Acetic acid, also known as acetic acid, is an organic compound with the chemical formula CH3COOH. It is an organic monobasic acid and is the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.6 ℃ (62 ℉). After solidification, it becomes a colorless crystal. Its aqueous solution is weak acidic and corrosive, strongly corrosive to metals, and steam is irritating to eyes and nose.
Acetic acid is widely distributed in nature, for example, in fruits or vegetable oils, acetic acid mainly exists in the form of esters. Acetic acid exists as free acid in animal tissues, excreta and blood. Many microorganisms can convert different organic substances into acetic acid through fermentation.

The acetic acid industry chain consists of three parts: upstream materials, midstream manufacturing and downstream applications. The upstream materials are mainly methanol, carbon monoxide and ethylene, in which methanol and carbon monoxide are separated from the synthetic gas generated by the reaction of water and anthracite, and ethylene is derived from the thermal cracking of naphtha refined from petroleum; Acetic acid is an important organic chemical raw material, which can derive hundreds of downstream products, such as acetate, vinyl acetate, acetate fiber, acetic anhydride, terephthalic acid (PTA), chloroacetic acid and metal acetate, and is widely used in textile, light industry, chemical industry, medicine, food and other fields. chemwin chemical raw material purchasing and marketing platform provides procurement and sales of acetic acid, glacial acetic acid and other raw materials.
