Isingeniso
I-4-Biacetophenone iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-4-biacetophenone:
Ikhwalithi:
- Ukubukeka: I-4-Biacetophenone iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo.
- Ukunambitha: Iphunga.
- Ukuncibilika: akuncibiliki emanzini, kuncibilika kuzincibilikisi zemvelo ezifana notshwala, i-ether, njll.
Sebenzisa:
- I-4-Biphenyacetophenone iyindawo ebalulekile ephakathi ku-organic synthesis, engasetshenziswa ukuhlanganisa inhlanganisela yezinto eziphilayo, njenge-triphenylamine, i-diphenylacetophenone, njll.
Indlela:
I-4-Biacetophenone ingalungiswa ngokusabela kwe-acylation, futhi indlela evamile iwukusabela i-acetophenone nge-anhydride, eyenziwa ngaphansi kwezimo ze-acidic.
Ulwazi Lokuphepha:
- 4-Biphenyacetophenone inobuthi obuphansi ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Njengazo zonke izinto zamakhemikhali, izinyathelo ezifanele zokuphepha kufanele zithathwe lapho kusingathwa.
- Ukuthinta isikhumba noma amehlo kungase kubangele ukucasuka, ukuthintana ngqo nesikhumba namehlo kufanele kugwenywe.
- Uma usebenzisa futhi uyigcina, kufanele igcinwe kude nemithombo yomlilo nezindawo ezishisa kakhulu, futhi ugweme ukuthintana nama-oxidants.
