Āhuatanga Hua:
1.Ko te Ethyl acetate he ngawari te whakamaarama, me te whakamaarama hoki ki te hanga i te waikawa acetate me te waihā i te aroaro o te wai i te pāmahana rūma. Ko te taapiri i te nui o te waikawa, te turanga ranei ka whakatairanga i te tauhohenga hauwai. Ka taea hoki e te Ethyl acetate te mate waipiro, te ammonolysis, te whakawhiti ester, te whakaheke me etahi atu tauhohenga noa o nga esters whanui. Ka whakapoapoa noa i te aroaro o te konutai konutai hei hanga 3-hydroxy-2-butanone, ethyl acetoacetate ranei; ka tauhohe ki te tauhohenga a Grignard ki te hanga ketone, me te tauhohenga ka puta he waipiro tuatoru. Ko te Ethyl acetate he ahua pumau ki te wera me te noho kore rereke ina whakamahana i te 290°C mo nga haora 8-10. Ka pirau ki roto i te ethylene me te waikawa acetic ka tukuna i roto i te putorino rino wera-whero, ki roto i te hauwai, te waro monoxide, te hauhā, te acetone me te ethylene na roto i te paura konutea whakamahana ki te 300~350°C, ka uru ki te wai, ethylene, carbon dioxide me te acetone ma roto. konumohe waikura waikura i te 360°C. Ko te Ethyl acetate ka tihorea e te irarangi ultraviolet hei whakaputa i te 55 paiheneti waro monoxide, 14 paiheneti te waro hauhaa me te 31 paiheneti hauwai, mewaro ranei, he hau mura. Ko te tauhohenga me te ozone ka puta te acetaldehyde me te waikawa acetic. Ka tauhohe nga hauwai hauwai ki te ethyl acetate ki te hanga ethyl halide me te waikawa acetate. Ko te iodide hauwai te tino hohenga, engari me pehanga te hauwai hauwai ki te pirau i te pāmahana rūma, ka whakamahana ki te 150°C me te phosphorus pentachloride hei hanga chloroethane me te acetyl chloride. Ka hangaia e te Ethyl acetate nga momo matatini tioata me nga tote whakarewa. He wairewa enei matatini i roto i te waiwaro anhydrous engari kaore i roto i te ethyl acetate, ka ngawari ki te waiwai ki te wai.
2.Stability: Stable
3.Matū kua whakakorehia: Te kaha o te waikura, te kawakore, te waikawa
4.Te whakakoioratanga morearea: Kore-raurautanga
Taupānga Hua:
Ka taea te whakamahi ki te whakakore i te nitrocellulose, te waituhi tuhi, te hinu me te hinu, me etahi atu Ka taea hoki te whakamahi hei rauemi mata mo te peita, te hiako horihori, nga hua kirihou, nga waikano, nga rongoa me nga mea kakara, me era atu.
Nga Tuhipoka Rokiroki Hua:
1. Rokiroki i roto i te whare putunga hauhautanga, whai hau.
2.Kia matara atu i te ahi me te puna wera.
3.Ko te pāmahana rokiroki kaua e nui ake37°C.
4. Kia hiritia te ipu.
5.Me penapena motuhake mai i nga kaihoko oxidizing,waikawa me te kawakore,a kaua rawa e uru.
6.Use rama pahū-tohu me whakaurunga ventilation.
7. Ka aukati i te whakamahi i nga taputapu miihini me nga taputapu ngawari ki te whakaputa korakora.
8.Ko te waahi rokiroki me whakauru ki nga taputapu maimoatanga ohorere pakaru me nga taonga whakaruru tika.
