Hei whakarewa kaakaariki, ka whakakorehia te methyl acetate mai i te aukati, ka whakamahia hei whakarewa waro i roto i te hanga ester, paninga, mangumangu, peita, whakapiri me te hiako;me te mahi hei kaihoko pahuka mo te pahuka i te polyurethane, i tua atu, ka taea hoki te whakamahi hei tango mo te hinu me te hinu i roto i te hanga hiako horihori, kakara, me etahi atu. he 210ktpa.
Ako atu mo Methyl Acetate
He aha te Methyl Acetate?
I te pāmahana noa, ko te methyl acetate he 25 paiheneti te wairewa ki te wai.He nui ake te wairewa i roto i te wai i te pāmahana teitei ake.I te aroaro o nga turanga wai kaha, waikawa ranei, karekau te methyl acetate.Ma te tohu rama -10° C me te uara muramura o te 3, he tino muramura.Ko te Methyl acetate he whakarewa iti-paitini ka kitea i roto i nga kapia me te tango i nga whao.Ko nga aporo, karepe, me nga panana kei roto i nga hua kei roto te methyl acetate.
Whakamahinga Ahumahi
Ko te tauhohenga o te waro waro me te methyl acetate ki te whakaputa anhydride acetic ka whakamahia i roto i te umanga.Ka whakamahia ano hei whakarewa i roto i te peita, te kapia, te whao, me te tango graffiti, me te whakahinuhinu, te takawaenga, me nga awhina tukatuka.
Ka whakamahia ano te Methyl acetate hei takawaenga matū i roto i te hanga o te cellulose adhesives me te hinu kakara, me te whakahiato o te chlorophacinone, diphacinone, fenfluramine, o-methoxy phenylacetone, p-methoxy phenylacetone, methyl cinnamate, methylcyanoacetate, me te methylphenylacetone. .
Ka whakamahia te Methyl acetate hei kai reka i roto i nga taapiri kai mo te rama, parani, me te whisky, tae atu ki nga taapiri, nga hua horoi, te tiaki whaiaro, me nga hua whakapaipai, nga hinu, nga peita tere-maroke penei i te lacquers, te whakakikorua o nga motuka motuka, nga taputapu taputapu. , nga whakakikoruatanga ahumahi (he iti te waahi kohua), te waituhi, te kapia, te hinu, me nga hua hiko.Ko te peita, te paninga, te whakapaipai, te kakano, me nga waahanga miihini ko nga maakete mutunga tuatahi mo tenei taonga.
Ko te Carbonylation tetahi tikanga e whakamahia ana i roto i te ahumahi.Ko nga taputapu waro monoxide ka whakakotahi i enei tauhohenga.Ka tahuna te Methanol ki te waikawa ahetiki i te aroaro o te waikawa sulfuric hei hanga methyl acetate.
Ko te esterification o te methanol me te waikawa acetic i te aroaro o te waikawa kaha tetahi atu huarahi o te whakahiato.Ka whakamahia ano e tenei tukanga te whakamahi i te waikawa sulfuric hei whakakorikori.
