Read： 828 Time：17months ago Source：Transform the World with Simplicity

Formic acid and glacial acetic acid are common chemicals that are widely used in the chemical industry and other fields. Although they are very similar in name, there are obvious differences in chemical properties and uses. The chemical name of

formic acid is formic acid, and the chemical formula is HCOOH. It is a colorless and transparent liquid with a pungent odor and is mainly used for the preparation of other chemicals. The chemical name of glacial acetic acid is acetic acid, and the chemical formula is CH3COOH. It is a colorless liquid with a pungent smell. It is commonly found in vinegar and is also used as a raw material for organic synthesis and preparation of acetate. Formic acid and glacial acetic acid

also differ in chemical properties. Formic acid is mainly a reducing agent that can react with oxygen to produce carbon dioxide and water, while releasing a lot of heat. Glacial acetic acid, on the other hand, is a weak acid that can neutralize with alkalis to produce salts and water. In addition, glacial acetic acid has a wide range of applications in organic synthesis, such as esterification, ester hydrolysis and the preparation of ester anhydrides.

formic acid and glacial acetic acid also differ in use. Formic acid is commonly used in the preparation of compounds such as oxalate, formate and formic anhydride, and is also used as a deashing agent in the leather and textile industries. The glacial acetic acid is widely used in medicine, pesticides, flavors and fragrances, dyes and coatings and other fields. In addition, glacial acetic acid can also be used in the preparation of food additives and vinegar.

To sum up, although formic acid and glacial acetic acid are similar in name, they have obvious differences in chemical properties and uses. Understanding the difference between them not only helps us to use chemicals correctly in our daily life, but also helps us to better understand the principles and application methods of chemical reactions.
