Isingeniso

I-M-trifluoromethylbenzonitrile iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso esiningiliziwe sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:

 

Ikhwalithi:

I-M-trifluoromethylbenzonitrile iyikristale eqinile engenambala ukuya kokuphuzi okuphaphathekile, enephunga eliqinile le-benzene. I-compound iyancibilika kuma-solvents ephilayo njenge-ethanol, i-ether ne-methylene chloride ekamelweni lokushisa.

 

Sebenzisa:

I-M-trifluoromethylbenzonitrile isetshenziswa kakhulu ku-organic synthesis. Ingasetshenziswa futhi ekuhlanganiseni izibulala-zinambuzane namadayi.

 

Indlela:

I-M-trifluoromethylbenzonitrile ingahlanganiswa ngokusabela kwe-cyanide nama-trifluoromethanylation reagents. Indlela evamile ukusebenzisa i-boron cyanide ne-trifluoromethanyl chlorine ukukhiqiza i-m-trifluoromethylbenzonitrile.

 

Ulwazi Lokuphepha:

I-M-trifluoromethylbenzonitrile izinzile uma kuqhathaniswa ngaphansi kwezimo zokusetshenziswa nokugcinwa okuvamile, kodwa kufanele isingathwe ngezinyathelo zokuphepha ezifanele. Ingacasula futhi idle emehlweni nasesikhumbeni futhi kufanele ihlanzwe ngamanzi amaningi ngokushesha ngemva kokuthintana. Izimpahla zokuzivikela ezifanele ezifana nezingubo zamehlo ezivikelayo, amagilavu ​​nezingubo zokuzivikela kufanele zigqokwe ngesikhathi sokusetshenziswa. Gwema ukuhogela umoya nokuwudla. Uma usebenzisa lesi sithako, landela iziqondiso ezifanele zokuphepha futhi uqinisekise ukuthi sisetshenzwa endaweni enomoya omuhle.
