Guryaha Alaabta:
1.La mid ah butyl acetate.Waxay u jajabisaa 1-butene, 2-butene, ethylene iyo propylene marka la kululeeyo ilaa 500 ° C.Marka sek-butyl acetate la dhex mariyo dhogor galaas ah oo ku jira qulqulka nitrogen ee 460 ilaa 473 ° C, 56% 1-butene, 43% 2-butene iyo 1% propylene ayaa la soo saaraa.Marka la kululeeyo ilaa 380 ° C iyada oo ay jirto thorium oxide, waxay u jajabisaa hydrogen, carbon dioxide, butene, sec-butanol iyo acetone.Heerka hydrolysis of sec-butyl acetate waa yar yahay.Marka ammonolysis ay ku dhacdo dareeraha alkoholka ah ee heerkulka qolka, 20% ayaa loo beddelaa amide 120 saacadood.Waxay la falgashaa benzene iyadoo ay jirto boron trifluoride si ay u sameyso sec-butylbenzene.Marka sawirka-chlorination la sameeyo, chlorobutyl acetate ayaa la sameeyaa.Waxaa ka mid ah, 1-methyl-2 chloropropyl acetate ayaa xisaabiya 66% iyo isomers kale ayaa xisaabiya 34%.
2. Xasilooni: Xasilooni
3.Waxyaabaha mamnuuca ah:Xoog oxiqoob-ka-ciyaarka, acids xooggan, saldhigyo xooggan
4. Khatarta polymerisation:Aan ahayn polymerisation
Codsiga Alaabta:
1.Mainly loo isticmaalo dareerayaasha lacquer, khafiifiyayaal, saliidaha khudradda kala duwan iyo dareerayaasha resin.Waxa kale oo loo isticmaalaa bacaha iyo wax soo saarka xawaashka.Beesalka ka hortagga garaaca.
2.Used sida dareerayaasha, reagents kiimikaad, loo isticmaalo diyaarinta dhir udgoon
Qoraalada Kaydinta Alaabta:
1. Ku kaydi bakhaar qabow oo hawo leh.
2. Ka fogow dabka iyo isha kulaylka.
3. Heerkulka kaydinta waa inuusan dhaafin37°C.
4.Ka ilaali weelka oo xiran.
5. Waa in si gooni ah loo kaydiyaa walxaha oksida,alkalis iyo acids,waana inaan marnaba la isku darin.
6.Isticmaal nalalka aan qarxin iyo tas-hiilaadka hawo-siinta.
7. Mamnuuci isticmaalka qalabka farsamada iyo qalabka si fudud loo dhalin karo.
8.Aagga kaydinta waa in lagu qalabeeyaa qalabka daaweynta degdega ah ee daadsan iyo agab hoy oo ku habboon.
