Indicative formula:CHthreeCOOH,relative molecular masssixty point zero five。
nature:Acetic acid is also called acetic acid(three6%--three8%)、冰醋acid(98%),化學(xué)式CHthreeCOOH, an organic monobasic acid, is the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid with a freezing point of 16.6 ℃ (62 ℉). After solidification, it is a colorless crystal. Its aqueous solution is weakly acidic and corrosive. Steam has irritating effects on eyes and nose. It can react chemically with metal oxides and alkalis.CAS No:64-19-7,It belongs to acidic corrosive goods, No81601。
Purpose:BAcid is one of the important organic chemical raw materials. It plays an important role in the organic chemical industryAcetic acid is widely used in synthetic fiber, coating, medicine, pesticide, food additive, dyeing and weaving and other industries. It is an important part of the national economy
