Nkumuti wicyatsi, methyl acetate isonewe kubuzwa kandi ikoreshwa nkibishishwa kama mugukora ester, gutwikira, wino, irangi, ibifata nimpu;kandi ikora nk'ifuro ifata ifuro rya polyurethane, ikindi, irashobora kandi gukoreshwa nk'ikuramo amavuta n'amavuta mu gukora uruhu rw’ibihimbano, impumuro nziza, n'ibindi. Mu rwego rwo kongera ibicuruzwa bikenewe ku isoko ， ubushobozi bw'uruganda rwa methyl acetate ni 210ktpa.
Wige byinshi kuri Methyl Acetate
Methyl Acetate ni iki?
Ku bushyuhe busanzwe, methyl acetate irashobora gushonga 25% mumazi.Ifite imbaraga nyinshi zo gushonga mumazi kubushyuhe bwinshi.Imbere yibishingwe byamazi bikomeye cyangwa acide, methyl acetate ntabwo ihagaze.Hamwe na flash point ya -10 ° C hamwe numuriro wa 3, irashya cyane.Methyl acetate ni uburozi buke bukunze kuboneka muri kole no kuvanaho imisumari.Pome, inzabibu, n'ibitoki biri mu mbuto zirimo methyl acetate.
Gukoresha Inganda
Imyitwarire ya carbonylation hamwe na methyl acetate kugirango itange acide anhydride ikoreshwa mu nganda.Irakoreshwa kandi nk'igishishwa mu gusiga amarangi, kole, imisumari, hamwe no gukuramo graffiti, hamwe n'amavuta yo kwisiga, abahuza, hamwe n'ibikoresho byo gutunganya.
Methyl acetate ikoreshwa kandi nk'imiti igabanya ubukana mu gukora ibibyimba bya selile na parufe, hamwe na synthesis ya chlorophacinone, diphacinone, fenfluramine, o-mikorerexy phenylacetone, p-méthoxy fenilacetone, methyl cinnamate, methyl cyanoacetate, methyldopa. .
Methyl acetate ikoreshwa nkibintu byongera ibiryo byongeweho ibiryo bya rum, brandi, na whiski, ndetse no mubifata neza, ibicuruzwa bisukura, kwita kumuntu ku giti cye, nibisiga amavuta yo kwisiga, amavuta, amarangi yumisha vuba nka lacquer, ibinyabiziga bitwikiriye ibinyabiziga, ibikoresho byo mu nzu. , inganda zikora inganda (aho zitetse), wino, resin, amavuta, nibicuruzwa bya elegitoroniki.Irangi, impuzu, amavuta yo kwisiga, imyenda, hamwe nimirenge niyo soko ryambere ryanyuma kuriyi ngingo.
Carbonylation nuburyo bumwe bukoreshwa mu nganda.Carbone monoxide substrates ihurizwa hamwe muribi bitekerezo.Methanol yatwitswe na acide acike imbere ya acide sulfurike kugirango ikore methyl acetate.
Esterification ya methanol na acide acike imbere ya acide ikomeye nubundi buryo bwa synthesis.Ubu buryo nabwo bukoresha ikoreshwa rya acide sulfurike nka catalizator.
