I le avea ai o se solvent lanu meamata, o le methyl acetate e tuusaunoaina mai le faʻatapulaʻaina ma faʻaaogaina e avea ma solvent organic i le gaosiga o le ester, paʻu, vaitusi, vali, faʻapipiʻi ma paʻu;ma galue e pei o le foaming agent mo polyurethane foam, e le gata i lea, e mafai foi ona faʻaaogaina e avea o se suauʻu ma gaʻo i le gaosiga o paʻu paʻu, manogi, ma isi. e 210ktpa.
Aoao atili e uiga i le Methyl Acetate
O le a le Methyl Acetate?
I le vevela masani, o le methyl acetate e 25 pasene soluble i le vai.E sili atu lona solubility i le vai i le maualuga o le vevela.I le i ai o ni fa'avae vai malolosi po'o ni vaila'au, o le methyl acetate e le mautu.Faʻatasi ai ma le moli uila o le -10° C ma le tau o le mu o le 3, e matua mumu lava.O le Methyl acetate ose vaisu e maualalo le oona e masani ona maua i kelu ma fa'a'ese'ese fao.O apu, vine, ma faʻi o nisi ia o fua o loʻo iai le methyl acetate.
Fa'aaogāga Alamanuia
Ole tali ole carbonylation ma le methyl acetate e gaosia ai le acetic anhydride e faʻaaogaina ile alamanuia.E fa'aogaina fo'i e fai ma solu i vali, kelu, fao fao, ma graffiti aveese, fa'apea fo'i lubricants, intermediates, ma fesoasoani fa'agaioia.
Methyl acetate o loʻo faʻaaogaina foi e avea o se vailaʻau vavalo i le gaosiga o mea faʻapipiʻi cellulose ma mea manogi, faʻapea foʻi ma le faʻaogaina o le chlorophacinone, diphacinone, fenfluramine, o-methoxy phenylacetone, p-methoxy phenylacetone, methyl cinnamate, methylcyanoacetate, ma methylphenydopacetate. .
Methyl acetate o loʻo faʻaaogaina e avea o se mea e faʻamalieina ai meaʻai mo le rum, brandy, ma le whisky, faʻapea foʻi ma mea faʻapipiʻi, mea faʻamamaina, tausiga o le tagata lava ia, ma mea faʻalelei, lubricants, vali faʻamago vave e pei o lacquers, paʻu taʻavale afi, meafale faʻapipiʻi. , fa'alavalava fa'apisinisi (maualalo le fa'apuna), vaitusi, resini, suau'u, ma mea fa'aeletoroni.O vali, fa'alavalava, mea teuteu, 'ie, ma vaega tau ta'avale o fa'atauga pito sili ia mo lenei mea.
Carbonylation o se tasi auala e faʻaaogaina i alamanuia.O mea'ai o le carbon monoxide e fa'apotopoto fa'atasi i nei gaioiga.E susunuina le Methanol i le acetic acid i luma o le sulfuric acid e fai ai le methyl acetate.
O le esterification o le methanol ma le acetic acid i le i ai o se malosi malosi o se isi auala o le faʻapipiʻiina.O lenei faiga e fa'aaogaina ai le fa'aogaina o le sulfuric acid e fai ma fa'amalosi.
