As a chemistry doctor, there is a lot of room for displaying your ability in Dakang, a place where the chemical industry is almost zero.

For example, in order to make sulfonamide medicine recently, Liu Mingqi not only made hydrochloric acid, but also made sulfuric acid.

Look!

Sometimes, the manufacturing of chemical agents is matched by a whole industrial development.

With sulfuric acid, many things can be made.

For example, the upgraded version of the soap that Liu Mingqi considers, the low-end version of disinfectant alcohol - boric acid soap.

Boric acid is a kind of anti-corruption thing with disinfection and anti-corruption properties. If it exists in the form of borate and is mixed with soap, it will become boric acid soap with stronger disinfection capabilities.

For small wounds on weekdays, it is enough to use boric acid soap directly.

When there is no disinfection alcohol, large wounds can be temporarily cleaned and disinfected with boric acid soap, which can greatly relieve the symptoms of bleeding and inflammation, and then slowly treat them later.

After all, with the current production and storage methods of disinfectant alcohol, it is definitely impossible for everyone to carry it.

But boric acid soap is OK.

The same is true for the price.

It is impossible for Liu Mingqi to sell disinfectant alcohol infinitely below the cost price just because she wants to help them. This is an absolutely impossible business to last.

Moreover, the poor should not afford to buy what they should not want, and they should not want what they should not want.

However, Liu Mingqi can make boric acid soap at the same price as soap, which can be considered beneficial to the people.

One is used to clean clothes and the body, and the other is used as disinfection on weekdays.

The two uses do not conflict, use which one you want.

It will not be a problem for a boric acid soap weighing half a pound of silver to use it for two or three years if you have no mouth for two or three years - it is impossible for someone to be injured every day, right?

The raw material of boric acid is borax.

Borax is actually one of the medicinal materials.

"Borax is produced in the southwest and has two types of yellow and white. The western ones are white like alum, and the southern ones are yellow like peach gum. They are both refined and formed, like sand. The western ones are soft and remove dirt, kill hardware, and have the same effect as saltpeter, and are in harmony with arsenic."

Traditional Chinese medicine believes that it is non-toxic, bitter, spicy and warm.

In fact, this is not scientific.

Borax is toxic.

If you eat it, you will inevitably get poisoned. If you eat too much, it will be as cool as eating arsenic.

But if it is used to make boride, it is a good disinfection and anti-corruption item.

But this cannot be matched casually.

It must be undergoing chemical reactions.

Compared with borax, boric acid is a purer and more effective disinfectant.

It's not difficult to make boric acid.

After getting the borax, dissolve the borax and filter it, filter out the impurities, then put it into the acid-removing tank and heat it. Add sulfuric acid at about 90 degrees to allow them to react.

After the reaction is completed, after cooling, crystallization, separation and drying, boric acid powder is obtained.

Doesn't it look simple?

Actually, it's still quite difficult.

Not to mention anything else, acid-removing tanks are not easy to make, because sulfuric acid and boric acid are corrosive substances. If not done properly, they will corrode the vessels and will bring harm.

Fortunately, there are already a large number of glass craftsmen in Liu Mingqi's mansion.

They were responsible for making many glass products, test tubes, etc., which had been cultivated long ago.

This is also the final result that Liu Mingqi has been spending money and hiring skilled glass craftsmen.

It is still possible to use large glass jars to make acid-removing jars at present.

Because this kind of mass production is not modern industrial production, the quantity does not need to be so large and the conditions and requirements will not be complicated.

But few families can make large glass round jars that are several meters high and have a diameter of more than three meters.

The other is temperature control.

If no one tells that it is about 90 degrees to react, then it will take thousands of experiments to finally get a reliable result.

Not to mention the money spent here, it takes at least a few months.

This is the benefit of modern people. These crucial knowledge points can be obtained by learning and memorizing without having to experiment one by one.

