Na farko, yanayin ya bambanta
1, ice acetic acid: shi ne anhydrous acetic acid, acetic acid daya ne daga cikin muhimman kwayoyin acid, kwayoyin mahadi.
2, acetic acid: shi ne Organic monic acid, babban bangaren vinegar.
Na biyu, halaye daban-daban
1, glacial acetic acid: yana ƙarfafawa cikin ƙanƙara a ƙananan zafin jiki, wanda aka fi sani 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.
2, acetic acid: ya ƙunshi 98% glacial acetic acid, dangi yawa (ruwa ne 1): 1.050; Danko (mPa.s): 1.22 (20 ℃); Ruwan tururi a 20 ℃ (KPa): 1.5; Bayyanawa da wari: Ruwa mara launi tare da ƙamshin acetic acid.
Uku, amfani daban-daban
1, glacial acetic acid: yafi amfani da kira na vinyl acetate, acetate fiber, acetic anhydride, acetate, karfe acetate da halogenated acetic acid. Hakanan yana da mahimmancin albarkatun ƙasa don magunguna, rini, magungunan kashe qwari da sauran ƙwayoyin halitta.
2, acetic acid: za a iya amfani da matsayin acidity regulator, acidifier, pickling wakili, flavoring wakili, kayan yaji, da dai sauransu.
