Nke mbụ, ọdịdị dị iche
1, ice acetic acid: bụ anhydrous acetic acid, acetic acid bụ otu n'ime ihe ndị dị mkpa organic asịd, organic ogige.
2, acetic acid: bụ organic monic acid, bụ isi ihe na mmanya.
Nke abụọ, àgwà dị iche iche
1, glacial acetic acid: ọ na-agbake n'ime ice na obere okpomọkụ, nke a na-akpọkarị glacial acetic acid. Mgbasa ụda olu n'oge ike siri ike nwere ike ime ka akpa ahụ gbajie.
