Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C7H3BrFN. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-crystalline engenambala eqinile.
-Indawo yokuncibilika: cishe ku-59-61°C.
Iphuzu elibilayo: mayelana ne-132-133 ℃.
-Umkhawulo wephunga: Ayikho idatha ethembekile.
-Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo ezifana ne-ether, i-dimethylformamide ne-benzene, ezingancibiliki emanzini.
Sebenzisa:
-i-organic synthesis intermediate engasetshenziswa ukwenza izinhlanganisela ezifana nezidakamizwa, izibulala-zinambuzane kanye nodayi.
-Ingasetshenziswa njenge-reagent yokwethula i-halogen kumakhompiyutha anephunga elimnandi ku-organic synthesis.
Indlela Yokulungiselela:
-i-fluorobenzonitrile ingalungiswa ngokungeza i-cuprous bromide (CuBr) ku-4-fluorobenzonitrile (C7H4FN).
Ulwazi Lokuphepha:
-Kungase kucasule futhi kudle, futhi ukuthintana nesikhumba namehlo kungase kubangele ukucasuka.
-Gqoka izinto zokuzivikela ezifanele njengezibuko, amagilavu, namajazi elebhu ngesikhathi sokusebenza.
-Uma usebenzisa futhi ugcina, kuyadingeka ukuhambisana nezinqubo zokusebenza eziphephile futhi ugcine kahle esitsheni esivaliwe, kude nama-ignition agents kanye nama-oxidizing.
-Uma uhogelwe noma udliwe, funa usizo lwezempilo ngokushesha. Uma kwenzeka ukuthintana, shayela ngokushesha indawo ethintekile ngamanzi amaningi futhi ufune usizo lwezokwelapha.
