I-Acetic acid iyi-carboxylic acid egcwele equkethe ama-athomu amabili ekhabhoni futhi iyi-derivative ebalulekile equkethe umoya-mpilo yama-hydrocarbon. Ifomula yayo yama-molecule yi-C₂H₄O₂, enefomula yesakhiwo i-CH₃COOH, futhi iqembu layo elisebenzayo yiqembu le-carboxyl. Njengengxenye eyinhloko yeviniga, i-glacial acetic acid yaziwa nangokuthi i-acetic acid. Isibonelo, ikhona ngokuyinhloko ngesimo sama-esters ezithelweni noma emafutheni emifino, kuyilapho ezicutshini zezilwane, ekukhishweni, nasegazini, i-glacial acetic acid ikhona njenge-free acid. Iviniga evamile iqukethe i-acetic acid engu-3% kuya ku-5%.

Idatha ingatholakala eminyakeni engaphezu kwengu-20 yesipiliyoni njengomthengisi we-glacial acetic acid. Chofoza lapha ukuze uthole isilinganiso.
