Njenge-solvent eluhlaza, i-methyl acetate ikhululiwe ekuvinjweni futhi isetshenziswa njenge-solvent ephilayo ekukhiqizeni i-ester, ukugqoka, uyinki, upende, izinto zokunamathisela kanye nesikhumba;futhi isebenza njenge-ejenti ekhipha ugwebu yegwebu le-polyurethane, ngaphezu kwalokho, ingasetshenziswa futhi njengesithako samafutha namafutha ekukhiqizeni isikhumba sokwenziwa, iphunga, njll. Ekuphenduleni ukwanda kwesidingo semakethe, umthamo wesitshalo se-methyl acetate. ngi 210ktpa.

Iyini i-Methyl Acetate?
Ezingeni lokushisa elijwayelekile, i-methyl acetate ingamaphesenti angama-25 encibilika emanzini.Inoncibilika kakhulu emanzini emazingeni okushisa aphezulu.Lapho kukhona izisekelo ezinamandla ezinamanzi noma ama-asidi, i-methyl acetate ayizinzile.Nge-flashpoint engu--10 ° C kanye nenani elivuthayo elingu-3, livutha kakhulu.I-Methyl acetate iyi-solvent enobuthi obuphansi evame ukutholakala kumaglues nezikhiphi ze-nail polish.Ama-apula, amagilebhisi nobhanana kuphakathi kwezithelo ezine-methyl acetate.
Ukusetshenziswa Kwezimboni
Ukusabela kwe-carbonylation nge-methyl acetate ukukhiqiza i-acetic anhydride isetshenziswa embonini.Ibuye isetshenziswe njengesinyibilikisi kupende, iglue, i-nail polish, nezikhiphi ze-graffiti, kanye nezinto zokugcoba, ezimaphakathi, nezinsiza zokucubungula.
I-Methyl acetate nayo isetshenziswa njengekhemikhali emaphakathi ekukhiqizeni izinto zokunamathisela kanye neziqholo ze-cellulose, kanye nokuhlanganiswa kwe-chlorophacinone, i-diphacinone, i-fenfluramine, i-o-methoxy phenylacetone, i-p-methoxy phenylacetone, i-methyl cinnamate, i-methyl cyanopacetone, i-methyl cyanopacetone, i-methyl .
I-Methyl acetate isetshenziswa njenge-ejenti yokunambitheka ezithasiselweni zokudla ze-rum, i-brandy, ne-whisky, kanye nezinto ezinamathelayo, imikhiqizo yokuhlanza, ukunakekelwa komuntu siqu, kanye nemikhiqizo yezimonyo, izinto zokuthambisa, opende omisa ngokushesha njengama-lacquers, okokugqokwa kwezimoto, okokumboza ifenisha. , izimbotshana zezimboni (indawo yokubilisa ephansi), oyinki, izinhlaka, uwoyela, nemikhiqizo kagesi.Imikhakha kapende, okokuhlanganisa, izimonyo, izindwangu, nezimoto izimakethe eziyinhloko zale nto.
I-Carbonylation ingenye yezindlela ezisetshenziswa embonini.Ama-substrates e-carbon monoxide ahlanganiswa kulokhu kusabela.I-Methanol ishiswa nge-acetic acid phambi kwe-sulfuric acid ukwenza i-methyl acetate.
I-esterification ye-methanol ne-acetic acid phambi kwe-asidi eqinile kungenye indlela yokuhlanganiswa.Le nqubo ngokufanayo isebenzisa ukusetshenziswa kwe-sulfuric acid njenge-catalyst.
