Monga zosungunulira zobiriwira, methyl acetate imamasulidwa ku chiletso ndipo imagwiritsidwa ntchito ngati organic solvent mu kupanga ester, zokutira, inki, utoto, zomatira ndi zikopa;ndipo imakhala ngati thovu la thovu la polyurethane, kupitilira apo, itha kugwiritsidwanso ntchito ngati chopangira mafuta ndi mafuta popanga zikopa, kununkhira, ndi zina zotero. ndi 210kt.
Dziwani zambiri za Methyl Acetate
Kodi Methyl Acetate ndi chiyani?
Pa kutentha kwabwino, methyl acetate ndi 25 peresenti yosungunuka m'madzi.Ili ndi kusungunuka kwakukulu m'madzi pa kutentha kwakukulu.Pamaso pa maziko amadzi amphamvu kapena ma acid, methyl acetate ndi yosakhazikika.Ndi flashpoint ya -10 ° C ndi mtengo woyaka moto wa 3, ndi woyaka kwambiri.Methyl acetate ndi chosungunulira chotsika kawopsedwe chomwe nthawi zambiri chimapezeka mu zomatira ndi zochotsa misomali.Maapulo, mphesa, ndi nthochi ndi zina mwa zipatso zomwe zili ndi methyl acetate.
Zogwiritsa Ntchito Zamakampani
Zomwe carbonylation ndi methyl acetate kupanga acetic anhydride imagwiritsidwa ntchito m'makampani.Amagwiritsidwanso ntchito ngati zosungunulira mu utoto, zomatira, kupukuta misomali, ndi zochotsera graffiti, komanso mafuta opangira mafuta, zolumikizira, ndi zothandizira kukonza.
Methyl acetate imagwiritsidwanso ntchito ngati mankhwala apakatikati popanga zomatira za cellulose ndi mafuta onunkhira, komanso kaphatikizidwe ka chlorophacinone, diphacinone, fenfluramine, o-methoxy phenylacetone, p-methoxy phenylacetone, methyl cinnamate, methyl cyanopacetone, methyl cyanopacetone, ndi methylphenylacetone, .
Methyl acetate imagwiritsidwa ntchito ngati chokometsera pazowonjezera zakudya za ramu, brandy, ndi whisky, komanso zomatira, zotsukira, chisamaliro chamunthu, ndi zodzoladzola, mafuta opaka, utoto wowuma mwachangu monga lacquers, zokutira zamagalimoto, zokutira mipando. , zokutira zamakampani (zotsika zowira), inki, utomoni, mafuta, ndi zinthu zamagetsi.Magawo a utoto, zokutira, zodzola, zovala, ndi magalimoto ndiye misika yayikulu kwambiri yazinthu izi.
Carbonylation ndi njira imodzi yomwe imagwiritsidwa ntchito m'makampani.Mpweya wa carbon monoxide umasonkhanitsidwa pamodzi muzochitazi.Methanol amawotchedwa ndi acetic acid pamaso pa sulfuric acid kuti apange methyl acetate.
The esterification wa methanol ndi asidi asidi pamaso pa asidi amphamvu ndi njira ina kaphatikizidwe.Njira imeneyi imagwiritsanso ntchito sulfuric acid ngati chothandizira.
