Ntshiabglacial acetic acid, uas yog, anhydrous acetic acid, acetic acid yog ib qho tseem ceeb ntawm cov organic acids, organic compounds. Nws solidifies rau hauv dej khov ntawm qhov kub thiab txias thiab feem ntau hu uaglacial acetic acid. Lub freezing point yog 16.6° C (62° F), thiab tom qab solidification, nws dhau los ua cov xim tsis muaj xim. Nws cov tshuaj aqueous yog tsis muaj zog acidic thiab corrosive heev, thiab nws muaj zog corrosive rau hlau. Cov pa muaj qhov ua rau khaus ntawm qhov muag thiab qhov ntswg. Yog li, dab tsi yog cov kev siv tshwj xeeb ntawm glacial acetic acidhauv kev lag luam sib txawv?
Ua ntej, glacial acetic acid industrial siv
1. Siv rau hluavtaws dyes thiab inks.
2. Hauv kev lag luam khoom noj khoom haus, nws yog siv los ua acidity regulator, acidifier, pickling agent, tsw enhancer, txuj lom thiab lwm yam. Nws kuj yog ib tug zoo antimicrobial neeg sawv cev, feem ntau yog vim nws lub peev xwm los txo cov pH hauv qab pH xav tau rau kev pom microbial loj hlob.
3. Nws yog siv rau hauv kev lag luam roj hmab thiab yas. Nws yog siv los ua cov kuab tshuaj thiab cov khoom pib rau ntau yam tseem ceeb polymers (xws li PVA, PET, thiab lwm yam) hauv kev lag luam roj hmab thiab yas.
4. Siv los ua cov khoom pib rau xim thiab cov khoom siv nplaum.
5. Glacial acetic acid Kuj tseem ua lub luag haujlwm tseem ceeb hauv kev ntxhua khaub ncaws, feem ntau yog tiv thaiv kev poob ntawm cov xim ntawm cov khaub ncaws, muaj zog tshem tawm cov stains, thiab tuaj yeem cuam tshuam pH, yog liglacial acetic acid yog nrov nyob rau hauv khaub ncaws. Thaum siv, nws yuav tsum tau siv raws li qee cov lus qhia, thiab tsis tuaj yeem siv qhov muag tsis pomglacial acetic acid.
Thib ob,glacial acetic acid kev siv tshuaj
1. Rau cov synthesis ntawm cellulose acetate. Cellulose acetate yog siv hauv cov duab thaij duab thiab textiles. Ua ntej kev tsim cov yeeb yaj kiab cellulose acetate, cov duab thaij duab tau siv los ntawm nitrates thiab muaj ntau yam kev txhawj xeeb txog kev nyab xeeb.
2. Siv los ua cov kuab tshuaj rau cov synthesis ntawm terephthalic acid. P-xylene yog oxidized rau terephthalic acid. Terephthalic acid yog siv nyob rau hauv cov synthesis ntawm PET thiab yog dav siv nyob rau hauv kev tsim cov yas hwj.
3. Dav siv los tsim cov esters los ntawm kev ua haujlwm nrog ntau yam cawv. Acetate derivatives yog dav siv los ua zaub mov additives.
4. Siv rau kev sib txuas ntawm vinyl acetate monomer. Cov monomer tuaj yeem ua polymerized los ua poly (vinyl acetate), uas feem ntau hu ua PVA.
5. Siv raws li hnyav nyob rau hauv ntau cov organic catalytic tshua.
6. Siv raws li nplai thiab xeb tshem tawm. Thaum twgacetic acidreacts nrog dej, cov nplai hisses thiab npuas ploj, rhuav tshem nws los ntawm cov khoom mus rau hauv cov kua uas tau yooj yim tshem tawm.
