Hand rubbing nuclear fusion live in the wilderness

Chapter 153 Making Ether

At the wooden table, after seeing bubbles coming out of the glass container, Han Yuan pulled the camera and filmed it into the live broadcast room.

"The main component of chalcocite is cuprous sulfide, which forms copper oxide, copper sulfate and sulfur dioxide when heated."

"This is the basic condition for the production of sulfur dioxide from calcined chalcocite."

"And during calcination, I need to judge whether sulfur dioxide has been generated."

"In the absence of test strips or other detection equipment, you can only use the characteristics of sulfur dioxide to smell it on your nose."

"Sulfur dioxide is colorless, but has a pungent odor, which is very stinky."

"So I can use that to tell if the calcined chalcocite has produced sulfur dioxide."

"Sulfur dioxide is poisonous though, so try to be as careful as possible to avoid inhaling too much sulfur dioxide yourself."

As he spoke, he brought his nose closer to the mouth of the glass container about thirty centimeters.

Then he slapped the mouth of the glass container in his direction with his hand, and immediately smelled a faint pungent smell.

This made him know immediately, knowing that the chalcocite ore had begun to decompose sulfur dioxide.

All that's left is to wait.

When the nearby smell is strong and pungent, it means that the sulfurous acid solution in the glass bottle is nearly saturated.

Leaning against the wooden table, Won chatted with the audience while waiting for the water solution to be saturated.

"In fact, the industrial production of sulfuric acid is very mature. It can be done in one step and directly produce sulfuric acid solution, instead of producing sulfurous acid first and then processing it into sulfuric acid like I did."

"But that would require an oxidant 'vanadium pentoxide.'" that oxidizes sulfur dioxide to sulfur trioxide.

"I don't have this kind of thing on hand, so I can only get it through primitive methods."

"Also, didn't I fail to capture those bison before?"

"When the sulfuric acid is prepared, I will have a way."

Hearing this, the audience in the live broadcast room became curious, after all, they had tried various methods before but failed.

[How to catch? 】

【Are you going to splash sulfuric acid? 】

[It should be to use sulfuric acid to make nitric acid, and then make nitrated gunpowder and firearms. With firearms, let alone bison, dinosaurs are not afraid. 】

[The anchor wants to live, live!It's useless to kill it. 】

[Killing meat (dog head), beef is so expensive now. 】

[Can't you expand your thinking?Sulfuric acid, what can sulfuric acid plus the anchor's existing things be used to make?Just think about it a little bit. 】

Looking at the barrage, Han Yuan spat out three words: "Narcotics!"

Hearing the word anesthetic, most of the audience became more curious and asked him how to make it.

Han Yuan smiled, and continued: "After preparing concentrated sulfuric acid, I can use concentrated sulfuric acid and absolute ethanol to prepare ether."

"As for what ether is and what it does, everyone knows."

The bubbles in the glass container kept coming out, and a special smell gradually wafted nearby, which was extremely pungent.

After smelling the smell, Han Yuan immediately moved away from the wooden table to prevent himself from being poisoned by inhaling too much sulfur dioxide.

The chalcocite in the boiler was still calcining, from morning to night, and it took several hours for the Korean won to stop.

Two or three tons of chalcocite were finally collected into ten bottles of sulfurous acid solution.

These sulfurous acid solutions are colorless and transparent, if not for the suffocating smell of sulfur dioxide, they are basically the same as water.

Putting away the glass bottles containing sulfurous acid, Han Yuan said: "This is the end of the experiment, all that remains is to prepare sulfurous acid into sulfuric acid."

"Under normal circumstances, if sulfurous acid is to be converted into sulfuric acid, strong oxidants such as potassium permanganate can be added to it."

"Or just put it in the air and wait for the oxygen in the air to automatically oxidize it into sulfuric acid, but it takes a long time of one or two months."

"I don't have a strong oxidant suitable for sulfurous acid, and I can't wait for it, so I can only think of other ways to speed up the oxidation process."

As he spoke, he quickly put corks on all the glass bottles, and then carefully transferred them to the other side of the vertical water wheel.

There is a blower pipe made before, which is used to increase oxygen in the molten pool, but it was slightly modified by him two days ago.

Not only has the pipe been raised, but the air outlet has been cured with resin.

Carefully carry the sulfurous acid solution and place it under the air outlet of the ventilation duct.

Take the glass tube, put one end into the resin-cured pipe, and put the other end into the sulfurous acid solution.

With the operation of the waterwheel, fresh air continuously enters the sulfurous acid solution through the pipeline.

After disposing of the sulfurous acid solution, Han Won blew a loud whistle.

After a while, in the quiet jungle, two jaguars ran over, one behind the other.

"One treasure, two treasures."

Han Yuan leaned over and rubbed the heads of the two little guys, then said: "Keep an eye on those bottles and don't let other animals touch them, do you understand?"

"Also, don't go there, it's poisonous."

Hearing this, the faces of the two little guys who were excited when they heard the call suddenly drooped.

Aggrieved, he glanced at the Korean won, and then at the bubbling glass bottle not far away.

I thought there was something delicious and fun, but I didn't expect to be arrested to work.

A pitiful appearance, absolutely perfect, provoked the audience in the live broadcast room to yell.

[Ahhh, so cute. 】

[Unscrupulous anchor, actually drove my family's one treasure and two treasures to do things!The kind that doesn't pay wages! 】

[The capitalists will cry when they come. 】

[It's only a few months old, is this child labor?illegal! 】

[The leopard of the poor family has long been in charge (dog head)]

[I also want to be a poor man with a leopard. 】

[One treasure and two treasures: Do you know how much I paid for this family? 】

[How did you train, I also have two Erhas at home, I want to train too. 】

[Upstairs, you should give up, the huskies may still be able to train a bit, and Erha is fine. 】

After the sulfurous acid in the container is converted into dilute sulfuric acid, the rest can be easily disposed of.

Through a set of glass containers, with a thermometer and an alcohol blowtorch, the water in the dilute sulfuric acid can be distilled out by continuous heating.

From the beginning to the end, two or three tons of chalcocite, and finally got a bottle of concentrated sulfuric acid, less than ten kilograms, which shows how difficult it is to obtain sulfuric acid.

After getting the concentrated sulfuric acid, some of the Korean won was diverted and started to make ether.

He needs ether to capture the bison, and then transport chalcocite ore to make sulfuric acid.

Sulfuric acid is very important in chemical industry. Whether it is making plasticizers, making nitric acid, corroding metal parts, or making batteries, sulfuric acid is needed.
