Selelekela
4,4'-Dimethylbenzophenone. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhahisoleseling ea polokeho ea 4,4′-dimethylbenzophenone:
Boleng:
4,4′-Dimethylbenzophenone ke kristale e tiileng e se nang 'mala e sa qhibiliheng hantle metsing ka mocheso oa kamore, empa e qhibiliha ka har'a li-solvents tse kang alcohols le esters.
Tšebeliso: E ka boela ea sebelisoa e le motsoako oa motsoako oa organic synthesis ea metsoako e meng.
Mokhoa:
Mokhoa o tloaelehileng oa ho itokisa o lokisoa ke karabelo ea benzophenone le n-butylformaldehyde tlas'a maemo a alkaline. Mehato e khethehileng ea ho kopanya e ka kenyelletsa ho hlahisa letsoai la diazonium la ketone kapa oxime, tse fokolitsoeng ho 4,4'-dimethylbenzophenone.
Lintlha tsa Tšireletseho:
Boemo ba polokeho ea 4,4'-dimethylbenzophenone bo phahame, empa tse latelang li lokela ho hlokomeloa:
- E ka 'na ea halefisa mahlo le letlalo, kahoo e-ba hlokolosi ha u e sebelisa.
- Qoba ho hema lerōle kapa ho thetsa tharollo ea lona ho qoba ho se thabise kapa ho hanana le lintho tse itseng.
- Qoba ho kopana le malakabe a bulehileng nakong ea ts'ebeliso, 'me u boloke hole le malakabe a bulehileng le mocheso o phahameng.
- Sebelisa tlas'a tataiso ea setsebi 'me u latele mekhoa e nepahetseng ea tšireletso.
