Intangiriro
Trifluoromethylation ni imiti kama ya chimique aho amatsinda ya trifluoromethyl ashobora kwinjizwa muri molekile kama hakoreshejwe tegafluor reagent nka TMSCF3.
Ibyiza bya tegafluor:
- Tegafluor nigikorwa cyingenzi cyo guhindura itsinda, rishobora kwinjiza amatsinda ya trifluoromethyl hamwe nubucucike bwa electron kugirango uhindure imiterere yumubiri na chimique ya molekile.
- Amatsinda ya Trifluoromethyl afite imbaraga za elegitoronike zikomeye, zishobora kongera amashanyarazi ya molekile hamwe no gukomera kwa solve.
- Ibicuruzwa bya tegafluor reaction muri rusange bihagaze neza mubinyabuzima kandi bikora mubuzima.
Imikoreshereze ya tegafluor:
- Mu rwego rwibikoresho siyanse, tegafluor irashobora guhindura imiterere yibikoresho, ikongerera umutekano hamwe nikirere.
Uburyo bwo gutegura tegafluor:
- Byakunze gukoreshwa tegafluor reagents zirimo: TMSCF3, Ruppert-Prakash reagent, nibindi.
- Tegafluor reaction ikorwa muburyo bwikirere, hifashishijwe umusemburo wa inert (urugero, methylene chloride, chloroform) nkuburyo bwo kubyitwaramo.
- Imiterere yimyitwarire isanzwe isaba ubushyuhe bwo hejuru hamwe nigihe kinini cyo kubyitwaramo, kandi akenshi bisaba kongeramo catalizator (urugero, cataliste yumuringa).
Amakuru yumutekano kuri tegafur:
- Tegafluor reagents ni uburozi kandi burashobora kwangirika, kandi hagomba gufatwa ingamba zikwiye mugihe ukemura.
- Imyuka (urugero: hydrogène fluoride) ikorwa mugihe cya reaction nayo iteje akaga kandi igomba gukoreshwa mubihe bihumeka neza.
- Hagomba kwitonderwa kugirango wirinde guhura n’amazi cyangwa ubuhehere mugihe cyo gukora kugirango wirinde imiti idasubirwaho.
- Ibicuruzwa nibicuruzwa mugihe cya tegafluor reaction bisaba gufata neza no guta imyanda.
