantities.
