Katundu:
1.Zofanana ndi butyl acetate.Imawola mpaka 1-butene, 2-butene, ethylene ndi propylene ikatenthedwa mpaka 500 ° C.Pamene sec-butyl acetate imadutsa mu ubweya wagalasi mumtsinje wa nitrogen pa 460 mpaka 473 ° C, 56% 1-butene, 43% 2-butene ndi 1% propylene amapangidwa.Ikatenthedwa mpaka 380 ° C pamaso pa thorium oxide, imawola kukhala haidrojeni, carbon dioxide, butene, sec-butanol ndi acetone.Mlingo wa hydrolysis wa sec-butyl acetate ndi wochepa.Pamene ammonolysis imapezeka muzitsulo zoledzeretsa zoledzeretsa kutentha kwa firiji, 20% imasinthidwa kukhala amide mu maola 120.Imachita ndi benzene pamaso pa boron trifluoride kupanga sec-butylbenzene.Pamene photo-chlorination ikuchitika, chlorobutyl acetate imapangidwa.Mwa iwo, 1-methyl-2 chloropropyl acetate amawerengera 66% ndipo ma isomers ena amakhala 34%.
2.Kukhazikika: Kukhazikika
3. Zinthu zoletsedwa:Wamphamvu oxidants, asidi amphamvu, maziko amphamvu
4. Polymerization ngozi:Non-polymerization
Ntchito Yogulitsa:
1.Mainly amagwiritsidwa ntchito mu lacquer solvents, thinners, zosiyanasiyana masamba mafuta ndi utomoni solvents.Amagwiritsidwanso ntchito popanga mapulasitiki ndi zonunkhira.Mafuta oletsa kugogoda.
2.Kugwiritsidwa ntchito ngati zosungunulira, mankhwala opangira mankhwala, omwe amagwiritsidwa ntchito pokonzekera zonunkhira
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,alkali ndi zidulo,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.
