• Glacial acetic acidmuaj cov ntsiab lus dej tsawg heev, uas pab txhim kho cov tshuaj tiv thaiv kev ua haujlwm thiab txo qhov tsis xav tau los ntawm -cov khoom lag luam thaum lub sij hawm tshuaj synthesis.
• Piv nrog rau diluted acetic acid, nws muaj ntau dua reactivity, tso cai rau cov neeg tsim khoom siv cov khoom me me thaum ua tiav cov tshuaj tiv thaiv zoo.
• Nws cov purity siab ua kom muaj kev tswj xyuas zoo dua hauv cov txheej txheem kev lag luam xws li esterification thiab polymerization, ua rau cov khoom ruaj khov dua.
• Txij li thaum nws twb muaj concentrated, ntxiv ua ntej - cov kauj ruam tseem ceeb yog feem ntau tsis tsim nyog, pab txo cov sij hawm ua, kev siv hluav taws xob, thiab cov nqi tsim khoom.
• Cov qib impurity qis kuj txo qis cov kev ua kom huv hauv qab, txhim kho tag nrho cov khoom lag luam thiab cov khoom sib xws.

Kev siv Glacial Acetic Acid

Muaj kev siv ntawm Glacial Acetic Acid hauv kev tsim khoom

Hauv kev tsim tshuaj, glacial acetic acid yog ib qho tseem ceeb nruab nrab siv los ua ke acetic anhydride, vinyl acetate, thiab cellulose acetate, uas yog siv dav hauv plastics, adhesives, coatings, thiab hluavtaws fibers. Ntiaj teb no noj acetic acid ntau tshaj 16 lab tons ib xyoos ib zaug, nrog ib tug tseem ceeb sib koom siv nyob rau hauv vinyl acetate monomer (VAM) ntau lawm. Piv nrog rau diluted acetic daws, glacial acetic acid muab cov tshuaj tiv thaiv ntau dua thiab ruaj khov yield tswj hauv kev lag luam synthesis.

glacial acetic acid siv hauv cov khoom noj

Hauv cov khoom noj khoom haus, glacial acetic acid yog diluted rau hauv vinegar tov siv rau flavoring thiab preservation, pab inhibit cov kab mob loj hlob thiab ntev txee lub neej. Cov kua txiv hmab txiv ntoo tsuas muaj 4-8% acetic acid, thaum glacial acetic acid muab ze li ntawm 100% concentration ua ntej dilution, tso cai rau kev tswj xyuas cov txheej txheem hauv kev ua zaub mov. Nws cov khoom siv tshuaj tua kab mob ua rau nws siv dav hauv pickling zaub, kua ntses, thiab condiments, qhov twg nws txo qis tus nqi spoilage thaum khaws cia thiab tsheb thauj mus los.

glacial acetic acid siv nyob rau hauv textile

Hauv kev tsim textile, glacial acetic acid yog siv rau hauv dye fixation thiab pH kev cai thaum lub sij hawm ua ntaub, txhim kho xim stability thiab ntxuav tsis kam. Kev lag luam textile dyeing tuaj yeem siv ntau txhiab tons ib xyoos ib zaug hauv cov chaw tsim khoom loj xws li Tuam Tshoj thiab Bangladesh. Muab piv nrog cov txheej txheem dyeing tsis kho, cov ntaub ua tiav nrog cov tshuaj acetic acid tswj tau pom cov xim zoo dua qub thiab txo qis fading tus nqi, ua rau nws tseem ceeb rau siab - zoo textile xov.

glacial acetic acid siv tshuaj

Hauv kev lag luam tshuaj, glacial acetic acid yog siv los ua cov tshuaj reagent hauv kev sib xyaw ntawm cov khoom xyaw tshuaj nquag, suav nrog tshuaj aspirin thiab tshuaj tua kab mob nruab nrab. Pharmaceutical-qib ntu txuas ntxiv nce ntxiv nrog rau kev xav tau kev noj qab haus huv thoob ntiaj teb, tshwj xeeb hauv Asia uas muaj peev xwm tsim tshuaj tau nthuav dav sai hauv kaum xyoo dhau los. Txawm li cas los xij, vim nws qhov xwm txheej corrosive, nws yuav tsum muaj cov qauv tswj nruj, suav nrog corrosion-cov khoom siv tiv thaiv thiab tswj qhov cua kom ntseeg tau tias cov neeg ua haujlwm muaj kev nyab xeeb thiab cov khoom ruaj khov.
