Njirimara ngwaahịa:
1.Ethyl acetate dị mfe hydrolysed, ma jiri nwayọọ nwayọọ na-emepụta acetic acid na ethanol n'ihu mmiri na ụlọ okpomọkụ. Mgbakwunye nke ọnụọgụ acid ma ọ bụ isi nwere ike ịkwalite mmeghachi omume hydrolysis. Ethyl acetate nwekwara ike ịnweta alcoholysis, ammonolysis, ester mgbanwe, mbelata na mmeghachi omume ndị ọzọ na-emekarị nke esters izugbe. Ọ na-ejikọta onwe ya na ọnụnọ sodium metal iji mepụta 3-hydroxy-2-butanone ma ọ bụ ethyl acetoacetate; ọ na-emeghachi omume na reagent Grignard na-emepụta ketone, mmeghachi omume ọzọ na-enye mmanya atọ. Ethyl acetate kwụsiri ike ka ọ na-ekpo ọkụ ma na-agbanwe agbanwe mgbe ọ na-ekpo ọkụ na 290 Celsius maka awa 8-10. Ọ decomposes n'ime ethylene na acetic acid mgbe gafere site na-acha uhie uhie ígwè ọkpọkọ, n'ime hydrogen, carbon monoxide, carbon dioxide, acetone na ethylene site zinc ntụ ntụ kpụ ọkụ n'ọnụ ruo 300 ~ 350 ° C, na n'ime mmiri, ethylene, carbon dioxide na acetone site. aluminum oxide dehydrated na 360ºC. Ethyl acetate na-emebi site na ultraviolet irradiation iji mepụta 55 pasent carbon monoxide, 14 pasent carbon dioxide na 31 pasent hydrogen ma ọ bụ methane, nke bụ gas na-ere ọkụ. Mmeghachi omume na ozone na-emepụta acetaldehyde na acetic acid. Gaseous hydrogen halides na-emeghachi omume na ethyl acetate iji mepụta ethyl halide na acetic acid. Hydrogen iodide bụ ihe na-emeghachi omume nke ọma, ebe hydrogen chloride na-achọ nrụgide ka ọ daa n'ime ụlọ, ma na-ekpo ọkụ ruo 150 Celsius na pentachloride phosphorus iji mepụta chloroethane na acetyl chloride. Ethyl acetate na-etolite ogige kristal dị iche iche na nnu ígwè. Ụlọ ndị a na-agbaze na ethanol anhydrous mana ọ bụghị na ethyl acetate ma na-agbaze ya ngwa ngwa na mmiri.
