2-Cyano-5-fluorobenzotrifluoride (CAS# 194853-86-6) Intshayelelo
I-4-fluoro-2-(trifluoromethyl) i-benzonitrile yikristale engenambala okanye eqinileyo enevumba elimnandi elinuka kamnandi. Inozinzo oluhle kunye nokuzinza kwe-thermal kwiqondo lokushisa, kwaye ayinyibiliki emanzini, kodwa i-soluble kwi-solvents ezininzi eziphilayo.
Sebenzisa:
I-4-fluoro-2- (trifluoromethyl) i-benzonitril yinto ebalulekileyo ye-organic intermediate enokuthi idlale indima ebalulekileyo ekuhlanganiseni iziyobisi, i-pesticides kunye neekhemikhali ezikhethekileyo. Ingasetyenziswa ekudityanisweni kweziyobisi, imichiza yokungunda, i-antioxidants kunye nezinye iikhompawundi, kodwa ingasetyenziswa njengedayi kunye nezixhobo zokuthambisa.
Indlela:
Indlela eqhelekileyo yokulungiselela i-4-fluoro-2- (trifluoromethyl) i-benzonitrile ifumaneka ngokuphendula kwe-fluorination kunye ne-cynation reaction. Enye indlela eqhelekileyo kukusabela i-2,4-difluoro-1-chlorobenzene kunye ne-trifluoronitrile ukunika imveliso.
Ulwazi ngoKhuseleko:
Nxiba iiglavu zokukhusela iikhemikhali, izibuko kunye nempahla yokukhusela xa uphethe i-4-fluoro-2- (trifluoromethyl) benzonitril. Kuphephe ukudibana nesikhumba kunye nokuphefumla umphunga. Kwimeko yoqhagamshelwano ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango. Xa igcinwe, kufuneka ibekwe kwindawo eyomileyo, epholileyo, engenamoya, kude nomlilo kunye ne-oxidant. Landela iinkqubo ezifanelekileyo zokhuseleko kunye nezikhokelo.
