Njenge-solvent eluhlaza, i-methyl acetate ikhululiwe kwisithintelo kwaye isetyenziswe njenge-solvent ye-organic kwi-ester yokuvelisa, i-coating, inki, ipeyinti, i-adhesives kunye nesikhumba;kwaye isebenza njengearhente yogwebu lwe-polyurethane ugwebu, nangaphezulu, isenokusetyenziswa njengesixhobo sokutsalwa kweoli kunye negrisi kwimveliso yesikhumba sokwenziwa, ivumba elimnandi, njalo njalo. yi 210ktpa.

Yintoni iMethyl Acetate?
Kwiqondo lokushisa eliqhelekileyo, i-methyl acetate i-25 yepesenti enyibilikayo emanzini.Inonyibiliko olukhulu kakhulu emanzini kumaqondo obushushu aphezulu.Xa kukho iziseko ezinamandla ezinamanzi okanye i-acids, i-methyl acetate ayizinzile.Nge-flashpoint ye--10 ° C kunye nexabiso elivuthayo le-3, livutha kakhulu.I-Methyl acetate sisinyibilikisi esinetyhefu ephantsi ehlala ifumaneka kwiiglu kunye nezisusa ze-nail polish.Ama-apile, iidiliya, neebhanana ziphakathi kweziqhamo ezinemethyl acetate.
Usetyenziso lwemizi-mveliso
Ukusabela kwe-carbonylation nge-methyl acetate ukuvelisa i-acetic anhydride isetyenziswa kwishishini.Ikwasetyenziswa njengesinyibilikisi kwipeyinti, iglu, ipolishi yezikhonkwane, kunye nezisusi zegraffiti, kunye nezinto zokuthambisa, izibilini, kunye nezixhobo zokulungisa.
I-Methyl acetate iphinda isetyenziswe njengekhemikhali ephakathi kwimveliso ye-cellulose adhesives kunye neziqholo, kunye ne-synthesis ye-chlorophacinone, i-diphacinone, i-fenfluramine, i-o-methoxy phenylacetone, i-p-methoxy phenylacetone, i-methyl cinnamate, i-methyl cyanoacetone, i-methyl cyanopacetone, i-methyl cyanopacetone, .
I-Methyl acetate isetyenziswa njenge-flavoring agent kwizongezo zokutya kwi-rum, i-brandy, kunye ne-whisky, kunye ne-adhesives, iimveliso zokucoca, ukunakekelwa komntu, kunye neemveliso zokuthambisa, i-lubricants, iipeyinti ezomisa ngokukhawuleza njenge-lacquers, iingubo zemoto, iingubo zefenitshala. , iingubo zamashishini (indawo yokubilisa ephantsi), i-inki, ii-resin, i-oyile kunye neemveliso ze-elektroniki.Ipeyinti, izinto zokuthambisa, izinto zokuthambisa, ezilukiweyo, kunye namacandelo eemoto zezona ntengiso ziphambili zale nto.
ICarbonylation yenye yeendlela ezisetyenziswa kwishishini.Iisubstrates zeCarbon monoxide zidityaniswa ndawonye kwezi ntshukumo.I-Methanol itshiswa nge-acetic acid phambi kwe-sulfuric acid ukwenza i-methyl acetate.
I-esterification ye-methanol kunye ne-acetic acid phambi kwe-asidi eqinile yenye indlela yokudibanisa.Le nkqubo ngokufanayo isebenzisa ukusetyenziswa kwe-asidi yesulfuric njenge-catalyst.
