Intshayelelo
4,4'-Dimethylbenzophenone. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-4,4′-dimethylbenzophenone:
Umgangatho:
I-4,4′-I-Dimethylbenzophenone yinto eqinileyo yekristale engenambala enganyibiliki kakuhle emanzini kwindawo yobushushu begumbi, kodwa i-soluble kwii-solvents eziphilayo ezifana ne-alcohols kunye ne-esters.
Ukusetyenziswa: Isenokusetyenziswa njengendawo ephakathi kwi-organic synthesis yokwenziwa kwezinye iikhompawundi.
Indlela:
Indlela yokulungiselela esetyenziswa ngokuqhelekileyo ilungiselelwe ngokusabela kwe-benzophenone kunye ne-n-butylformaldehyde phantsi kweemeko ze-alkali. Amanyathelo athile okudibanisa angabandakanya isizukulwana se-diazonium salts ye-ketones okanye i-oxime, eyancipha ibe yi-4,4'-dimethylbenzophenone.
Ulwazi ngoKhuseleko:
Iprofayili yokhuseleko lwe-4,4′-dimethylbenzophenone iphezulu, kodwa oku kulandelayo kufuneka kuqatshelwe:
- Isenokucaphukisa amehlo kunye nolusu, ngoko thatha amanyathelo okhuseleko xa uyisebenzisa.
- Kuphephe ukuphefumla uthuli okanye ukuchukumisa isisombululo salo ukuphepha ukungonwabi okanye ukusabela ngokwanelisayo.
- Kuphephe ukudibana namadangatye avulekileyo ngexesha lokusetyenziswa, kwaye ugcine kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu.
- Ukusetyenziswa phantsi kwesikhokelo sobuchule kwaye ulandele iindlela ezifanelekileyo zokhuseleko.
