Isingeniso
Imvelo:
1. Kuqinile okucwebezelayo okumhlophe okungaguquguquki ezingeni lokushisa legumbi.
2. Inokunambitheka okubabayo kwe-cyanide futhi incibilika kalula ku-ethanol, i-chloroform, ne-acetonitrile.
Ukusetshenziswa:
1. Kuyinto ebalulekile ye-organic synthesis ephakathi nezinhlelo zokusebenza eziningi emkhakheni wodayi namanye amakhemikhali e-organic.
2. Ingasetshenziselwa ukuhlanganisa izithako ezinjengama-herbicides, odayi, nezivimbelakuvunda zenjoloba.
Indlela:
Indlela yokuhlanganisa ye-2-chlorobenzonitrile ivamise ukutholakala ngokuphendula i-chlorobenzene nge-sodium cyanide. Okokuqala, ngaphansi kwezimo ze-alkaline, i-chlorobenzene ihlangana ne-sodium cyanide yakhe i-chlorophenylcyanide, bese i-hydrolyzed ukuthola i-2-chlorobenzonitrile.
Ukuphepha:
1. Inobuthi obuthile. Ukuthintana noma ukuhogela kungabangela ukucasuka kwamehlo nesikhumba, ngisho nomonakalo.
2. Gqoka izinto zokuzivikela ezifanele ngesikhathi sokuhlinzwa ukuze ugweme ukuthinta isikhumba kanye nomgudu wokuphefumula.
3. Phakathi nenqubo yokusingatha, izinqubo zokusebenza zokuphepha kufanele zilandelwe ukuze kugwenywe izingozi.
