Intshayelelo
I-M-fluorobenzonitrile, eyaziwa ngokuba yi-2-fluorobenzonitrile, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-m-fluorobenzonitrile:
Umgangatho:
- Imbonakalo: M-fluorobenzonitrile lulwelo engenambala okanye crystalline okuqinileyo.
- Ukunyibilika: Inyibilika kwizinyibilikisi ezininzi ze-organic ezifana ne-ethanol, i-chloroform, njl.
- Ubutyhefu: I-M-fluorobenzonitrile inetyhefu ethile emzimbeni womntu kwaye kufuneka iphathwe kwaye isetyenziswe ngononophelo.
Sebenzisa:
- Abaphakathi: I-M-fluorobenzonitrile yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye ingasetyenziselwa ukudibanisa ezinye izinto eziphilayo.
- Isibulali-zinambuzane: Isenokusetyenziswa njengemathiriyeli ekrwada kwizitshabalalisi.
Indlela:
I-M-fluorobenzonitrile ingalungiswa ngokusabela kwe-fluorochlorobenzene kunye ne-sodium cyanide phantsi kweemeko ze-alkaline.
Ulwazi ngoKhuseleko:
- Ukucaphuka kwesikhumba kunye neliso: I-M-fluorobenzonitrile inokubangela ukucaphuka kwesikhumba kunye namehlo, kwaye ukudibana nolusu kunye namehlo kufuneka kuphetshwe xa uyisebenzisa.
- Umngcipheko wokuphefumla: Ukuphefumla umphunga we-m-fluorobenzonitrile kunokubangela ukucaphuka kokuphefumula, ngoko qinisekisa ukuba usetyenziswa kwindawo engena umoya.
- Ukugcinwa kunye nokuphatha: I-M-fluorobenzonitrile kufuneka igcinwe kwisitya esingenawo umoya, kude nomlilo kunye namaqondo okushisa aphezulu, kwaye ugweme ukudibanisa ne-oxidants kunye ne-acids. Izixhobo zokukhusela zomntu ezifana neeglavu, iiglavu, njl.njl. kufuneka zinxitywe ngexesha lokuphatha.
