Cas Cas Cas Cas Tus Naj Npawb: 64 - 19 - 7

● Pom: Ntawm chav tsev kub, nws yog cov kua tsis muaj kob nrog lub pungent tsw. Thaum qhov ntsuas kub qis dua nws lub ntsiab lus melting ntawm 16.6 degree, nws solidifies rau hauv lub xim tsis muaj xim, uas yog vim li cas nws hu ua "glacial" acetic acid.

● Cov Kev Lag Luam Chem: Nws yog ib qho tseem ceeb rau cov khoom siv tshuaj raw ua ke, siv hauv kev tsim cov tshuaj ntau yam xws li acetic anhydride, yas acetate, thiab cellulose acetate. Cov tshuaj no tau siv dav hauv kev tsim cov plastics, cov puv, txheej, thiab cov nplaum.

● ● Kev lag luam khoom noj khoom haus: Nws yog siv los ua cov kev tswj hwm acidality thiab txuag hluav taws xob kev lag luam khoom noj. Nyob rau hauv pickles, cov kua ntses, thiab lwm yam khoom noj, nws tuaj yeem kho qhov kev loj hlob ntawm cov microorganisms kom ntev lub txee lub neej ntawm cov zaub mov.

Hlau Kuaj: Nws yog feem ntau siv raws li cov kuab tshuaj thiab reagent nyob rau hauv lub chaw soj nstuam. Piv txwv li, nws yog siv rau hauv cov khoom siv hluav taws xob hauv nruab nrog cev thiab ua cov kuab tshuaj rau qee cov ntsev inorganic.
