Khoom Properties:
1.Zoo li butyl acetate. Decomposes rau 1-butene, 2-butene, ethylene thiab propylene thaum rhuab mus rau 500 ° C. Thaum sec-butyl acetate dhau los ntawm iav ntaub plaub hauv cov kwj ntawm nitrogen ntawm 460 txog 473 ° C, 56% 1-butene, 43% 2-butene thiab 1% propylene raug tsim. Thaum rhuab mus rau 380 ° C nyob rau hauv lub xub ntiag ntawm thorium oxide, nws decomposes rau hauv hydrogen, carbon dioxide, butene, sec-butanol thiab acetone. Tus nqi ntawm hydrolysis ntawm sec-butyl acetate yog me me. Thaum ammonolysis tshwm sim nyob rau hauv dilute cawv kua nyob rau hauv chav tsev kub, 20% hloov mus rau amide nyob rau hauv 120 teev. Nws reacts nrog benzene nyob rau hauv lub xub ntiag ntawm boron trifluoride los tsim sec-butylbenzene. Thaum yees duab-chlorination yog ua tiav, chlorobutyl acetate yog tsim. Ntawm lawv, 1-methyl-2 chloropropyl acetate account rau 66% thiab lwm yam isomers account rau 34%.
2.Stability: ruaj khov
3. Cov tshuaj txwv tsis pub:Muaj zog oxidants, muaj zog acids, lub hauv paus muaj zog
4.Polymerisation txaus ntshai:Tsis yog polymerisation
Khoom siv:
1.Mainly siv nyob rau hauv lacquer solvents, thinners, ntau yam zaub roj thiab resin solvents. Kuj tseem siv rau hauv plastics thiab kev tsim txuj lom. Gasoline antiknocking tus neeg saib xyuas.
2.Siv raws li cov kuab tshuaj, tshuaj reagents, siv rau hauv kev npaj cov txuj lom
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,alkalis thiab acids,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.Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
