Katundu:
1.Ethyl acetate ndi hydrolysed mosavuta, komanso pang'onopang'ono hydrolysed kupanga asidi asidi ndi ethanol pamaso pa madzi kutentha firiji.Kuphatikizika kwa kuchuluka kwa asidi kapena m'munsi kumatha kulimbikitsa hydrolysis.Ethyl acetate imathanso kukhala ndi alcoholysis, ammonolysis, ester exchange, kuchepetsa ndi zina zomwe zimachitika kawirikawiri zama esters ambiri.Imadzipiritsa yokha pamaso pa sodium zitsulo kupanga 3-hydroxy-2-butanone kapena ethyl acetoacetate;imakhudzidwa ndi reagent ya Grignard kupanga ketone, ndipo kuchita kwina kumapereka mowa wapamwamba.Ethyl acetate imakhala yokhazikika pakutentha ndipo imakhalabe yosasinthika ikatenthedwa pa 290 ° C kwa maola 8-10.Imawola kukhala ethylene ndi acetic acid ikadutsa chitoliro chachitsulo chofiyira, kulowa hydrogen, carbon monoxide, carbon dioxide, acetone ndi ethylene kudzera mu zinc ufa wotenthedwa mpaka 300 ~ 350 ° C, ndi kulowa m'madzi, ethylene, carbon dioxide ndi acetone kudzera. aluminiyamu oxide ya dehydrated pa 360 ° C.Ethyl acetate imawonongeka ndi kuwala kwa ultraviolet kuti ipange 55 peresenti ya carbon monoxide, 14 peresenti ya carbon dioxide ndi 31 peresenti ya haidrojeni kapena methane, yomwe ndi mpweya woyaka moto.Kuchita ndi ozoni kumapanga acetaldehyde ndi asidi asidi.Gaseous hydrogen halides amachita ndi ethyl acetate kupanga ethyl halide ndi acetic acid.Iodide ya haidrojeni ndi yomwe imagwira ntchito kwambiri, pomwe hydrogen chloride imafuna kukakamizidwa kuti iwonongeke kutentha kwa chipinda, ndipo imatenthedwa mpaka 150 ° C ndi phosphorous pentachloride kupanga chloroethane ndi acetyl chloride.Ethyl acetate imapanga mitundu yosiyanasiyana ya makristalo okhala ndi mchere wachitsulo.Ma complexeswa amasungunuka mu ethanol ya anhydrous koma osati mu ethyl acetate ndipo amasungunuka mosavuta m'madzi.
2.Kukhazikika: Kukhazikika
3.Zinthu zoletsedwa: Zowonjezera zamphamvu, ma alkali, ma acid
4.Polymerization ngozi: Kupanda polymerization
Ntchito Yogulitsa:
Itha kugwiritsidwa ntchito pakusungunula nitrocellulose, inki yosindikiza, mafuta ndi mafuta, etc. Itha kugwiritsidwanso ntchito ngati zopangira utoto, zikopa zopanga, pulasitiki, utoto, mankhwala ndi zonunkhira, etc.
Zolemba Zosungira:
1.Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi moto ndi gwero la kutentha.
3.Kutentha kosungirako sikuyenera kupitirira37°C.
4.Sungani chidebe chosindikizidwa.
5. Iyenera kusungidwa mosiyana ndi oxidizing agents,ma acid ndi alkalis,ndipo zisasokonezedwe.
6.Gwiritsani ntchito zounikira zosaphulika ndi mpweya wabwino.
7.Letsani kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kupanga zopsereza.
8.Malo osungiramo zinthu ayenera kukhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zogona.
