Intshayelelo
I-AFBX yikristale engenambala eqinileyo. Indawo yayo yokunyibilika imalunga nama-260-261 degrees Celsius. Izinzile kwiqondo lokushisa lokushisa kwaye inokuchithwa kwii-solvents eziqhelekileyo.
Sebenzisa:
I-AFBX isetyenziswa ikakhulu njengendawo ephakathi kwizitshabalalisi kunye nemichiza yokutshabalalisa ukhula. Inomsebenzi olungileyo wokutshabalalisa izinambuzane kunye nokutshabalalisa ukhula kwaye inokusetyenziswa ngokuchasene neentlobo ezahlukeneyo zezinambuzane kunye nokhula. Ukongeza, inokusetyenziswa kwakhona njengomlawuli wokukhula kwezityalo kwintsimi yezolimo.
Indlela:
I-synthesis ye-AFBX inokufumaneka ngokuphendula kwe-2,2-difluoro -1,3-benzobisoxazole kunye ne-ammonia. Ukusabela ngokuqhelekileyo kuqhutyelwa kwiqondo lokushisa eliphezulu, kwaye inkqubo yokusabela ingakhuselwa yi-nitrogen okanye enye igesi engasebenzi. Iindlela ezikhethekileyo zokwenziwa kwakhona zibandakanya uchungechunge lwamanyathelo ekhemikhali, kubandakanywa nokukhethwa kweemeko zokusabela kunye ne-catalysts.
Ulwazi ngoKhuseleko:
I-AFBX ikhuselekile phantsi kweemeko ezichanekileyo zokusetyenziswa kunye nokugcinwa. Nangona kunjalo, yikhemikhali, ngoko ke kufuneka ihambelane nezinye iinkqubo zokhuseleko. Izixhobo ezifanelekileyo zokukhusela ezifana neeglavu zelebhu, iiglavu kunye neengubo zelebhu kufuneka zisetyenziswe xa uphatha kwaye ubamba i-AFBX. Kuphephe ukudibana nolusu, amehlo kunye nomgudu wokuphefumla. Ukuba kukho ukudibanisa, hlambulula ngamanzi ngokukhawuleza. Ngelo xesha, ukusetyenziswa kunye nokuchithwa kwe-AFBX kufuneka kuhambelane nemimiselo kunye nezikhokelo zendawo.
