Nā waiwai huahana:
1.Similar me ka butyl acetate.Decomposes i 1-butene, 2-butene, ethylene a me propylene ke wela a 500 °C.Ke hele ʻia ka sec-butyl acetate i loko o ka huluhulu aniani i loko o ke kahawai o ka nitrogen ma 460 a 473 ° C, hana ʻia ka 56% 1-butene, 43% 2-butene a me 1% propylene.Ke hoʻomehanaʻia i ka 380 ° C i mua o ka thorium oxide, hoʻoheheʻe ia i hydrogen, carbon dioxide, butene, sec-butanol a me acetone.Heʻuʻuku ka nui o ka hydrolysis o sec-butyl acetate.Ke hiki mai ka ammonolysis i loko o ka waiʻona waiʻona dilute ma ka lumi wela, ua hoʻololi ʻia ka 20% i amide i 120 mau hola.Hoʻopili ia me benzene i mua o ka boron trifluoride e hana i ka sec-butylbenzene.Ke lawe ʻia ka photo-chlorination, hoʻokumu ʻia ka chlorobutyl acetate.Ma waena o lākou, ʻo 1-methyl-2 chloropropyl acetate ka helu no 66% a me nā isomers ʻē aʻe no 34%.
2.Stability: Paʻa
3. Nā mea i pāpā ʻia:Ikaika oxidants, nā ʻakika ikaika, nā kumu ikaika
4.Polymerization pilikia:ʻAʻole-polymerization
Hoʻohana huahana:
1.Mainly hoʻohana 'ia i loko o ka lacquer solvents, thinners, nā mea kanu aila a me ka resin solvents.Hoʻohana pū ʻia i nā plastics a me nā mea ʻala.ʻAi kūʻē i ka ʻaila.
2.Hoʻohanaʻia e like me nā mea hoʻoheheʻe, nā reagents kemika, hoʻohanaʻia i ka hoʻomākaukauʻana i nā meaʻala
Nā memo mālama huahana:
1. E kūʻai i loko o kahi hale kūʻai ʻoluʻolu.
2. E mālama i ke ahi a me ke kumu wela.
3.ʻAʻole pono eʻoi aku ka mahana o ka mālamaʻana37°C.
4. E hoʻopaʻa i ka pahu.
5. Pono e mālama kaʻawale ʻia mai nā mea oxidizing,nā alkali a me nā waikawa,aole pono e huikau.
6.E hoʻohana i nā kukui pahū-hōʻoia a me nā pono ea.
7. Hoʻopaʻa i ka hoʻohana ʻana i nā mea hana mīkini a me nā mea hana maʻalahi e hoʻohua i nā huna huna.
8.Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia a me nā lako hale kūpono.
