Cov Txheej Txheem Ntau Lawm ntawm Glacial Acetic Acid

Cov txheej txheem tsim cov glacial acetic acid tuaj yeem muab faib ua cov kauj ruam hauv qab no:

Kev Npaj Khoom Siv Raw: Cov khoom siv tseem ceeb rau glacial acetic acid yog ethanol thiab tus neeg sawv cev oxidizing. Ethanol feem ntau tau los ntawm kev fermentation lossis kev tsim tshuaj lom neeg, thaum tus neeg sawv cev oxidizing feem ntau yog oxygen lossis hydrogen peroxide.

Kev Ua Pa Tawm: Ethanol thiab cov neeg sawv cev oxidizing raug pub rau hauv lub thawv tshuaj tiv thaiv, qhov twg qhov kev ua pa tawm raug ua tiav hauv qab qhov kub thiab siab tswj tau. Feem ntau qhov kev ua pa tawm tshwm sim nyob rau hauv qhov muaj cov tshuaj catalyst acidic, uas ua ntej oxidizes ethanol rau acetaldehyde thiab tom qab ntawd oxidizes nws mus rau acetic acid.

Kev Hloov Pauv Acetic Acid: Acetaldehyde raug hloov pauv mus ua acetic acid. Ib qho tseem ceeb catalyst hauv kauj ruam no yog cov kab mob acetic acid. Los ntawm kev sib cuag nrog cov kab mob no, acetaldehyde raug oxidized mus ua acetic acid, thaum carbon dioxide thiab dej kuj tsim tawm ua cov khoom seem.

Kev Ntxuav Acetic Acid: Cov acetic acid sib tov uas tau los ntawm kev ntxuav ntxiv. Cov txheej txheem ntxuav suav nrog kev distillation thiab crystallization. Distillation suav nrog kev sib cais acetic acid ntawm cov sib tov los ntawm kev tswj qhov kub thiab siab, ua rau muaj acetic acid purity siab dua. Txoj kev crystallization, ntawm qhov tod tes, suav nrog kev ntxiv cov kuab tshuaj tshwj xeeb los ua rau acetic acid crystallize rau hauv cov acetic acid crystals ntshiab.

Ntim thiab Khaws Cia: Cov kua qaub acetic uas tau lim lawm raug ntim, feem ntau yog ntim rau hauv cov thawv yas lossis cov fwj iav. Cov kua qaub acetic uas tau ntim lawm ces raug khaws cia rau hauv qhov chaw txias thiab qhuav.

Los ntawm cov kauj ruam no, cov kua qaub glacial acetic acid tuaj yeem tsim tau. Nws yog ib qho tseem ceeb kom tswj tau qhov kub thiab txias ntawm cov tshuaj tiv thaiv, qhov siab, thiab qhov concentration ntawm ntau yam catalysts thoob plaws hauv cov txheej txheem tsim khoom kom ntseeg tau tias kev ua tiav ntawm cov tshuaj tiv thaiv zoo thiab cov khoom zoo ruaj khov.
