acetic acid properties tagged posts

~ also known as Ethanoic acid; 64-19-7; Ethylic acid; Acetic acid, glacial; Methanecarboxylic acid etc. is the second simplest carboxylic acid (after methanoic acid) and is a weak monoprotic acid. Global demand for acetic acid is about 6.5 million metric tons per year (Mt/a), of which ~1.5 Mt/a is met by recycling; the rest made from methanol.

Chemical structure:  CH₃COOH (CH₃CO₂H, C₂H₄O₂). It has a methyl group attached to a carboxyl group.

Properties: hygroscopic, corrosive liquid with a vinegar-like odor. At physiological pHs, acetic acid is usually fully ionised to acetate.

Production: 

Acetic acid is produced industrially both synthetically and by bacterial fermentation

a) Methanol carbonylation (approximately 75% of acetic acid in the chemical industry): Metha...
