coagulant

Kev tsim kho

Tiv thaiv pob zeb los ntawm khov. Tsis tas li ntawd, nws yog dav siv nyob rau hauv kev kho dej, hluavtaws fibers, tshuaj tua kab, yas, tawv, xim, hlau ua thiab roj hmab industriesAcetic acid (tseem hu ua acetic acid los yog glacial acetic acid) ₃ yog ib qho organic monic acid vim cov qaub thiab pungent. tsw hauv vinegar. Ntshiab anhydrous acetic acid (glacial acetic acid) yog cov kua tsis muaj xim hygroscopic nrog qhov chaw khov ntawm 16.7 ° C (62 ° F). Thaum solidification, nws dhau los ua cov xim tsis muaj xim. Txawm hais tias acetic acid yog cov kua qaub tsis muaj zog raws li nws lub peev xwm los cuam tshuam rau hauv cov tshuaj aqueous, acetic acid yog corrosive thiab nws cov vapors ua rau khaus qhov muag thiab qhov ntswg.

Acetic acid nyob rau hauv chav tsev kub yog cov kua tsis muaj xim uas muaj zog pungent acid saj. Lub melting point ntawm acetic acid yog 16.6 ℃ (289.6 K). Kub taw tes 117.9 ℃ (391.2 K). Tus txheeb ze ntom ntom yog 1.05, lub teeb nyem yog 39 ℃, thiab qhov tawg txwv yog 4% ~ 17% (ntim). Ntshiab acetic acid yuav khov rau hauv cov dej khov nab kuab hauv qab lub melting point, yog li anhydrous acetic acid kuj hu ua glacial acetic acid. Acetic acid yog soluble nyob rau hauv dej thiab ethanol, thiab nws cov kua aqueous yog weakly acidic. Acetate kuj yooj yim soluble hauv dej, thiab cov kua dej aqueous yog qhov yooj yim.
