Chinese high-quality acetic acid supplier

1、 Basic properties
chemical formula: C2H4O2， The structural formula is CH3COOH.
Physical state: Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.7 ℃. After solidification, it becomes a colorless crystal.
Easy to dissolve in water, ethanol, ether, and carbon tetrachloride.
Odor and Taste: It has a strong pungent odor and a sour taste.
Acidity and alkalinity: Acetic acid is a weak acid in aqueous solution, but it is corrosive, and its vapor has irritating effects on the eyes and nose.

2、 Production and Preparation
The production methods of acetic acid mainly include the following:

Fermentation method: using acetic acid bacteria to oxidize sugars or ethanol in the presence of oxygen to produce acetic acid.
This method has a long history, but its production efficiency is relatively low.
Chemical synthesis methods: including methanol carbonylation method, acetaldehyde oxidation method, etc.
Among them, methanol carbonylation is currently one of the main methods for producing acetic acid in industry, which uses methanol and carbon monoxide to react in the presence of a catalyst to produce acetic acid.

3、 Application Fields
Acetic acid has a wide range of applications in multiple fields:

Food additive: Acetic acid is widely used as a food additive, mainly as a preservative and flavoring agent.
It can inhibit the growth of bacteria and mold, thereby preventing food spoilage, enhancing the acidity of food, and improving its taste.
Chemical raw materials: Acetic acid is an important raw material for many chemical products.
For example, it can be used to manufacture acetate fiber, a fiber widely used in the production of clothing and furniture;
It can also be used to produce vinyl acetate, which is an important plastic raw material.
In addition, acetic acid can also be used to manufacture acetate ester compounds such as ethyl acetate and butyl acetate, which have wide applications in coatings, inks, synthetic leather, and other fields.
Pharmaceutical use: Acetic acid is also used in the pharmaceutical field.
For example, it can be used to manufacture antibiotics such as penicillin and some other drugs such as aspirin.
Cleaning agent: Acetic acid is an effective cleaning agent that can be used to remove various stains.
It can be used to clean copper and copper alloys, removing the oxide layer of copper;
It can also be used to clean glass, remove scale and stains on the glass.
In addition, acetic acid can also be used for household descaling and other purposes.
Agricultural use: Acetic acid is also used in agriculture.
For example, it can be used to manufacture pesticides for the prevention and control of various pests and diseases;
It can also be used to adjust the pH of soil to promote plant growth.
