Acetic Acid

ACETIC ACID

Acetic acid is primarily used as a raw material for the manufacture of vinyl acetate (VAM). It is used as a reaction promoter in terephthalic acid production and is also a raw material for cellulose acetate, acetate esters, acetic anhydride, chloroacetic acid and a wide range of industrial synthesis.

Acetic acid (synthetic) (СН3СООН) is produced by a method of carbonization from methanol and carbonic oxide on rhodic catalyst, used for the production of salts and esters, acetic anhydride, acetyl chloride, coloring agents, insecticides, as lacquer and paint solvents, and also as latex coagulator.Main technical characteristics

Acetic acid is a flammable liquid. Acetic acid burns the skin on contact. Vapors irritate the mucous coating of respiratory passages. Acetic acid solutions with 30% concentration and stronger causes burns at skin contact.

Transportation

Acetic acid is transported in clean rail tank cars with stainless steel inside surface, equipped with overhead discharge and self-heated system or in “thermos” -typed rail tank cars by railway and in special chemicals vessels with stainless steel tanks by sea.

Storage
