Ma keʻano he'ōmaʻomaʻo'ōmaʻomaʻo, hoʻokuʻuʻia ka methyl acetate mai ka palena a hoʻohanaʻia ma keʻano he mea hoʻoheheʻe organik i ka hanaʻana i ka ester, ka uhi, ka'īnika, ka pena, nā mea hoʻopili a me kaʻili;a hana e like me ka huʻihuʻi no ka polyurethane foam, ʻoi aku, hiki ke hoʻohana ʻia ma ke ʻano he extractant no ka ʻaila a me ka momona i ka hana ʻana i ka ʻili artificial, ka ʻala, a me nā mea ʻē aʻe. he 210ktpa.
E aʻo hou e pili ana i ka Methyl Acetate
He aha ka Methyl Acetate?
Ma ka mahana maʻamau, ʻo ka methyl acetate he 25 pakeneka hiki ke hoʻoheheʻe ʻia i ka wai.He ʻoi aku ka nui o ka hoʻoheheʻe ʻana i ka wai ma nā wela kiʻekiʻe.Ma ke alo o nā kumu wai ikaika a i ʻole nā waikawa, ʻaʻole paʻa ka methyl acetate.Me kahi flash point o -10° C a me ka waiwai flammability o 3, he mea wela loa ia.ʻO ka Methyl acetate kahi mea hoʻoheheʻe haʻahaʻa haʻahaʻa i loaʻa pinepine ʻia i loko o nā glues a me nā mea hoʻohemo nail polish.ʻO nā ʻāpala, nā hua waina, a me ka maiʻa kekahi o nā hua i loaʻa i ka methyl acetate.
Hoohana Hana Hana
Hoʻohana ʻia ka hopena o ka carbonylation me ka methyl acetate e hana ai i ka acetic anhydride i ka ʻoihana.Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe i ka pena, ke kāpili, ka nail polish, a me nā mea wehe graffiti, a me nā lubricants, intermediates, a me nā mea kōkua.
Hoʻohana ʻia ʻo Methyl acetate ma ke ʻano he mea kemika i ka hana ʻana i nā mea hoʻopili cellulose a me nā mea ʻala, a me ka synthesis o chlorophacinone, diphacinone, fenfluramine, o-methoxy phenylacetone, p-methoxy phenylacetone, methyl cinnamate, methylcyanoacetate, a me methylphenydopacetate. .
Hoʻohana ʻia ʻo Methyl acetate ma ke ʻano he mea ʻono i nā mea hoʻohui meaʻai no ka lama, brandy, a me ka whisky, a me nā mea hoʻopili, nā huahana hoʻomaʻemaʻe, mālama pilikino, a me nā mea hoʻonaninani, nā lubricants, nā pena maloʻo wikiwiki e like me nā lacquers, nā kaʻa kaʻa kaʻa, nā mea hoʻonaninani. , nā uhi hana ʻoihana (kahi hoʻolapalapa haʻahaʻa), inks, resins, aila, a me nā huahana uila.ʻO ka pena, nā uhi, nā mea hoʻonaninani, nā textiles, a me nā ʻāpana automotive nā mākeke hope mua no kēia mea.
ʻO ka carbonylation kekahi ala i hoʻohana ʻia i ka ʻoihana.Hoʻohui pū ʻia nā substrates carbon monoxide i kēia mau hopena.Hoʻopau ʻia ka Methanol me ka acetic acid i mua o ka sulfuric acid e hana i ka methyl acetate.
ʻO ka esterification o ka methanol a me ka acetic acid i mua o kahi waikawa ikaika kekahi ala o ka synthesis.Hoʻohana pū kēia kaʻina hana i ka hoʻohana ʻana i ka sulfuric acid ma ke ʻano he catalyst.
