Okwu mmalite
ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE (ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE) bụ ngwakọta organic. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
-ọdịdị: Ọ na-abụkarị mmiri mmiri na-enweghị agba ma ọ bụ mmiri na-acha odo odo.
-Solubility: Enwere ike ịgbaze ya na ihe mgbaze organic, dị ka ethanol, ether na dichloromethane.
- Ebe mgbaze na ebe esi mmiri: Ebe mgbaze ya dị ihe dịka -8°C, ebe isi ya dịkwa ihe dịka 108-110°C.
Jiri:
-reagent na Advanced Organic Synthesis: ETHYL 4,4, 4-trifluororo-2-butynoate nwere ike iji dị ka ihe dị mkpa reagent na organic njikọ. Ọ nwere ike itinye aka na mmeghachi omume dị iche iche nke organic, dị ka acylation, condensation na cyclization mmeghachi omume, nke a na-eji mee ihe dị iche iche nke ogige organic.
- Ihe kemịkalụ: Enwere ike iji ya maka mmeghachi omume ụfọdụ na kemịkalụ polymer, dị ka ndị na-emekọrịta ihe maka polymer synthetic.
Usoro:
Enwere ike ịkwadebe ETYL 4,4,4-TRIFLUORO-2-BUTYNOATE site na usoro ndị a:
1. Nke mbụ, butynol (2-butynol) na-emeghachi omume na anhydrous hydrogen fluoride iji mepụta butynyl fluoride.
2. Mgbe ahụ, butynyl fluoride na-emeghachi omume na ETHYL chloroacetate iji mepụta ETYL 4,4, 4-trifluororo-2-butynoate.
Ozi nchekwa:
- ETYL 4,4,4-TRIFLUORO-2-BUTYNOATE kwesịrị izere ikpughe ikuku ogologo oge n'ihi na ọ na-enwe mmetụta maka mmiri na mmiri.
