Intshayelelo
I-2,6-Difluorobenzonitrile, eyaziwa ngokuba yi-2,6-difluorobenzonitrile, i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 2,6-Difluorobenzonitrile lulwelo engenambala okanye crystal emhlophe.
- Ukunyibilika: Ukunyibilika kwizinyibilikisi eziphilayo.
Sebenzisa:
- I-2,6-Difluorobenzonitrile idla ngokusetyenziswa njengento ebalulekileyo ephakathi kwi-organic synthesis, umzekelo njengento yokuqala yokwenziwa kwezinye izinto eziphilayo.
Indlela:
- Indlela yokulungiselela i-2,6-difluorobenzonitrile ifumaneka ikakhulu ngokusabela kwe-2,6-difluorobenzyl yotywala kunye ne-sodium cyanide phambi kwe-alkaline catalyst.
- Amanyathelo athile abandakanya ukusabela kwe-2,6-difluorobenzyl yotywala kunye ne-sodium cyanide phantsi kweemeko ze-alkali, ilandelwa yi-acidification ukufumana imveliso ye-2,6-difluorobenzonitrile.
Ulwazi ngoKhuseleko:
- I-2,6-difluorobenzonitrile ine-toxicity ephantsi, kodwa kufuneka kuthathelwe ingqalelo ukuphepha ukudibanisa ngokuthe ngqo nolusu, amehlo kunye nokuphefumula.
- Iinkqubo ezifanelekileyo zokhuseleko kunye nezixhobo ezifanelekileyo zokukhusela kufuneka zilandelwe xa zisetyenziswa okanye zigcinwe.
- Xa i-compound ibanjwe ngengozi okanye ifakwe umoya, kufuneka icocwe okanye ifakwe umoya ngokukhawuleza kwaye unyango kufuneka lufunwe ngokukhawuleza.
