Ntshiab anhydrous acetic acid (glacial acetic acid) yog cov kua tsis muaj xim hygroscopic nrog qhov chaw khov ntawm 16.6 degree (62 ℉). Nws yog ib qho tsis muaj xim crystal tom qab solidification. Nws cov tshuaj aqueous yog weakly acidic thiab corrosive heev. Nws yog corrosive heev rau hlau. Nws vapor yog irritating rau lub qhov muag thiab qhov ntswg.

Acetic acid yog dav faib nyob rau hauv cov xwm, piv txwv li, nyob rau hauv txiv hmab txiv ntoo los yog zaub roj, acetic acid feem ntau muaj nyob rau hauv daim ntawv ntawm esters. Acetic acid muaj nyob rau hauv daim ntawv ntawm dawb acid nyob rau hauv cov tsiaj cov ntaub so ntswg, excreta thiab ntshav. Ntau cov kab mob tuaj yeem hloov cov organic sib txawv rau hauv acetic acid los ntawm fermentation.

1. Kev lag luam siv

1.1 Acetic acid yog cov khoom lag luam tseem ceeb thiab ib qho tseem ceeb ntawm cov organic acids. Feem ntau yog siv hauv kev tsim cov acetic anhydride, acetate thiab cellulose acetate, thiab lwm yam. Polyvinyl acetate tuaj yeem ua rau hauv cov yeeb yaj kiab thiab cov nplaum, thiab tseem yog cov khoom siv raw ntawm hluavtaws fiber ntau vinylon. Cellulose acetate yog siv los ua rayon thiab motion duab zaj duab xis.

1.2 Acetates tsim los ntawm qis cawv yog cov kuab tshuaj zoo heev thiab tau siv dav hauv kev lag luam xim. Vim tias acetic acid dissolves feem ntau cov organics, nws kuj yog cov organic hnyav (xws li, rau oxidation ntawm p-xylene rau terephthalic acid).

1.3 Acetic acid tuaj yeem siv rau hauv qee qhov kev xaiv thiab polishing kev daws teeb meem, raws li qhov tsis muaj nyob hauv cov kua qaub tsis muaj zog (xws li zinc plating thiab electroless npib tsib xee plating), ua ib qho ntxiv hauv ib nrab ci npib tsib xee plating electrolyte, thiab ua tus neeg sawv cev hauv zinc thiab cadmium passivation cov kev daws teeb meem los txhim kho cov kev sib khi quab yuam ntawm cov zaj duab xis passivation, thiab feem ntau yog siv los kho cov pH ntawm qaug zog acid plating daws.

1.4 Nws yog siv rau hauv kev tsim cov acetate, xws li manganese, sodium, lead, txhuas, zinc, cobalt thiab lwm yam hlau ntsev, uas yog dav siv los ua catalysts, auxiliaries hauv textile dyeing thiab tawv tanning industries; lead acetate yog xim xim ntawm cov hlau lead dawb; lead tetraacetate yog cov organic hluavtaws reagent (piv txwv li, lead tetraacetate tuaj yeem siv los ua cov oxidant muaj zog, muab cov acetoxy thiab npaj cov organic lead compounds).

1.5 Acetic acid kuj yog siv los ua cov tshuaj analytical reagent, organic synthesis, thiab nyob rau hauv synthesis ntawm pigments thiab tshuaj.

2. Kev siv zaub mov

Hauv kev lag luam khoom noj khoom haus, acetic acid yog siv los ua cov kua qaub, cov tshuaj tsw qab thiab cov txuj lom, thiab thaum cov khoom siv hluavtaws tsim, cov acetic acid yog diluted rau {{0}} feem pua ​​ntawm dej, thiab ntau yam flavoring. cov neeg sawv cev tau ntxiv, kom qhov tsw zoo ib yam li cov cawv cawv, lub sijhawm tsim khoom yog luv, thiab tus nqi qis. Nws tuaj yeem siv los ua tus neeg sawv cev souring, compound seasoning, vinegar, kaus poom zaub mov, jelly thiab cheese. Nws tuaj yeem siv raws li qhov xav tau ntau lawm. Nws kuj tuaj yeem siv los ua tus neeg sawv cev rau koji-flavor cawv ntawm qhov ntau npaum li cas ntawm 0.1 txog 0.3 G / kg.
