Iimpawu zeMveliso:
I-1.I-acetate ye-Ethyl i-hydrolysed ngokulula, kwaye iphinde ifakwe i-hydrolysed ngokuthe ngcembe ukwenza i-acetic acid kunye ne-ethanol phambi kwamanzi kwindawo yokushisa. Ukongezwa kwezixa ze-asidi okanye isiseko kunokukhuthaza ukusabela kwe-hydrolysis. I-Ethyl acetate inokuphinda ifumane i-alcoholsis, i-ammonolysis, i-ester exchange, ukunciphisa kunye nezinye iimpendulo eziqhelekileyo zeester jikelele. Idibanisa ngokwayo phambi kwesinyithi se-sodium ukwenza i-3-hydroxy-2-butanone okanye i-ethyl acetoacetate; isabela kunye ne-reagent ye-Grignard ukwenza i-ketone, kwaye ukusabela okungaphezulu kunika utywala obuphezulu. I-acetate ye-Ethyl izinzile ngokushisa kwaye ihlala ingatshintshi xa ishushu kwi-290 ° C kwiiyure ze-8-10. Ibola ibe yi-ethylene kunye ne-acetic acid xa idluliselwe kumbhobho wentsimbi obomvu-oshushu, kwi-hydrogen, i-carbon monoxide, i-carbon dioxide, i-acetone kunye ne-ethylene ngomgubo we-zinc oshushu ukuya kwi-300 ~ 350 ° C, kwaye emanzini, i-ethylene, i-carbon dioxide kunye ne-acetone. i-aluminiyam oxide ephelelwe ngamanzi kwi-360°C. I-Ethyl acetate ichithwa yi-ultraviolet irradiation ukuvelisa i-55 yepesenti ye-carbon monoxide, i-14 ipesenti ye-carbon dioxide kunye ne-31 yeepesenti ze-hydrogen okanye i-methane, eziyi-gases ezinokutsha. Ukusabela nge-ozone kuvelisa i-acetaldehyde kunye ne-acetic acid. I-gaseous hydrogen halides isabela nge-ethyl acetate ukwenza i-ethyl halide kunye ne-acetic acid. I-Hydrogen iodide yeyona isebenzayo, ngelixa i-hydrogen chloride idinga uxinzelelo lokubola kwiqondo lokushisa, kwaye ifudunyezwe kwi-150 ° C kunye ne-phosphorus pentachloride ukwenza i-chloroethane kunye ne-acetyl chloride. I-Ethyl acetate yenza ii-crystalline complexes ngeetyuwa zetsimbi. Ezi complexes zinyibilika kwi ethanol anhydrous kodwa hayi kwi ethyl acetate kwaye zifakwa emanzini ngokulula.
