Intshayelelo
I-3,4 '-Dichloropropiophenone, i-chemical formula C9H7Cl2O, i-organic compound.
Indalo:
I-3,4 '-I-Dichloropropiophenone yinto eqinileyo engenambala ukuya kumthubi kunye nevumba lekhemikhali elahlukileyo. Ayinyibiliki emanzini kwaye inyibilika kancinane kwiziselo ezinxilisayo kunye ne-ethers.
Sebenzisa:
I-3,4 '-I-Dichloropropiophenone idla ngokusetyenziswa njenge-reagent kwi-organic synthesis. Ingasetyenziselwa ukuhlanganiswa kweziyobisi, idayi kunye nezinye iikhompawundi. Isenokusetyenziswa njengemathiriyeli ekrwada ukulungiselela amayeza okubulala izitshabalalisi kunye neencasa.
Indlela yokulungiselela:
Kukho iindlela ezahlukeneyo zokulungiselela i-3,4 '-Dichloropropiophenone. Indlela eqhelekileyo kukufumana i-3,4'-dichlorophenyl ethanone nge-bromination okanye i-chlorination phantsi kweemeko ze-alkaline.
Ulwazi ngoKhuseleko:
I-3,4 '-I-Dichloropropiophenone yinto enetyhefu kunye nokudibanisa ngokuthe ngqo kwesikhumba kunye nokuphefumla imiphunga yayo kufuneka kugwenywe. Izixhobo ezifanelekileyo zokuzikhusela, ezinjengeeglavu zokuzikhusela ngemichiza kunye nokukhusela amehlo, zifanele zinxitywe xa usetyenziswa okanye uphathwa. Gwema ukushisa okuphezulu kunye nomlilo ovulekileyo ngexesha lokugcina. Qiniseka ukuba uyisebenzisa kwindawo ekhuselekileyo nengena umoya kwaye uyilahle kwisikhongozelo esingenabungozi. Ukuba ukungeniswa okanye ukudibana kwenzeka, funa uncedo lwezonyango ngokukhawuleza.
