Cov qauv siv lead ua ntawm cov molecules tau ua tiav rau hauv lub xeev Dimers, thiab nws tau ua tiav cov kua qaub nyob rau hauv daim ntawv ntawm cov tawv nqaij muaj zog, kua lossis txawm tias lub xeev muaj zog los ntawm txoj kev molecular hnyav kev txiav txim siab los ntawm khov taw tes txo thiab X-ray diffraction. Thaum acetic acid yog yaj nrog dej, cov hydrogen khi ntawm cov dimers tawg sai sai. Lwm cov roj carboxylic acids qhia zoo ib yam li yav tas los.

Kev Siv Siv
1. Acetic Acid yog ib qho khoom lag luam tshuaj, yog ib qho tseem ceeb tshaj tawm cov organic. Nws yog tsuas yog siv rau kev tsim cov acetic anhydride, acetate thiab cellulose acetate. Polyvinyl acetate tuaj yeem ua rau hauv cov yeeb yaj kiab thiab cov nplaum, thiab tseem cov khoom siv raw ntawm hluavtaws fiber ntau. Cellulose acetate yog siv los ua Rayon thiab cov duab kos duab zaj duab xis.
2. Lub aceticter tsim los ntawm kev haus dej ntau yog cov kuab tshuaj zoo, dav siv hauv kev lag luam pleev xim. Vim tias acetic acid dissolves feem ntau cov organic teeb meem, nws kuj yog siv los ua ib qho organic huab cua (piv txwv li rau oxidation ntawm P-Xylene los tsim cov acid med).
3. Acetic Acid tuaj yeem siv rau qee cov kev ua kom zoo nkauj, hauv lub pob zeb uas tsis muaj zog, thiab siv cov nplais uas muaj zog ntawm cov pencanized, thiab siv tau los kho cov pheeb suab.
4. Rau kev tsim cov acetate, sodium, txhuas, txhuas, tuab siv ua catalysts, ntaub nplawm thiab tawv tanning kev lag luam ntxiv; Lead Acetate yog xim xim txhuas dawb; Lead Tetraacetate yog ib qho khoom siv hluav taws xob organic (piv txwv li, muab ib qho chaw ntawm acetoxy thiab npaj cov organic txhuas compound, thiab lwm yam).
5. Acetic acid kuj tseem siv tau ua ib qho kev ntsuas tshuaj tiv thaiv kab mob organic, xim thiab yeeb tshuaj synthesis.
Siv
Hauv kev lag luam khoom noj khoom haus, acetic acid yog siv los ua ib qho kua qaub thiab cov tshuaj acatics thaum ua cov dej ua pa, thiab cov khoom noj tsw qab yog ntxiv. Qhov qab yog ib yam li ntawm cov cawv vinegar, thiab lub sijhawm tsim khoom yog luv thiab tus nqi yog pheej yig. Raws li tus sawv cev tus neeg sawv cev, tuaj yeem siv rau cov khoom siv vinegar, cov kaus poom, cov kaus poom, jelly thiab cheese, raws li kev tsim khoom xav tau ntawm kev siv tsim nyog. Nws tseem tuaj yeem sau lub aroma txhim kho caw, tus nqi ntawm kev siv yog 0.1 ~ 0.3 g / kg.
