Intshayelelo

I-M-trifluoromethylbenzonitrile yikhompawundi ephilayo. Oku kulandelayo yintshayelelo eneenkcukacha kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:

 

Umgangatho:

I-M-trifluoromethylbenzonitrile yikristale engenambala ukuya kumthubi, enevumba elinamandla lebenzene. Ikhompawundi inyibilika kwii-solvents eziphilayo ezifana ne-ethanol, i-ether kunye ne-methylene chloride kwiqondo lokushisa.

 

Sebenzisa:

I-M-trifluoromethylbenzonitrile isetyenziswa ngokubanzi kwi-organic synthesis. Inokusetyenziswa kwakhona kwi-synthesis ye-pesticides kunye nedayi.

 

Indlela:

I-M-trifluoromethylbenzonitrile inokwenziwa ngokusabela kwe-cyanide kunye ne-trifluoromethanylation reagents. Indlela eqhelekileyo kukusebenzisa i-boron cyanide kunye ne-trifluoromethanyl chlorine ukuvelisa i-m-trifluoromethylbenzonitrile.

 

Ulwazi ngoKhuseleko:

I-M-trifluoromethylbenzonitrile izinzile phantsi kokusetyenziswa okuqhelekileyo kunye neemeko zokugcina, kodwa kufuneka ziphathwe ngokufanelekileyo. Inokucaphukisa kwaye idle emehlweni kunye nolusu kwaye kufuneka ihlanjululwe ngamanzi amaninzi ngokukhawuleza emva kokudibanisa. Izixhobo ezifanelekileyo zokuzikhusela ezifana nempahla yamehlo ekhuselayo, iiglavu kunye nempahla yokukhusela kufuneka zinxitywe ngexesha lokusetyenziswa. Kuphephe ukuphefumla kunye nokungeniswa. Xa usebenzisa le khompawundi, landela izikhokelo zokhuseleko ezifanelekileyo kwaye uqinisekise ukuba isetyenziswa kwindawo engena umoya.