For this, Liu Mingqi had to make a glass mercury thermometer, which is the type used by modern people, which is much more reliable than a temperature gun.

The mercury thermometer was invented by the Dutchman Valenheit in 1714. It is known for its various advantages such as cheap price, accurate testing, and easy carrying.

But one thing is that if the mercury thermometer is broken, the mercury can easily enter people's bodies through breathing and cause damage.

But this is not a problem for Liu Mingqi.

Do you know Wang Mingyang?

The first thing I wanted to learn from in the Ming Dynasty was the saint who was known as the unity of knowledge and action.

When they were young, they relied on eating mercury to cure their illnesses.

You read that right.

Mercury in ancient times was really used to treat diseases.

It's just a mess!

This is one of the reasons why many Western medicine enthusiasts frequently criticize traditional Chinese medicine.

This approach really lacks scientific basis and has no effect at all. However, this is generally found in some folk remedies, and real Chinese medicine practitioners will not use this.

Besides, that's it.

At the beginning of Western medicine, didn’t it just rely on bloodletting to treat diseases?

If you are sick, you will bleed, if you are sick, you will bleed...

Don’t many kings and queens die here?

Moreover, the treatment of crow x was not something that I had in the Qing Dynasty. At that time, there were also men and women everywhere in Europe. Western medicine also praised this to treat diseases. Why don’t those Western medicine admirers say it?

The topic is turned back.

There is indeed a possibility that mercury is broken, but you can’t ignore the disease and avoid the doctor.

What's more, in ancient times, such glass mercury thermometers were valuable things. No one had ever seen them before. Who would buy them like babies? Who would put them randomly or let children play?

It must be wrapped in layers of silk, thick cloth, cotton, etc., and it will not be taken out until it is used. It must be careful.

Therefore, the possibility of harm is very small, and Liu Mingqi basically won’t consider it.

In fact, the method of making glass mercury thermometers is very simple. Everything is ready-made. And how long the glass tube is and how many scale intervals are all known to Liu Mingqi since he started learning physics and chemistry. He has made several of them himself in modern times.

But when he came to ancient times, he didn't think of this thing for a while.

After making it, Liu Mingqi also specifically told Doctor Zhou about the purpose of the mercury thermometer, which made Doctor Zhou take it for the experiment and called it a living god!

Liu Mingqi told him that the body temperature test is mainly under the armpits.

Between 36 degrees and 37 degrees, the normal body temperature is, and if you exceed 37.3 degrees, the fever is, and when you reach 39 degrees, it is an absolute high fever. You need to deal with it quickly and cannot be delayed at all.

Since there are such accurate standards, ordinary people can do it!

Sometimes it is always a bit inconvenient to take the pulse by simply relying on your hands, and requires strong professional knowledge.

But how many doctors are there like Doctor Zhou Yudian?

How many are spread throughout the world?

Therefore, it is impossible for ordinary doctors to have such skills, and they need a long time of practice and exploration to obtain it.

However, with this mercury thermometer, any doctor can accurately grasp the patient's body temperature and thus use the medicine accurately.

Therefore, ordinary people can measure people's body temperature and know whether they should be sent to see a doctor.

Especially for children, this mercury thermometer is the most effective.

The baby can't speak at all, and the two or three-year-old child cannot express it clearly, so he naturally doesn't know if he has a fever.

Usually when adults discover that many children are already in a state of fever and become fools.

Such examples are everywhere among the people, even wealthy families.

Therefore, Doctor Zhou held the mercury thermometer and shouted that this was a magical object, and praised Liu Mingqi as a living god, but there was no reason.

The topic is a bit too far.

A mercury thermometer is just a tool.

Industrial use is not the same as household use versions, and it needs to be lengthened more than twice. Liu Mingqi sets the bottom line temperature to minus 18 degrees, and the positive one reaches 200 degrees Celsius.

The freezing point of mercury is negative 39 degrees, the boiling point is 356.7 degrees, which is a small meaning of 200 degrees.
