Ibicuruzwa:
1.Ethyl acetate iroroshye hydrolysed, kandi nayo buhoro buhoro hydrolysed ikora aside irike na Ethanol imbere y'amazi mubushyuhe bwicyumba. Kwiyongera kwinshi kwa acide cyangwa base birashobora guteza hydrolysis reaction. Ethyl acetate irashobora kandi kwandura alcool, ammonolysis, guhana ester, kugabanuka nibindi bitekerezo rusange bya est est rusange. Iyegeranya ubwayo imbere yicyuma cya sodium kugirango ikore 3-hydroxy-2-butanone cyangwa Ethyl acetoacetate; ikora hamwe na reagent ya Grignard kugirango ikore ketone, kandi ikindi gisubizo gitanga inzoga za kaminuza. Ethyl acetate irahagaze neza kugirango ubushyuhe kandi ntigihinduka iyo hashyushye kuri 290 ° C mumasaha 8-10. Yangirika muri Ethylene na acide acike iyo inyuze mu miyoboro itukura ishyushye, muri hydrogène, monoxide ya karubone, dioxyde de carbone, acetone na Ethylene ikoresheje ifu ya zinc yashyutswe kugeza kuri 300 ~ 350 ° C, no mu mazi, Ethylene, dioxyde de carbone na acetone binyuze muri umwuma wa aluminium oxyde kuri 360 ° C. Ethyl acetate yangirika na ultraviolet irrasiyoya kugirango itange 55% monoxide ya karubone, 14% ya dioxyde de carbone na 31% hydrogène cyangwa metani, ni imyuka yaka umuriro. Imyitwarire ya ozone itanga acetaldehyde na acide acike. Hydrogen hydrogène halide ikora hamwe na Ethyl acetate kugirango ikore Ethyl halide na acide acike. Iyode ya hydrogène niyo ikora cyane, mugihe hydrogène chloride isaba umuvuduko wo kubora mubushyuhe bwicyumba, kandi igashyuha kugeza kuri 150 ° C hamwe na fosifore pentachloride kugirango ikore chloroethane na acetyl chloride. Ethyl acetate ikora ibintu bitandukanye bya kristalline hamwe numunyu wicyuma. Izi nganda zishonga muri Ethanol ya anhydrous ariko ntabwo iri muri Ethyl acetate kandi byoroshye hydrolysed mumazi.
2. Guhagarara: Birahamye
3.Ibintu bibujijwe: Okiside ikomeye, alkalis, aside
4.Polymerisation hazard: Non-polymerisation
Gusaba ibicuruzwa:
Irashobora gukoreshwa mu gushonga nitrocellulose, gucapa wino, amavuta namavuta, nibindi birashobora kandi gukoreshwa nkibikoresho fatizo byo gusiga amarangi, uruhu rwubukorikori, ibicuruzwa bya pulasitike, amarangi, imiti nibirungo, nibindi.
Inyandiko zibika ibicuruzwa:
1.Bika mububiko bukonje, buhumeka.
2.Komeza kure yumuriro nubushyuhe.
3.Ubushyuhe bwo kubika ntibugomba kurenga37° C.
4.Komeza ikintu gifunze.
5.Bigomba kubikwa bitandukanye na okiside,acide na alkalis,kandi ntigomba na rimwe kuvangwa.
6.Koresha ibikoresho biturika biturika kandi bihumeka.
7.Kubuza gukoresha ibikoresho bya mashini nibikoresho byoroshye kubyara ibishashi.
8.Ahantu ho guhunika hagomba kuba hafite ibikoresho byihutirwa byihutirwa nibikoresho byubuhungiro.
