Selelekela
Dimethyldione ke ntho ea lik'hemik'hale e nang le lebitso la lik'hemik'hale methylbenzophenone. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea dimetethone:
Boleng:
- Ponahalo: Mokelikeli o hlakileng o se nang 'mala kapa o mosehla o bobebe.
- Solubility: Ho qhibiliha ka metsing, joala le lihlapolli tsa ether.
- Monko: Ka monko o monate o khethehileng.
Sebelisa:
- Dimethyldiketone e sebelisoa haholo ka lik'hemik'hale tsa lik'hemik'hale e le mokelikeli, moemeli oa ho fokotsa le ho kenya letsoho.
- E ka sebelisoa e le setsi sa bohlokoa sa lipakeng ho manyolo a manyolo mme e nka karolo ho kopantseng mefuta e fapaneng ea metsoako ea manyolo.
Mokhoa:
- Mokhoa o tloaelehileng oa ho itokisa ke ho itšoara ka benzoic acid ka sulfuric acid kapa phosphoric acid ho fumana benzoyl chloride, ebe o itšoara ka methanol le sodium carbonate ho fumana dimethyldione.
- Ho na le mekhoa e meng e mengata ea ho lokisa dimethyldione, joalo ka chloroformic acid le phenylisocyanate reaction, ka chloroazobenzene le protonated dimethylamine reaction, joalo-joalo.
Lintlha tsa Tšireletseho:
- Dimethyldiketone ke motsoako oa manyolo o nang le chefo e itseng, 'me ho pepeseha ho feteletseng kapa ho hema ho ka baka tšenyo' meleng oa motho.
- Methadiketone e lokela ho bolokoa ka har'a sets'oants'o se sa keneng moea, hole le ho chesoa le li-oxidants.
- Apara liatlana tse sireletsang le likhalase ha u sebelisa le ho qoba ho kopana le letlalo kapa mahlo.
- Mekhoa le litataiso tse amanang le ts'ireletso li lokela ho lateloa lits'ebetsong tsa tlhahiso ea laboratori kapa indastering.
