Intshayelelo
Indalo:
1. Yikristale emhlophe eqinileyo engaguquguqukiyo kwiqondo lobushushu begumbi.
2. Inencasa yecyanide ebabayo kwaye inyibilika lula kwi-ethanol, i-chloroform, kunye ne-acetonitrile.
Ukusetyenziswa:
1. Yinto ebalulekileyo ye-organic synthesis intermediate kunye nezicelo ezibanzi kwiinkalo zedayi kunye nezinye iikhemikhali eziphilayo.
2. Ingasetyenziselwa ukwenza iikhompawundi ezifana nemichiza yokutshabalalisa ukhula, idayi, kunye nezithinteli zerabha.
Indlela:
Indlela ye-synthesis ye-2-chlorobenzonitrile idla ngokufunyanwa ngokuphendula i-chlorobenzene nge-sodium cyanide. Okokuqala, phantsi kweemeko ze-alkaline, i-chlorobenzene iphendula kunye ne-sodium cyanide ukwenza i-chlorophenylcyanide, ethi emva koko i-hydrolyzed ukufumana i-2-chlorobenzonitrile.
Ukhuseleko:
1. Inetyhefu ethile. Ukuqhagamshelana okanye ukuphefumla kunokubangela ukucaphuka kwamehlo kunye nolusu, kunye nomonakalo.
2. Nxiba izixhobo ezifanelekileyo zokuzikhusela ngexesha lomsebenzi ukuthintela ukudibana nolusu kunye nomgudu wokuphefumla.
3. Ngethuba lenkqubo yokusingatha, iinkqubo zokusebenza zokhuseleko kufuneka zilandelwe ukuphepha izingozi.
