Raws li cov kuab tshuaj ntsuab, methyl acetate raug zam los ntawm kev txwv thiab siv los ua cov kuab tshuaj organic hauv kev tsim ester, txheej, number case, xim, adhesives thiab tawv;thiab ua raws li tus neeg sawv cev foaming rau polyurethane ua npuas ncauj, ntxiv rau, nws tseem tuaj yeem siv los ua cov khoom siv roj thiab roj hauv kev tsim cov tawv nqaij, tshuaj tsw qab, thiab lwm yam. yog 210kt.
Kawm paub ntau ntxiv txog Methyl Acetate
Methyl Acetate yog dab tsi?
Ntawm qhov kub thiab txias, methyl acetate yog 25% soluble hauv dej.Nws muaj ntau dua solubility hauv dej ntawm qhov kub thiab txias.Nyob rau hauv lub xub ntiag ntawm muaj zog aqueous bases los yog acids, methyl acetate tsis ruaj khov.Nrog lub flashpoint ntawm -10 ° C thiab tus nqi flammability ntawm 3, nws yog heev flammable.Methyl acetate yog cov kuab tshuaj lom neeg tsawg feem ntau pom muaj nyob hauv cov kua nplaum thiab cov ntsia thawv polish tshem tawm.Kua txiv, txiv hmab txiv ntoo, thiab txiv tsawb yog cov txiv hmab txiv ntoo uas muaj methyl acetate.
Kev Siv Hluav Taws Xob
Cov tshuaj tiv thaiv ntawm carbonylation nrog methyl acetate los tsim acetic anhydride yog siv hauv kev lag luam.Nws kuj tseem siv los ua cov kuab tshuaj hauv cov xim, kua nplaum, ntsia thawv polish, thiab graffiti tshem tawm, nrog rau cov roj nplua nyeem, cov khoom nruab nrab, thiab cov khoom siv ua haujlwm.
Methyl acetate kuj tseem siv los ua cov tshuaj nruab nrab hauv kev tsim cov cellulose adhesives thiab perfumes, nrog rau kev sib xyaw ntawm chlorophacinone, diphacinone, fenfluramine, o-methoxy phenylacetone, p-methoxy phenylacetone, methyl cinnamate, methyl cyldacetate, .
Methyl acetate yog siv los ua tus neeg sawv cev hauv cov khoom noj khoom haus ntxiv rau rum, brandy, thiab whiskey, nrog rau hauv cov nplaum, cov khoom siv tu, kev tu tus kheej, thiab cov khoom siv tshuaj pleev ib ce, cov roj nplua nyeem, cov xim ziab sai xws li lacquers, lub cav tsheb coatings, rooj tog zaum. , industrial coatings (low boiling point), inks, resins, roj, thiab cov khoom siv hluav taws xob.Cov xim, coatings, tshuaj pleev ib ce, textiles, thiab automotive sectors yog thawj kawg kev lag luam rau cov khoom no.
Carbonylation yog ib txoj hauv kev siv hauv kev lag luam.Cov pa roj carbon monoxide substrates tau coj los ua ke hauv cov tshuaj tiv thaiv no.Methanol yog hlawv nrog acetic acid nyob rau hauv lub xub ntiag ntawm sulfuric acid los ua methyl acetate.
Lub esterification ntawm methanol thiab acetic acid nyob rau hauv lub xub ntiag ntawm ib tug muaj zog acid yog lwm txoj kev ntawm synthesis.Cov txheej txheem no kuj tseem siv cov sulfuric acid ua ib qho catalyst.
