Okwu mmalite
Trifluoromethylation bụ mmeghachi omume kemịkalụ organic nke enwere ike iwebata otu trifluoromethyl n'ime ụmụ irighiri ihe site na iji tegafluor reagents dị ka TMSCF3.
Njirimara nke tegafluor:
- Tegafluor bụ mmeghachi omume ntughari otu dị mkpa, nke nwere ike iwebata otu trifluoromethyl nwere ụfọdụ njupụta elektrọn iji gbanwee njirimara anụ ahụ na kemịkalụ nke ụmụ irighiri ihe.
- Ndị otu Trifluoromethyl nwere mmasị elektrọn siri ike, nke nwere ike ịbawanye electrophilicity nke molekul na solubility nke ihe mgbaze.
- Ngwaahịa nke mmeghachi omume tegafluor bụ n'ozuzu kemịkalụ kwụsiri ike ma na-arụ ọrụ nke ndụ.
Ojiji tegafluor:
- N'ihe gbasara sayensị ihe, tegafluor nwere ike ịgbanwe ọdịdị elu nke ihe, mee ka nkwụsi ike ha na iguzogide ihu igwe.
Usoro nkwadebe nke tegafluor:
- reagents tegafluor a na-ejikarị gụnyere: TMSCF3, Ruppert-Prakash reagent, wdg.
A na-eme mmeghachi omume Tegafluor na ikuku inert, na-eji ihe mgbaze inert (dịka ọmụmaatụ, methylene chloride, chloroform) dị ka usoro mmeghachi omume.
- Ọnọdụ mmeghachi omume na-achọkarị okpomọkụ mmeghachi omume dị elu yana ogologo oge mmeghachi omume, ma na-achọkarị mgbakwunye nke ihe mkpali (dịka ọmụmaatụ, ọla kọpa).
Ozi nchekwa na tegafur:
- Tegafluor reagents bụ ihe na-egbu egbu ma na-emebi emebi, ọ dị mkpa ka kpachara anya kwesịrị ekwesị mgbe a na-ejikwa ya.
- Gases (dịka ọmụmaatụ hydrogen fluoride) emepụtara n'oge mmeghachi omume dịkwa ize ndụ ma ọ dị mkpa ka ejiri ya rụọ ọrụ n'okpuru ọnọdụ ikuku.
- Ekwesịrị ịkpachapụ anya ka ịzere kọntaktị na mmiri ma ọ bụ iru mmiri n'oge a na-arụ ọrụ iji zere mmeghachi omume kemịkal na-enweghị ike ịgbanwe.
- Reactants na ngwaahịa n'okpuru ọnọdụ mmeghachi omume tegafluor chọrọ ọgwụgwọ kwesịrị ekwesị na mkpofu mkpofu.
