Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali C6H4BrClN2O2. Iyikristale eqinile, emhlophe ukuya kokuphuzi, enephunga elikhethekile.

 

Ukusetshenziswa okuyinhloko kwalesi sakhi kunjengokuhlanganiswa kwamakhemikhali okuphakathi. Ingasetshenziselwa ukuhlanganisa ezinye izinhlanganisela eziphilayo, njengezibulala-zinambuzane, odayi nezidakamizwa. Ingasetshenziswa futhi njenge-ligand ye-organometallic complexes.

Indlela yokulungiselela ye

ingatholakala ngokusabela kwe-bromination kwe-2-chloro-4-methyl-3-nitropyridine. Izinyathelo ezithile zihlanganisa ukuphendula i-2-chloro-4-methyl-3-nitropyridine nge-bromine ngaphansi kwezimo ezifanele zokusabela ukuze kutholwe umkhiqizo oqondiwe.

 

Mayelana nolwazi lokuphepha, inhlanganisela yezinto eziphilayo, kufanele inake ubuthi bayo nokucasuka. Ngesikhathi sokusetshenziswa, ukucaciswa okuhambisanayo kokusebenza kokuhlola kufanele kubhekwe, futhi ukuthintana nesikhumba namehlo kufanele kugwenywe. Izinto zokuzivikela ezinjengamagilavu ​​nezibuko kufanele zigqokwe njengoba kudingeka. Ngesikhathi esifanayo, inhlanganisela kufanele igcinwe kahle futhi isingathwe ukuze kugwenywe ukuxubana namanye amakhemikhali ukuvimbela izingozi.
