Guryaha Alaabta:
1. Tartiib tartiib tartiib tartiib ah oo biyo ah oo ay joogaan si loo soo saaro acetic acid iyo propanol.Xawaaraha hydrolysis waa 1/4 ee ethyl acetate. Marka propyl acetate lagu kululeeyo 450 ~ 470 ℃, marka lagu daro abuurista propylene iyo acetic acid, waxaa jira acetaldehyde, propionaldehyde, methanol, ethanol, ethane, ethylene iyo biyo.Joogitaanka nikkel, kuleyl ilaa 375 ~ 425 ℃, jiilka carbon monoxide, carbon dioxide, hydrogen, methane iyo ethane.Chlorine, bromine, hydrogen bromide iyo propyl acetate waxay ka falceliyaan heerkul hooseeya.Marka lagu falceliyo koloriin iftiinka hoostiisa, 85% monochlororopyl acetate ayaa la soo saaraa 2 saacadood gudahood.Tan, 2/3 ka mid ah waa 2-chloro beddelka iyo 1/3 waa beddelka 3-chloro.Joogitaanka aluminium trichloride, propyl acetate waxaa lagu kululeeyaa benzene si loo sameeyo propylbenzene, 4-propylacetophenone iyo isopropylbenzene.
2. Xasilooni: Xasilooni
3.Waxyaabaha mamnuuca ah: oksaydhiyeyaasha xooggan, acids, saldhigyada
4.Polymerisation khatar: non-polymerisation
Codsiga Alaabta:
1.Alaabadani waa wakiilka qalajinta si tartiib ah oo degdeg ah oo loogu talagalay khadadka flexographic iyo gravure, gaar ahaan daabacaadda filimada olefin iyo polyamide.Waxa kale oo loo isticmaalaa dareere ahaan nitrocellulose;caag koloriin leh iyo balaastikada phenolic-ku-dhal-celiyaha.Propyl acetate waxay leedahay udgoon yar oo miro leh.Marka la qaso, waxay leedahay caraf udgoon u eg pear.Alaabooyinka dabiiciga ah ayaa ku jira muuska;yaanyada;baradhada isku dhafan iyo wixii la mid ah.Xeerarka GB2760-86 ee Shiinaha ee isticmaalka la oggol yahay ee xawaashka la cuni karo.Inta badan loo isticmaalo diyaarinta pear iyo currant iyo noocyada kale ee dhadhanka, sidoo kale loo isticmaalo sida dareere udgoon ku salaysan miro.Tiro badan oo ah walxo dabiici ah iyo walxo aan dabiici ahayn oo loo isticmaalo sida dareeraha soo saarista, rinjiga, rinjiga buufinta nitro, varnish iyo resins kala duwan iyo dareerayaasha iyo soo saarista xawaashka.
2. Loo isticmaalo soo saarista xawaashka la cuni karo.Sidoo kale loo isticmaalo sida nitrocellulose, caag koloriin leh iyo kulaylka mugga caagga ah ee phenolic, iyo sidoo kale rinjiga, balaastiga, isku-dhafka organic.
3.Used sida wakiilka dhadhanka, xawaashka la cuni karo, dareeraha nitrocellulose iyo reagent, iyo sidoo kale loo isticmaalo wax soo saarka ee lacquer, balaastikada, synthesis organic iyo wixii la mid ah.
Qoraalada Kaydinta Alaabta:
