Chii chinonzi Methyl Acetate?
Pakupisa kwakajairika, methyl acetate ine 25 muzana inonyungudika mumvura.Iine kunyungudika kwakanyanya mumvura pane tembiricha dzakakwirira.Muhupo hwemabhesi ane aqueous akasimba kana acids, methyl acetate haina kugadzikana.Nekupenya kwe -10 ° C uye kukosha kwekupisa kwe3, inopisa zvikuru.Methyl acetate ishoma-toxicity solvent inowanzo wanikwa mune glues uye zvipikiri zvekubvisa zvipikiri.Maapuro, mazambiringa, uye mabhanana ndezvimwe zvemichero ine methyl acetate.
Industrial Uses
Kuita kwecarbonylation nemethyl acetate kugadzira acetic anhydride inoshandiswa muindasitiri.Inoshandiswawo sechinhu chinonyungudutsa mupende, glue, nail polish, uye graffiti removers, pamwe chete nemafuta ekuzora, epakati, uye ekugadzirisa aids.
Methyl acetate inoshandiswawo sekemikari yepakati mukugadzirwa kwe cellulose adhesives uye pefiyumu, pamwe nekugadzirwa kwe chlorophacinone, diphacinone, fenfluramine, o-methoxy phenylacetone, p-methoxy phenylacetone, methyl cinnamate, methyl cyanopacetone, uye methylphenylacetone, .
Methyl acetate inoshandiswa sechinhu chinonhuwira mune zvekudya zvinowedzera rum, brandy, uye whisky, pamwe nemunamatidza, zvigadzirwa zvekuchenesa, kuchengetedza kwevanhu, uye zvigadzirwa zvekuzora, mafuta ekuzora, kukurumidza kuomesa pendi senge lacquers, majasi emota, machira efenicha. , machira emaindasitiri (yakaderera kubikira nzvimbo), ingi, resin, oiri, uye zvigadzirwa zvemagetsi.Iyo pendi, machira, zvizorwa, machira, uye zvikamu zvemotokari ndiwo misika yekupedzisira yechinhu ichi.
Carbonylation ndiyo imwe nzira inoshandiswa mumaindasitiri.Carbon monoxide substrates inounzwa pamwechete mukuita uku.Methanol inopiswa neacetic acid pamberi pe sulfuric acid kugadzira methyl acetate.
Iyo esterification ye methanol uye acetic acid muhupo hweasidhi yakasimba ndiyo imwe nzira yekubatanidza.Kuita uku kunoshandisawo kushandiswa kwe sulfuric acid sechinhu chinokonzeresa.
