Chen Xian plans to try to build a small lead chamber sulfuric acid reaction device according to the data.

The early lead chamber method was relatively simple, that is, the sulfur and saltpeter were calcined together, the high-temperature mixed gas produced by calcination was passed into a lead chamber, and then a small amount of water or water vapor was sprayed in the lead chamber to let the calcined sulfur and sulfur dioxide, nitrous oxide and water produced by saltpeter react to generate sulfuric acid.

Because the production process of the lead chamber method belongs to the gas reaction, the gas volume is large, and the time for the acid mist to condense into a liquid after the reaction is also relatively long.

On the other hand, this reaction is also an exothermic reaction, and in order to be exothermic, the lead chamber must also be made large enough.

In order to solve this problem, people have come up with a method of connecting multiple lead chambers in series, so that the mixed gas can pass through one lead chamber after another, which not only prolongs the reaction time, makes the reaction more sufficient, but also allows multiple lead chambers to share the heat generated by the reaction.

This principle is not too difficult for high school students who have a certain foundation in chemistry to understand, and Chen Xian is easy to understand.

According to this principle, he designed a miniature reaction line in the lead chamber.

Chen Xian first designed a rectangular furnace, which was two meters long, one meter high, and fifty centimeters wide, with round holes ten centimeters thick in the upper half of the furnace wall.

Chen Xian also had a batch of clay vases in the shape of bowling balls fired, with the mouth facing outwards and embedded in a round hole in the furnace wall, and the bottom of the bottles passed through the furnace wall and extended into the inside of the furnace.

When the furnace is lit, the bottom of these vases can be heated; When the jar was filled with a mixture of sulphur and saltpeter, a reactor to produce a mixture of sulphur dioxide and nitrous oxide was successful.

Chen Xian made a pipe out of lead, which was attached to the mouth of the clay vase, and the lead pipe was connected to a thicker lead pipe, two of which were laid along the sides of the furnace to receive the gas mixture produced in the vase.

The gas mixture is connected to several lead drums that are connected in series.

These lead drums are cylindrical in shape with conical ends and are erected on cement bases.

The lead chamber of the lead chamber method sulfuric acid production line was made square at the beginning, but in the later production, it was found that there were many reaction dead corners in the square lead chamber, and the air flow could not flow.

Later, the lead chamber was designed as a thin and tall rectangle......

It took hundreds of years of evolution before the reactor was modified to a cylindrical shape.

Chen Xian's simple design no longer knows how many predecessors are standing on the shoulders of their predecessors.

……

The mixed gas is introduced from the small hole at the lower end of the lead barrel, and the water is poured down from the upper conical tip, and after the water is poured into the lead barrel, it quickly turns into steam under the heating of the high temperature mixed gas, and reacts with the mixed gas to generate sulfuric acid.

Due to the continuous influx of mixed gases and the continuous generation of water vapor, the air pressure in the lead drum increases, and under the action of air pressure, the excess gas passes through a lead pipe in the upper section of the cylinder to the lower air inlet of the next lead drum of the same shape......

The acid mist generated in the lead barrel gradually condenses, lands at the bottom of the lead barrel, and flows through the discharge port at the conical tip of the bottom of the lead barrel into the fine-mouthed clay pot below, where it is collected.

After several commissioning improvements, this miniature lead chamber sulfuric acid production line successfully produced sulfuric acid.

The lead chamber sulfuric acid production line, whether in principle or in terms of process, is not too difficult, with the means mastered by Chen Xian, it is not difficult to build.

However, the production of sulfuric acid alone is not successful, the proportion of raw materials, the amount of spraying water, need to be mastered, in order to produce sulfuric acid with fewer impurities and higher concentration.

Fortunately, the information of the Internet writer has the periodic table and the reaction equation of the lead chamber method.

According to these two things, Chen Xian can easily calculate the proportion of various raw materials and additives, and then through experiments, the ratio of various raw materials can be solidified.

In the end, Chen Xian produced concentrated sulfuric acid with a concentration of about 70 percent.

Seventy percent of the concentrated sulfuric acid can be distilled by heating to obtain 98% concentrated sulfuric acid.

With concentrated sulfuric acid, there is a lack of alcohol with a concentration of more than 95%.

In this day and age, alcohol is not hard to find, but 95% high-strength alcohol cannot exist.

Chen Xian can only increase the concentration of alcohol by distilling it repeatedly; Finally, the last water in the alcohol is sucked through quicklime, and finally a sufficient concentration of alcohol is obtained.

The real difficulty is the seemingly simple experiment of making ether in junior high school class.

The biggest difficulty is not that you don't know the temperature required to make ether, the biggest difficulty is that you don't have a thermometer!

Without a thermometer, this experiment becomes difficult to control.

With the technology that Chen Xian has mastered now, making a thermometer is a complete dream, and he doesn't even have the ability to make glass.

In order to adjust the temperature, he made a furnace that could adjust the height, and controlled the heating temperature by adjusting the height of the furnace and controlling the distance between the heating clay bottle and the heat source.

In order to obtain as stable a heat source as possible, he ordered his subordinates to make briquettes of exactly the same weight, and each time the briquettes were added to the furnace, the furnace should be airtight, and the only vent should be marked with a scale......

He thought of all the methods he could think of to control the experimental environment, and it took more than a month of stupid work to finally make ether stably......

In the process of making sulfuric acid, Chen Xian also repeatedly read some chemical materials he copied from the materials of online writers.

Sulfuric acid is known as the mother of chemical industry because it is the first chemical industrial product to be manufactured, the other two acids in the triacid, can be made from sulfuric acid, soda ash can also be made from sulfuric acid, and soda ash can be used to make caustic soda.

That is to say, based on sulfuric acid, three acids and two alkalis can be manufactured.

With three acids and two alkalis, there is a chemical industry, and with three acids and two alkalis, Chen Xian's soap factory does not have to continue to use plant ash as raw materials.

Sulfuric acid and nitric acid can also be used to make fertilizers......

The production of sulfuric acid seems to have opened a door for Chen Xian all of a sudden......

Just when Chen Xian was concentrating on chemical experiments, a bigger crisis against him was slowly brewing!

……

After this war, Chen Xian hoped to win himself a period of stable development for about a year, so that he could digest the fruits of victory, and at the same time accumulate strength to swallow the entire Yiyuan Plain in one bite.

He felt that his wish was not excessive.

As the leader of the largest green forest in southwest Shandong, Liu Erzu, who even the government was reluctant to provoke, was defeated by himself in one fell swoop, which was enough to deter most of the nearby forces, thus winning a relatively relaxed development environment and opportunities for himself.

But it often backfires.
