Chapter 152 Sulfurous acid

Although Han Yuan wanted to catch some bison for domestication, the reality gave him a hard blow.

After trying it, he found that he could not catch bison at all for the time being.

This thing is too big when it grows up, and any pothole trap or noose trap is a fart in front of its huge size.

So he can only give up this idea for the time being, and carry the chalcocite ore manually.

These days, in addition to transporting ore, he also built a large laboratory by the river.

At least relatively large for him.

The laboratory as a whole is made of concrete and steel bars. It is nearly three meters high, 20 meters long, and five meters wide.

This laboratory will be the place where all subsequent chemical experiments, including the refining and production of sulfuric acid, will be carried out in it.

Therefore, the South Korean won is simply made bigger, and it is in place at one time, and the province needs to be expanded later.

The walls are concrete and the roof is an inverted V.

In addition, South Korean won still fired some tiles with clay, and then spent some points through the mall to exchange for a batch.

After all, chemical laboratories can no longer use palm trees as roofs like before, and the emissions of many chemical chemicals are toxic and corrosive.

The palm leaves will absorb these emissions. After a long time, various toxic substances will be absorbed in the palm leaves. Staying in them is tantamount to taking chronic poison.

From the design of the laboratory drawings to the completion of the final construction and processing, it took more than ten days.

This is because his system is superior to ordinary people, and all kinds of raw materials are complete.

The huge laboratory is divided into several rooms, each with its own windows, vents, exhaust pipes, liquid drain pipes, lighting placement and other equipment and structures.

It's just that it's still just a prototype, there are no such things as glass, electric lights, and blowers, and it needs to be perfected bit by bit later.

But there is no need to worry about these things, let's get the sulfuric acid out first.

After several months, Won now has a proper arrangement for his work and what he needs to do.

After experiencing the last motor fire incident, he is not in a hurry to do things now, and he is always vigilant when dealing with some things, focusing on his own safety.

After the laboratory was set up, Han Yuan also made a strange looking boiler.

The base and lower half of the boiler are made of steel and are used to burn wood or charcoal.

The boiler cover above is not made of steel, but made of ceramic splicing.

The audience in the live broadcast room were very curious about this weird boiler.

[What is this thing used for?anchor. 】

[Is it a boiler? 】

[For the boiler, can it be made of all iron?Why use ceramics for the upper part? 】

[The anchor has been building a house for ten days, and finally has a new trick. Tell me, what high technology is this time? 】

[Say it's a boiler, but it doesn't look like it, say it's not a boiler, but it's very similar except for the upper part. 】

[I remembered, didn't the anchor say that he was going to make sulfuric acid after making absolute ethanol ten days ago? If I guessed right, this should be something that makes sulfuric acid? 】

After making the boiler, Han Yuan looked up and saw the barrage of inquiries, and explained.

"This weird thing is a tool I made to extract sulfuric acid."

"Because chalcocite is extracted, the resulting sulfur dioxide is corrosive to metals."

"Although dry sulfur dioxide is not very corrosive to metals, it is bound to produce some water vapor during the refining process,"

"Sulfur dioxide is very soluble in water, and when it meets water, it will become sulfurous acid, and sulfurous acid vapor is corrosive to metals."

"So the upper part and the boiler cover can only be made of corrosion-resistant ceramics."

"In addition, there are condensation pipes made of ceramics and glass. The sulfurous acid vapor will condense into water droplets after passing through the pipes, and the excess sulfur dioxide will pass through the pipes and enter the glass container to react with water to form sulfurous acid. .”

"This set of equipment consists of four parts as a whole. The boiler is made of steel, and the upper steamer is made of ceramic splicing."

"One part of the condenser is made of ceramics, and the other part is made of glass."

"The end is the glass container with distilled water."

"Through this set of equipment, I can obtain sulfur dioxide. After dissolving sulfur dioxide in water, I can obtain a sulfurous acid solution, and the sulfurous acid solution can be processed to obtain sulfuric acid."

After a set of theories, the audience in the live broadcast room were dumbfounded.

[It feels so troublesome, I choose to buy directly from a certain treasure. (dog head)]

[It’s so complicated to make something that costs more than ten yuan a bottle. I’m grateful to my parents for living me in the 21st century. 】

[The industrial production of sulfuric acid is actually the same as that of the anchor, they all produce sulfuric acid by calcining sulfur-containing minerals. 】

[How does sulfurous acid become sulfuric acid? 】

[It will naturally turn into sulfuric acid after a period of time in the air. 】

[Is there a big guy who put up the chemical equation? 】

【如您所愿，公式如下：2SO2+2H2O+O2=2H2SO4SO2+H2O=H2SO3】

[What is this writing about?Why can't I understand? 】

【. I can’t understand it either, how to read the 2H2SO4SO2 in the middle? 】

After connecting all the devices, Won checks again.

After confirming that the connection is generally sealed, pour the chalcocite ore that has been collected so hard into the boiler.

A huge amount of chalcocite ore was piled up in the boiler, and he didn't close the lid of the boiler until it was more than half full.

The rest is to carefully splice the glass tube and the ceramic tube flowing out of the ceramic cover together.

After dealing with these, Han Yuan began to add firewood to the bottom of the boiler, and after being ignited, he began to burn chalcocite.

The firewood in the boiler is ignited, baking the chalcocite in the middle layer.

The sulfur dioxide gas produced will rush to the lid of the pot, and then enter the glass container along the pipeline on the pottery lid.

Although some of the sulfur dioxide gas and sulfurous acid vapor may escape due to problems such as insufficient sealing during this process, this is also impossible.

It is already very good to be able to produce sulfuric acid with such a simple equipment under such a simple situation.

After the firewood was completely burned, Han Yuan filled the fire chamber, then got up and walked to the open area on the other side.

There is a huge wooden table with various glass containers filled with water.

Pipes extending from the boiler lead into one of the glass containers, deep into the water.

And as the boiler heated up, the glass tube inside the glass container was constantly bubbling air bubbles.

This means that the gas escapes from the boiler again and travels down the pipes into the water.
