Acetic acid, nke a makwaara dị ka acetic acid (36%-38%), glacial acetic acid (98%), usoro kemịkalụ CH3COOH, bụ organic monic acid, bụ isi ihe na-emepụta mmanya. Acetic acid dị ọcha (glacial acetic acid) bụ hygroscopic siri ike na-enweghị ụcha nke nwere ebe na-ekpo ọkụ nke 16.6 Celsius C (62 Celsius F) wee ghọọ kristal na-enweghị ụcha mgbe emechara ya. Ngwọta mmiri ya na-adịghị ike acidic na erosive, na uzuoku na-ewe iwe na anya na imi.
Glacial acetic acid (ihe dị ọcha), ntụgharị acetic acid anhydrous, ngwakọta organic. Ọ na-agbake n'ime ice na obere okpomọkụ ma a na-akpọkarị glacial acetic acid. Mgbasa ụda olu n'oge ike siri ike nwere ike ime ka akpa ahụ gbajie. The flash point bụ 39 ℃, mgbawa ịgba bụ 4.0% ~ 16.0%, na kacha ekwe ịta n'ikuku adịghị gafere 25mg/m3. Acid dị ọcha ga-adaba n'ime kristal dị ka ice n'okpuru ebe mgbaze, yabụ acetic acid a na-akpọkwa glacial acetic acid.
Enwere ike ịhụ na abụọ ahụ abụghị otu, ebe ọkụ ọkụ nke ice acetic acid bụ 39 ℃, njedebe mgbawa bụ 4.0% ~ 16.0%, na njedebe kachasị ike na ikuku adịghị agafe 25mg / m3, nke bụ na ngwongwo ndị dị ize ndụ, na acetic acid abụghị ihe dị ize ndụ.
