Intshayelelo
I-4-Biacetophenone yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-4-biacetophenone:
Umgangatho:
- Imbonakalo: 4-Biacetophenone lulwelo olungenambala ukuya ekukhanyeni emthubi.
- Ukungcamla: Ivumba.
- Ukunyibilika: akunyibiliki emanzini, kunyibilika kwizinyibilikisi eziphilayo ezifana notywala, iether, njl.
Sebenzisa:
- I-4-Biphenyacetophenone yinto ebalulekileyo ephakathi kwi-organic synthesis, enokuthi isetyenziswe ukudibanisa iintlobo ezahlukeneyo zezinto eziphilayo, ezifana ne-triphenylamine, i-diphenylacetophenone, njl.
Indlela:
I-4-Biacetophenone inokulungiswa nge-acylation reaction, kwaye indlela eqhelekileyo kukusabela i-acetophenone nge-anhydride, eyenziwa phantsi kweemeko ze-acidic.
Ulwazi ngoKhuseleko:
- 4-Biphenyacetophenone inetyhefu ephantsi phantsi kweemeko eziqhelekileyo zokusetyenziswa. Njengazo zonke iikhemikhali, amanyathelo afanelekileyo okhuseleko kufuneka athathwe xa uphathwa.
- Ukudibana nolusu okanye amehlo kunokubangela ukucaphuka, ukudibana ngqo nolusu kunye namehlo kufuneka kuphetshwe.
- Xa usebenzisa kwaye ugcina, kufuneka ugcinwe kude nemithombo yomlilo kunye neendawo eziphezulu zokushisa, kwaye ugweme ukudibanisa nee-oxidants.
