Acetic acid

piav qhia luv luv:

Nws yog ib qho organic monic acid, lub ntsiab tivthaiv ntawm vinegar.Ntshiab anhydrous acetic acid (glacial acetic acid) yog cov kua tsis muaj xim hygroscopic, nws cov kua aqueous yog tsis muaj zog acidic thiab corrosive, thiab nws muaj zog corrosive rau hlau.

Cov qauv siv lead ua ntawm acetic acid qhia tau hais tias cov molecules raug khi rau hauv dimers (tseem hu ua dimers) los ntawm hydrogen bonds, thiab cov dimers kuj muaj nyob hauv lub xeev vapor ntawm 120 ° C. Dimers muaj kev ruaj ntseg siab, thiab nws tau raug pov thawj tias carboxylic. Cov kua qaub uas tsis tshua muaj qhov hnyav xws li formic acid thiab acetic acid muaj nyob rau hauv daim ntawv ntawm dimers hauv cov khoom, kua lossis txawm tias lub xeev gaseous los ntawm txoj kev txiav txim siab molecular hnyav los ntawm kev txo qis qis thiab X-ray diffraction.Thaum acetic acid yaj nrog dej, hydrogen bonds ntawm cov dimers tawg sai sai.Lwm cov carboxylic acids qhia zoo li dimerization.

Khoom siv

Kev siv tshuab

1. acetic acid yog cov khoom siv tshuaj lom neeg ntau, yog ib qho tseem ceeb ntawm cov organic acids.Nws yog tsuas yog siv rau zus tau tej cov acetic anhydride, acetate thiab cellulose acetate.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.

2. acetic ester tsim los ntawm cov cawv tsawg yog cov kuab tshuaj zoo heev, dav siv hauv kev lag luam xim.Vim tias acetic acid dissolves feem ntau cov organic teeb meem, nws kuj yog siv los ua cov organic hnyav (xws li oxidation ntawm p-xylene los tsim terephthalic acid).

3. acetic acid yuav siv tau nyob rau hauv ib co pickling thiab polishing kev daws teeb meem, nyob rau hauv ib tug weakly acidic tov raws li ib tug tsis muaj (xws li galvanized, electroless npib tsib xee plating), nyob rau hauv lub semi-ci nickel plating electrolyte raws li ib tug additive, nyob rau hauv lub passivation tov ntawm zinc. , cadmium tuaj yeem txhim kho lub zog sib txuas ntawm cov yeeb yaj kiab passivation, thiab feem ntau siv los kho cov pH ntawm cov dej tsis muaj zog acidic.

4. rau zus tau tej cov acetate, xws li manganese, sodium, lead, txhuas, zinc, cobalt thiab lwm yam hlau ntsev, lug siv raws li catalysts, ntaub dyeing thiab tawv tanning kev lag luam additives;Lead acetate yog xim xim hlau lead dawb;Lead tetraacetate yog ib qho organic synthesis reagent (piv txwv li, lead tetraacetate tuaj yeem siv los ua tus neeg sawv cev oxidizing muaj zog, muab cov acetoxy thiab npaj cov organic lead compounds, thiab lwm yam).

5. acetic acid kuj tseem siv tau los ua cov tshuaj analytical reagent, organic synthesis, pigment thiab tshuaj synthesis.

Kev siv zaub mov

Hauv kev lag luam khoom noj khoom haus, acetic acid yog siv los ua cov kua qaub, tshuaj tsw qab thiab tshuaj tsw qab thaum ua hluavtaws vinegar, acetic acid yog diluted rau 4-5% nrog dej, thiab ntau yam tshuaj tsw qab ntxiv.Cov tsw zoo ib yam li cawv txiv hmab, thiab lub sijhawm tsim khoom yog luv luv thiab tus nqi pheej yig.Raws li tus neeg sawv cev qaub, tuaj yeem siv rau kev sib xyaw ua ke, kev npaj ntawm vinegar, cov kaus poom, jelly thiab cheese, raws li kev xav tau ntawm kev siv tsim nyog.Nws tseem tuaj yeem tsim cov aroma enhancer ntawm xyab cawv, tus nqi ntawm kev siv yog 0.1 ~ 0.3 g / kg.
