Izinga eliphezulu lokuhlanzeka kwe-1,1,3-trichloroacetone yokulungiselela

Abstract:i-acetone catalyzed chloride futhi ikhiqizwe yi-solvent crystallization ku-1,1,3-trichloroacetone enobumsulwa obuphakeme obungekho ngaphansi kuka-99.0%, ngesivuno esingu-45%o Amagama angukhiye:1,1,3-trichloroacetone;ukuhlanganiswa; ubumsulwa obukhulu

----------.Isandulelo

1,1,3■i-trichloroacetone iyingxenye ebalulekile emaphakathi ekukhiqizweni kwe-folic acid.Okwamanje,1,1,3.i-acetone trihloropacetone,umjikelezo omude wokukhiqiza(amahora angama-48),ukukhetha okubi,isivuno esiphansi,1,1,3- okuqukethwe kwe-trichloropacetone cishe ku-17% kuphela, ngemva kokukhipha amanzi, okuqukethwe kwawo kuphela ku-51.9%.Futhi izindleko zokukhiqiza ziphezulu, ukulungiswa komkhiqizo kuphansi.Lokhu konke kuholela ezindlekweni eziphezulu zokukhiqiza i-folic acid yasekhaya, kunzima ukuthuthukisa okuqukethwe nokunye. izinkinga.Umbhali ufunde inqwaba yemibhalo yasekhaya neyangaphandle.Ngemuva kokuhlolwa okuningi nezifundo, sengeze i-catalyst kanye nesivinini sokulawula i-fou chlorine, sehlisa isikhathi sokusabela sibe yi-1,1,3-3 trichlorropacetone emahoreni angama-24, kanye ne-1,1,3-3 ye-trichloropacetone crystallization ngobumsulwa obungaphezu kuka-99% futhi isivuno esingaphezu kuka-45%.

1. Izinyathelo zokuhlola

Eflaskini enentamo emine ene-500ml eyindilinga eyindilinga, inani elithile le-acetone kanye ne-catalyst lanyakaziswa futhi lafakwa ku-chlorine ekushiseni okusabela okungu-10~30 W.Qala isikhathi, yeka ukudlula ku-chlorine amahora ambalwa ngemva kokusabela, futhi uqhubeke. ukugqugquzela ihora elingu-1. I-solvent ekhethekile efana nempahla yengezwe engxubeni ewumphumela, ivuselelwe ihora le-1 ngenkathi ipholile ku-10 ° C crystallization, ikhipha i-1,1,3-trichloroacetone.

1. 1,1,3.Ukunqunywa okukhethiwe kokuhlanzeka kwe-trichloroacetone

I-Varin 3700 gas chromatograph,QF・1 ikholomu yokugcwalisa kanye nomtshina we-FID zisetshenziswe ukuze kukhethwe ngokukhethekile inzuzo yokuhlanzeka komkhiqizo nesixazululo se-chloride.

1. Imiphumela yengxoxo
2. Umthelela we-catalyst ekukhetheni kwe-chloride ubonise ukukhetha kwe-acetone chlorination

Ithonya elikhulu,Ithebula 1 libala isethi yemiphumela yokuhlolwa.Kuthebula 1, ukukhetha okuncane kwe-1,1,3-trichloroacetone kukhuphuke kakhulu (cishe 19.1%) ngaphandle kwe-catalyst, futhi

　　I-compound amine catalyst ihamba phambili, ifika ku-57.5%o.Izimo zokuhlola: Innl acetone, 3nr) l chlorine, i-catalyst 0.6g, izinga lokushisa 1030°C,

1. Umthelela wesivinini se- through-chlorine ekuphenduleni

Ukuhlola kutholwe ukuthi i-chlorine efanayo inokungakhethi kahle komkhiqizo, okuthuthukisa kakhulu ukukhetha komkhiqizo kanye nesivuno.
