Trifluoroacetylacetone CAS:367-57-7

Trifluoroacetylacetylactone (TFAA) bụ ngwakọta dị iche iche nwere ihe pụrụ iche kemịkalụ nke na-enye aka na uru ya sara mbara n'ọtụtụ ngwa ụlọ ọrụ mmepụta ihe dị iche iche. Njirimara TFAA bụ ihe e ji mara ya site na nhazi molekul ya, nke gụnyere otu trifluoromethyl (-CF3) nke ejikọtara na usoro diketone. Nhazi a na-enye nkwụsi ike na mmeghachi omume pụtara ìhè na ihe mejupụtara ahụ, na-eme ka ọ dabara adaba maka mmeghachi omume kemịkalụ dị iche iche na ngwa. TFAA na-adịkarị dị ka mmiri kwụsiri ike, enweghị agba nwere ebe esi mmiri nke ihe dị ka 120°C ma na-egosipụta mgbaze dị oke mma na ihe mgbaze polar dị ka acetone na ethanol. Nkwụsi ike ya n'okpuru ọtụtụ ọnọdụ na-enye ohere maka ojiji ya na nyocha agụmakwụkwọ na ntọala ụlọ ọrụ mmepụta ihe. Ojiji Njiko Organic: TFAA na-eje ozi dị ka ihe dị mkpa na njikọ organic, karịsịa na ntinye nke otu trifluoromethyl n'ime molekul organic. Ike a dị oke mkpa maka ịmepụta ọgwụ, agrochemicals, na kemịkalụ pụrụ iche nwere ọrụ bayoloji ka mma na nkwụsi ike kemịkalụ. Njiko Kemistri Nhazi: Na kemistri nhazi, TFAA na-arụ ọrụ dị ka ligand n'ihi ọnụnọ nke otu carbonyl na trifluoromethyl, na-emepụta mgbagwoju anya kwụsiri ike na ion ígwè. Ihe mgbagwoju anya ndị a na-achọta ngwa na ihe mkpali, ihe mmetụta molekul, na dịka ihe etiti na mmepụta nke usoro metal-organic (MOFs). Catalysis: A na-eji TFAA eme ihe dị ka ihe mkpali na mgbanwe organic dị iche iche, gụnyere aldol condensations, mgbakwunye nucleophilic, na mmeghachi omume Michael. Ike ya ime ka ọnụego mmeghachi omume na nhọrọ dịkwuo mma na-eme ka ọ baa uru na ụlọ ọrụ ọgwụ na kemịkalụ dị mma. A na-emepụta Trifluoroacetylacetone site na mmeghachi omume nke trifluoroacetic acid na acetylacetone n'okpuru ọnọdụ a na-achịkwa. Usoro esterification na-eme ka TFAA dị ka mmiri mmiri kwụsiri ike, nke na-enweghị agba, nke enwere ike ịsacha site na distillation ma ọ bụ mwepụta ihe mgbaze iji nweta ịdị ọcha dị elu dabara adaba maka ngwa ụlọ ọrụ mmepụta ihe. Ụzọ njikọ dị mfe na nnweta nke ihe ndị e ji eme ihe na-enye aka na ọnụ ahịa ya na ojiji ya sara mbara na nyocha agụmakwụkwọ na usoro ụlọ ọrụ mmepụta ihe. Na nchịkọta, trifluoroacetylacetone bụ ihe mejupụtara ọtụtụ ihe nwere ngwa dị mkpa na njikọ organic, kemistri nhazi, na catalysis. Njirimara kemịkalụ pụrụ iche ya, gụnyere nkwụsi ike na mmeghachi omume, na-eme ka ojiji ya dị ka ihe owuwu dị mkpa n'ịmepụta ihe ndị dị elu, ọgwụ, na kemịkalụ pụrụ iche, na-akwado ọganihu n'ọtụtụ ngalaba ụlọ ọrụ na nyocha sayensị dị iche iche.
