Physicochemical properties:
1. Colorless liquid and irritating dour.
2. Melting point 16.6 ℃; boiling point 117.9℃; Flash point : 39 ℃.
3. Solubility water, ethanol, benzene and ethyl ether immiscible, insoluble in carbon disulphide.
Storage:
1. Stored in a cool, ventilated warehouse.
2. Keep away from the fire, heat. The cold season should maintain a temperature higher than 16 DEG C, to prevent solidification. During cold season, temperature should be maintained above 16 DEG C to prevent/avoid solidification.
3. Keep the container sealed. Should be separated from the oxidant and alkali. Mixing should be avoided by all means.
4. Use explosion-proof lighting, ventilation facilities.
5. Mechanical equipment and tools that prohibit the use of easy to produce sparks.
6. Storage areas should be equipped with emergency treatment equipment and suitable housing materials.
Use:
1.Derivative:Mainly used in synthetising acetic anhydride,acetic ether,PTA, VAC/PVA,CA,ethenone,chloroacetic acid,etc

Glacial acetic acid is the earliest and most widely used sour agent in my country. It is a carboxylic acid and belongs to weak acids. However, due to the high content of acetic acid in glacial acetic acid, its volatile acid accounts for a large proportion, so it shows a strong effect. volatility. Glacial acetic acid is an important chemical raw material and is widely used in pharmaceuticals, organic chemicals, organic synthesis, synthetic fibers, polymer chemicals, pesticides, leather, rubber and other industries. Glacial acetic acid is one of the most important organic acids. In organic synthesis, it is mainly used to synthesize monochloroacetic acid, vinyl acetate, amino acids, etc. Glacial acetic acid is a fine chemical product. It also has a broad market in the pharmaceutical industry, food industry and other industries. . Glacial acetic acid is also one of the commonly used varieties as a chemical reagent.
As one of the important organic acids, glacial acetic acid is mainly used in vinyl acetate, acetic anhydride, cellulose acetate, acetate and metal acetate, etc. It is also used as a solvent and raw material in industries such as pesticides, medicines and dyes. , fabric printing and dyeing and rubber industries are widely used. Glacial acetic acid is one of the important organic chemical raw materials, and it occupies an important position in the organic chemical industry. Acetic acid is widely used in synthetic fibers, coatings, medicine, pesticides, food additives, dyeing Weaving and other industries are an important part of the national economy.
Through the detailed introduction of glacial acetic acid in the above article, I believe that all my friends have understood this problem, what is glacial acetic acid, and the important uses and effects of glacial acetic acid. I hope the content of the above article can help you home . I hope the above article will
