Chaw Tsim Khoom Zoo Nqe Glacial Acetic Acid CAS: 64-19-7

piav qhia luv luv:

Acetic acid yog ib yam kua tsis muaj xim los yog siv lead ua nrog ib qho tsw qab zoo li kua txiv qaub thiab yog ib qho ntawm cov carboxylic acids yooj yim tshaj plaws thiab yog ib qho tshuaj reagent siv dav. Acetic acid muaj kev siv dav dav ua ib qho reagent hauv chav kuaj, hauv kev tsim cov cellulose acetate feem ntau rau cov yeeb yaj kiab duab thiab polyvinyl acetate rau cov kua nplaum ntoo, cov fibers hluavtaws, thiab cov ntaub ntawv ntaub. Acetic acid kuj tau siv dav ua tus neeg sawv cev descaling thiab acidity regulator hauv kev lag luam zaub mov.

Cov ntawv thov ntawm Glacial Acetic Acid

1. Acetic acid muaj nyob rau hauv vinegar. Nws yog tsim nyob rau hauv lub distillation ntawm ntoo. Nws pom ntau daim ntawv thov nyob rau hauv kev lag luam tshuaj. Nws yog siv nyob rau hauv kev tsim cov cellulose acetate, acetate rayon, thiab ntau yam acetate thiab acetyl compounds; ua ib tug solvent rau gums, roj, thiab resins; ua ib tug zaub mov preservative nyob rau hauv printing thiab dyeing; thiab nyob rau hauv organic synthesis.
2. Acetic acid yog ib yam tshuaj lom neeg tseem ceeb hauv kev lag luam. Qhov tshuaj tiv thaiv ntawm acetic acid nrog cov tshuaj hydroxyl, tshwj xeeb tshaj yog cawv, ua rau muaj cov acetate esters. Kev siv acetic acid ntau tshaj plaws yog nyob rau hauv kev tsim cov vinyl acetate. Vinyl acetate tuaj yeem tsim los ntawm kev tshuaj tiv thaiv ntawm acetylene thiab acetic acid. Nws kuj tseem tsim los ntawm ethylene thiab acetic acid. Vinyl acetate yog polymerized rau hauv polyvinyl acetate (PVA), uas yog siv rau hauv kev tsim cov fibers, zaj duab xis, nplaum, thiab xim latex.
Cellulose acetate, uas siv rau hauv cov ntaub thiab cov yeeb yaj kiab thaij duab, yog tsim los ntawm kev sib xyaw cellulose nrog acetic acid thiab acetic anhydride nyob rau hauv qhov muaj sulfuric acid. Lwm cov esters ntawm acetic acid, xws li ethyl acetate thiab propyl acetate, yog siv rau ntau yam kev siv.
Acetic acid yog siv los tsim cov yas polyethylene terephthalate (PET). Acetic acid yog siv los tsim cov tshuaj.
3. Glacial Acetic Acid yog ib yam khoom uas ua rau cov kua qaub tsis muaj xim, uas muaj saj qaub thaum muab dej rau hauv. Nws muaj qhov huv 99.5% lossis siab dua thiab ua rau cov kua qaub crystallizes ntawm 17°c. Nws yog siv rau hauv cov kua zaub xas lav hauv daim ntawv diluted kom muab cov kua qaub acetic uas xav tau. Nws yog siv ua ib yam khoom khaws cia, tshuaj ua kom cov kua qaub, thiab tshuaj ua kom saj. Nws kuj tseem hu ua acetic acid, glacial.
4. Acetic acid yog siv ua cov kua txiv hmab txiv ntoo hauv rooj, ua cov tshuaj tiv thaiv thiab ua cov khoom nruab nrab hauv kev lag luam tshuaj lom neeg, piv txwv li acetate fibers, acetates, acetonitrile, tshuaj, tshuaj tsw qab, cov neeg ua kom mos, cov xim zas (indigo) thiab lwm yam. Cov Ntaub Ntawv Khoom.
5. Nws yog siv rau hauv cov kua qaub thiab cov kua qaub uas tsis yog kua qaub.
6. Tsim ntau yam acetates, acetyl compounds, cellulose acetate, acetate rayon, plastics thiab roj hmab hauv tanning; ua ntxhua khaub ncaws qaub; luam ntawv calico thiab dyeing silk; ua acidulant thiab preservative hauv cov khoom noj; solvent rau cov pos hniav, resins, volatile roj thiab ntau lwm yam tshuaj. Siv dav hauv kev lag luam organic syntheses. Pharmaceutical pab (acidifier).
