Isingeniso
4,4′-Dimethylbenzophenone. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-4,4′-dimethylbenzophenone:
Ikhwalithi:
I-4,4′-I-Dimethylbenzophenone iwukuqina kwekristalu engenambala engancibiliki kahle emanzini ekamelweni lokushisa, kodwa incibilika kuzincibilikisi zemvelo ezifana notshwala nama-esters.
Ukusetshenziswa: Ingasetshenziswa futhi njengendawo ephakathi ku-organic synthesis yokuhlanganiswa kwezinye izinhlanganisela.
Indlela:
Indlela yokulungiselela evame ukusetshenziswa ilungiswa ukusabela kwe-benzophenone ne-n-butylformaldehyde ngaphansi kwezimo ze-alkali. Izinyathelo ezithile zokuhlanganisa zingase zihlanganise ukukhiqizwa kosawoti we-diazonium we-ketones noma i-oxime, eyehliswa ibe yi-4,4′-dimethylbenzophenone.
Ulwazi Lokuphepha:
Iphrofayili yokuphepha ye-4,4′-dimethylbenzophenone iphezulu, kodwa okulandelayo kufanele kuqashelwe:
- Ingase icasule amehlo nesikhumba, ngakho thatha izinyathelo zokuphepha lapho uyisebenzisa.
- Gwema ukuhogela uthuli noma ukuthinta isixazululo salo ukuze ugweme ukungaphatheki kahle noma ukungezwani komzimba.
- Gwema ukuthintana namalangabi avulekile ngesikhathi sokusebenzisa, futhi ugcine kude namalangabi avulekile namazinga okushisa aphezulu.
- Sebenzisa ngaphansi kokuqondisa kochwepheshe futhi ulandele izinqubo zokuphepha ezifanele.
