Acetic acid, wanda kuma aka sani da acetic acid (36% -38%), glacial acetic acid (98%), dabarar sinadarai CH3COOH, wani kwayoyin monic acid ne, babban bangaren vinegar. Pure anhydrous acetic acid (glacial acetic acid) wani nau'in hygroscopic ne mara launi tare da daskarewa na 16.6 ° C (62 ° F) kuma ya zama crystal mara launi bayan ƙarfafawa. Maganin sa na ruwa yana da rauni acidic kuma yana lalata, kuma tururi yana fushi ga idanu da hanci.
Glacial acetic acid (tsaftataccen al'amari), watau anhydrous acetic acid, kwayoyin fili. Yana ƙarfafa cikin ƙanƙara a ƙananan yanayin zafi kuma ana kiransa da glacial acetic acid. Fadada ƙarar yayin ƙarfafawa na iya haifar da ɓarkewar akwati. Ma'anar walƙiya shine 39 ℃, iyakar fashewa shine 4.0% ~ 16.0%, kuma matsakaicin da aka yarda da shi a cikin iska bai wuce 25mg/m3 ba. Pure acetic acid zai daskare zuwa cikin lu'ulu'u-kamar kankara a ƙasa da wurin narkewa, don haka anhydrous acetic acid kuma ana kiransa glacial acetic acid.
Ana iya ganin cewa su biyun ba iri ɗaya ba ne, ma'aunin walƙiya na ice acetic acid shine 39 ℃, iyakar fashewar shine 4.0% ~ 16.0%, kuma matsakaicin da aka yarda da shi a cikin iska bai wuce 25mg/m3 ba, wanda nasa ne. zuwa kayayyaki masu haɗari, kuma acetic acid ba kayan haɗari ba ne.
