Khoom Properties:
1.Ethyl acetate yog yooj yim hydrolysed, thiab kuj maj mam hydrolysed los tsim acetic acid thiab ethanol nyob rau hauv lub xub ntiag ntawm dej nyob rau hauv chav tsev kub.Qhov sib ntxiv ntawm cov kua qaub lossis cov hauv paus tuaj yeem txhawb nqa cov tshuaj tiv thaiv hydrolysis.Ethyl acetate tuaj yeem ua rau haus cawv, ammonolysis, ester pauv, txo qis thiab lwm yam kev cuam tshuam ntawm cov esters.Nws condenses los ntawm nws tus kheej nyob rau hauv lub xub ntiag ntawm sodium hlau los ua 3-hydroxy-2-butanone los yog ethyl acetoacetate;Nws reacts nrog Grignard's reagent los tsim ketone, thiab ntxiv cov tshuaj tiv thaiv muab tertiary cawv.Ethyl acetate yog qhov ruaj khov rau cov cua sov thiab tseem tsis hloov thaum rhuab ntawm 290 ° C rau 8-10 teev.Nws decomposes rau hauv ethylene thiab acetic acid thaum dhau los ntawm liab-kub hlau yeeb nkab, rau hauv hydrogen, carbon monoxide, carbon dioxide, acetone thiab ethylene los ntawm zinc hmoov rhuab mus rau 300 ~ 350 ° C, thiab mus rau hauv dej, ethylene, carbon dioxide thiab acetone los ntawm dehydrated aluminium oxide ntawm 360 ° C.Ethyl acetate yog decomposed los ntawm ultraviolet irradiation los tsim 55 feem pua carbon monoxide, 14 feem pua carbon dioxide thiab 31 feem pua hydrogen los yog methane, uas yog flammable gases.Cov tshuaj tiv thaiv ozone tsim acetaldehyde thiab acetic acid.Gaseous hydrogen halides teb nrog ethyl acetate los tsim ethyl halide thiab acetic acid.Hydrogen iodide yog qhov reactive tshaj plaws, thaum hydrogen chloride yuav tsum tau siab kom decompose nyob rau hauv chav tsev kub, thiab yog rhuab mus rau 150 ° C nrog phosphorus pentachloride los tsim chloroethane thiab acetyl chloride.Ethyl acetate tsim ntau yam crystalline complexes nrog hlau ntsev.Cov complexes yog soluble nyob rau hauv anhydrous ethanol tab sis tsis nyob rau hauv ethyl acetate thiab yog yooj yim hydrolysed nyob rau hauv dej.
2.Stability: ruaj khov
3. Cov tshuaj txwv tsis pub: muaj zog oxidants, alkalis, acids
4.Polymerisation txaus ntshai: Tsis yog-polymerisation
Khoom siv:
Nws tuaj yeem siv los ua kom yaj nitrocellulose, luam ntawv number case, roj thiab roj, thiab lwm yam. Nws tuaj yeem siv los ua cov khoom siv raw rau cov xim, tawv tawv, cov khoom yas, dyestuffs, tshuaj thiab cov txuj lom, thiab lwm yam.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
3.Qhov kub cia yuav tsum tsis txhob tshaj37°C.
4. Khaws lub thawv kaw.
5.Nws yuav tsum tau muab cais los ntawm cov neeg ua haujlwm oxidizing,acids thiab alkalis,thiab yuav tsum tsis txhob sib xyaw.
6.Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab cov chaw ua pa.
7. Txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov pob zeb.
8.Qhov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev thiab cov khoom siv vaj tse tsim nyog.
