Acetic acid (CAS 64-}19-7) yog cov kua tsis muaj xim tsis muaj kob nrog lub zog, txawv qaub saj thiab tsw ntxhiab tsw. Feem ntau lub npe hu ua cov khoom tseem ceeb ntawm cov kua qaub hauv tsev, acetic acid plays lub luag haujlwm ntau dua li chav ua noj - nws yog ib qho tseem ceeb tshaj plaws organic acids hauv kev lag luam niaj hnub no.
Tshuaj thiab Industrial Manufacturing
High -purity acetic acid (99.85%)yog ib qho tseem ceeb raw khoom rau kev tsim ntau yam tshuaj, xws li ethyl acetate, chloroacetic acid, vinyl acetate, acetic anhydride, cellulose acetate, thiab lwm yam.
Polyvinyl acetate yog siv rau hauv cov yeeb yaj kiab thiab cov nplaum, nrog rau cov khoom siv raw rau hluavtaws fibers.
Cellulose acetate yog dav siv nyob rau hauv zus tau tej cov rayon thiab yees duab zaj duab xis.
Tsawg cawv acetates, tsim los ntawm acetic acid, ua cov kuab tshuaj zoo heev hauv kev lag luam xim thiab txheej txheej.
Kev lag luam kws tshuaj
Hauv cov tshuaj, acetic acid ua cov kuab tshuaj, stabilizer, thiab flavoring tus neeg sawv cev hauv cov tshuaj formulations. Nws yog dav siv nyob rau hauv zus tau tej cov tshuaj tua kab mob, analgesics, thiab anticancer tshuaj, ua rau nws indispensable rau niaj hnub tshuaj manufacturing.
Daim Ntawv Thov Kev Lag Luam Khoom Noj
Acetic acid kuj tau pom zoo siv los ua cov kua qaub thiab cov tshuaj tsw qab hauv cov khoom noj xws li vinegar, pickles, condiments, jellies, cov kaus poom, thiab cheese. Thaum siv kom zoo, nws txhim kho tsw ruaj khov thiab txuas ntxiv txee lub neej.
Laboratory thiab analytical siv
Hauv cov chaw soj nstuam, glacial acetic acid yog siv los ua cov tshuaj analytical reagent, chromatography hnyav, thiab nruab nrab rau tsis yog -aqueous titration. Vim nws zoo heev polar protic hnyav zog, nws kuj yog siv rau recrystallization purify organic tebchaw thiab rau kev kwv yees ntawm weakly alkaline tshuaj xws li amides.
Kev tsim cov Acetate ntsev thiab Catalysts
Acetic acid yog dav siv los ua ke ntau yam ntawm cov organic thiab inorganic acetates, txhua qhov ua haujlwm tseem ceeb hauv kev lag luam:
- Sodium acetate - siv hauv textiles thiab ua zaub mov preservative (E262)
- Tooj liab (II) acetate - pigment thiab fungicide
- Silver acetate - tshuaj tua kab
- Palladium (II) acetate - catalyst rau organic coupling tshua zoo li cov tshuaj tiv thaiv Heck
- Aluminium thiab Hlau (II) acetates - mordants rau dyeing txheej txheem
