Questions about alcohol [Copy link]

 

When we talked about alcohol, what is the difference between edible alcohol and industrial alcohol? I searched on Baidu and found that edible alcohol is fermented from grains, and industrial alcohol is extracted from petroleum, but aren't they the same substance? The chemical formula is the same. If industrial alcohol is further refined to a purity of 100%, and edible alcohol is also refined to a purity of 100%, then there is no difference between the two. At this time, if we mix the two kinds of alcohol with water, they are the same and can both be drunk.

Petroleum contains impurities such as methanol and formaldehyde, which are not easy to separate, so it is problematic for people to consume them.

Edible alcohol is fermented food

The main differences are these

Medical alcohol and edible alcohol are the same

You want to say: Maotai is so easy, right? Alcohol is harmful to the human body. But many people like to act cool.

If I can completely separate methanol, formaldehyde and other impurities (of course under ideal conditions), then can I drink the alcohol extracted from petroleum by mixing it with water?

Theoretically, it should be possible, but the problem is that it may not be easy to separate, or the cost will be higher.

After the impurities are completely separated, this wine will probably be much more expensive than Erguotou.

In addition to ethanol, there are also propanol, butanol, pentanol, and even hexanol in wine. In addition to these alcohols, there are other organic substances. Many wines are blended.

It may be more expensive than Moutai, and the technology needs to be improved.

Yes, I think so, because in the end we get the same substance, just through different paths, and the extraction and separation process technology may be more difficult to achieve.

In order to reduce costs, the requirements for impurity content and ingredients of industrial alcohol are much lower than those of edible and medical alcohol. Basically, as long as the ethanol content is sufficient, it will be fine. The preparation method of industrial alcohol is mainly brewing, which is not what the original poster said on Baidu. The cost of chemical synthesis is higher. It is impossible to produce it alone. It only has a certain output as a by-product of other products. Industrial alcohol is mainly brewed with various sugar-containing (sugar in the chemical sense, not in daily life) waste materials as raw materials, only pursuing output and low cost. Methanol is often contained in it, which is highly toxic to the human body. Private brewing may also contain methanol due to poor strains and processes. Private brewing of wine was popular in the past two years, and some people lost their lives for this.

As for purifying industrial alcohol for drinking, that is of course no problem as long as you are willing to pay a high enough price. Commercial production is impossible and not cost-effective at all. Even a fool would not do it.

The synthetic method of preparing alcohol is not to extract it from petroleum. Petroleum does not contain ethanol, and it cannot be directly refined. It needs to go through many intermediate chemical reactions to be finally synthesized. And due to cost issues, the industrial alcohol obtained by this route is a by-product of other chemical products, not specially manufactured for a purpose.

Addendum: Of course, if someone is serious, it is true that intentional manufacturing has occurred, but that is a special case, where coal is used to make liquid fuel for vehicles, tanks, etc. The Germans, who were seriously short of oil at the end of World War II, did this, and other "oil-poor countries" have also studied related technical routes, but under normal market conditions, this will not happen.

Does alcohol have side effects? I think the so-called side effects refer to those that are not handled properly.

As long as there is a conflict of interest, the source of the alcohol is questionable, but we are unable to distinguish

As long as it works, ordinary people won't see any problems. In fact, we don't understand indicators and such. As long as it works within the range, it's fine. It's also something we can't control.

The harm of alcohol to the human body comes from the alcohol itself and has nothing to do with whether it is "cleaned".

What is there to doubt? If you want to drink, there are plenty of regular wineries.

Don't forget, at least with merchandise, you have a choice.
