Ni akọkọ, iseda yatọ
1, ice acetic acid: jẹ acetic acid anhydrous, acetic acid jẹ ọkan ninu awọn pataki Organic acids, Organic compounds.
2, acetic acid: jẹ ẹya Organic monic acid, akọkọ paati kikan.
Keji, o yatọ si abuda
1, glacial acetic acid: o ṣinṣin sinu yinyin ni iwọn otutu kekere, ti a mọ ni glacial acetic acid. Imugboroosi iwọn didun lakoko imuduro le fa ki eiyan naa rupture. Ojuami filasi jẹ 39 ℃, opin bugbamu jẹ 4.0% ~ 16.0%, ati ifọkansi ti o pọju laaye ninu afẹfẹ ko kọja 25mg/m3. Acid acetic funfun yoo di didi sinu awọn kirisita ti o dabi yinyin ni isalẹ aaye yo, nitorinaa acetic acid anhydrous tun pe ni glacial acetic acid.
