If the liquid is used in the same way and the heating temperature is controlled once or twice, the concentration of alcohol will become higher and higher. However, the maximum is not more than 95%, and this principle is called constant boiling.

This roughly means that there is also a part of the non-ethanol substance that is also boiled and cooled with the ethanol, and it cannot be removed no matter how distilled. To achieve the purity of anhydrous alcohol, constant boiling distillation must be carried out by chemical methods.

But for now, Hong Tao doesn't need such pure alcohol, and technically can't do it, and it's very good to be able to purify it to 95%. What can I do with this thing? There are many uses.

It can be diluted to about 75% as a medical alcohol treatment for trauma, in ancient times when there was no effective disinfection method, it was likely to save a life by wiping the wound with an alcohol cotton ball.

In particular, emergency medical treatment on the battlefield is a miracle cure, and many injured soldiers are not fatally wounded, but because of complications from infection, they are either dead or disabled.

If we can revive these soldiers, then they will be elite soldiers who have seen blood, life and death, and they are a hundred times stronger than any soldier who has only trained and never fought a war.

It can also be used to make perfumes, and the Song people have used pressing, preliminary distillation to extract flavors from flowers, and use them to make various incense medicines, but they have not yet realized that there are such magical things in the liquor they drink every day.

The blending of flavoring agent and alcohol is a new commodity that can make a lot of money, and this industry is a complete industrial chain, from planting flowers to picking, processing, as well as the production and blending of alcohol, perfume packaging, sales, etc., how many jobs and profits will be created? Count your fingers.

And perfume can not only meet domestic needs, it is also a very suitable export product. As long as the secret of alcohol is kept, it will be very, very difficult for others to imitate for many years, and they can use this low-cost and high-value-added bait to pit foreigners.

All that was exported was a small bottle of flowers and an alcohol mixture, and in exchange for real money, livestock, cattle and horses, spices and grains.

How many soldiers can be fed, how many weapons can be made, and how many domestic contradictions can be bridged? I'm afraid it's not enough to add all the toes.

Of course, alcohol itself is a good fuel and organic solvent, and its properties can be used for many purposes. However, these are still too early, with the current grain production, if everyone burns the alcohol stove, the food in the whole of Asia will not be enough for the people of the Song Dynasty to burn, and they will all starve to death in the end.

On this day, no one was allowed to enter the back garden of the Horse Mansion except for a group of accomplices of the Horse, and everywhere was enveloped by the strong smell of alcohol, and barrels of sake lees were brought in through the back door and placed in a cauldron to be heated, and a distillation kettle like a hanging bell was buckled on it.

The experiment of distilling alcohol with low-alcohol liquor Wang Datou has already done it, and it is quite successful, and Hong Tao does not want to repeat it. If he and Wang Datou are at the same level, they can only use low-alcohol wine to refine Datou water, how can they show their superior skills.

So Wang Datou was sent out to buy sake lees in the main store in the city, and then shipped back as a raw material for refining alcohol. Now Wang Datou was dumbfounded, there are dozens of main shops in the city that can make wine, and the daily production of sake lees is countless, and the price is much cheaper than wine, and it is obviously more cost-effective to refine Datou water with sake lees. From this, it was concluded that the horses were indeed clever, and the design of the shochu pot did not originate from the imperial palace.

When it was time to eat in the evening, everyone from Lian'er to Zhu Bajin was Guan Gong's face, and the princess was no exception. She went to the back garden just out of curiosity to take a look, and was grabbed by the colt and pinched her neck and poured a mouthful of bitter and spicy things, called Datou Shui!

Wang Datou learned the lesson of the morning and let him stop drinking, but he still didn't escape. Everyone who drank a lot of water would come and kick him viciously, just to relieve his hatred.

It's so bad to drink, it's not only uncomfortable in your mouth, but also in your stomach. The worst thing is that it makes people dizzy, which is more uncomfortable than drinking a dime of wine.

"This thing is poisonous and can frighten the soul, and you must not taste it again after this lesson! The production method should also be kept strictly confidential, and if outsiders know about it, you will not be able to escape it. Don't think that there is no good way for the Horse Mansion to take you, this thing is unique to the official family, and it should be the Imperial City Division who will come to trouble you when the time comes! ”

Of course, Hong Tao would not tell them that this was a side effect of alcohol, but instead resorted to a mythical treatment, saying that it was a spell, and warned everyone not to try it lightly.

In Hong Tao's view, there is no essential difference between high alcohol and flower cream, both are addictive things, and the more addictive and slow it is, the greater the addiction and the deeper the harm.

There is no need to prove this, the liquor industry in later generations is an important source of filling the treasury as a high-tax industry, and the harm caused by this is also obvious to all, and crimes, accidents, family and other inquiries will consume a lot of social resources.

It's okay to use it as a medicine or make perfumes, but don't develop the liquor industry too early. Although that thing is also a big rake for money, the side effects are bigger than the flower cream.

Flower cream can be banned by the severe punishment calendar, and its poison is relatively easy to recognize. But alcohol addiction is different, you can't say that whoever drinks will cut off someone's head, and there is no difference between getting drunk with a low degree of alcohol and being drunk with a high degree of alcohol.

You can't just take someone's home because you grow grain and fruit trees, but the raw materials for brewing are these things. In an era when agriculture was not very developed, brewing high-grade sake would consume a lot of food, and it would do more harm than good. To enjoy, drink some rice wine, fruit wine, and wine.

As for using liquor as a commodity to export to the northern peoples, in Hong Tao's view, it is not a good way. This thing is very addictive and too expensive, and it is not as direct as the flower cream in terms of destructive power and speed of making money. The most important thing is that it cannot be effectively banned from circulating in the country, and there are too many sources of raw materials, and no one can stop it once it becomes popular.

But if it is not made, it will not be done, and there will be many industries in the future that will use ethanol with relatively high purity, such as purifying anhydrous ethanol and anhydrous ether, which is the only way to passivate nitrocellulose. Sooner or later, firearms will have to be put on the table, and if we can't train talents in this area early, it will be impossible for Hong Tao to get out of all these industries by relying on himself alone.

This may have been the situation of the Curies in the first place, their discoveries could be used as a realm of peace, but they could also be turned into demons, and if they had known the consequences in advance, they would have tried to prevent this from happening. Of course, just procrastination is the same thing as what Hong Tao is currently doing, and it is impossible to completely cut it off, and no one can stop the progress of the entire human society.
