Isingeniso
I-Dimethyldione iyikhemikhali enegama lekhemikhali i-methylbenzophenone. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-dimetethone:
Ikhwalithi:
- Ukubukeka: Uketshezi olusobala olungenambala noma oluphuzi olukhanyayo.
- I-Solubility: Incibilika emanzini, otshwaleni nasezincibilikisini ze-ether.
- Iphunga: Ngephunga elimnandi elikhethekile.
Sebenzisa:
- I-Dimethyldiketone isetshenziswa kabanzi ekuhlanganiseni kwamakhemikhali njenge-solvent, i-ejenti yokunciphisa kanye ne-catalyst.
- Ingasetshenziswa njengento ebalulekile ephakathi ku-organic synthesis futhi ibamba iqhaza ekuhlanganiseni izinhlobonhlobo zezinhlanganisela eziphilayo.
Indlela:
- Indlela evame ukusetshenziswa yokulungisa iwukusabela i-benzoic acid ne-sulfuric acid noma i-phosphoric acid ukuze kutholwe i-benzoyl chloride, bese kusabela nge-methanol ne-sodium carbonate ukuze kutholwe i-dimethyldione.
- Ziningi ezinye izindlela zokulungisa i-dimethyldione, njenge-chloroformic acid kanye ne-phenylisocyanate reaction, nge-chloroazobenzene kanye ne-protonated dimethylamine reaction, njll.
Ulwazi Lokuphepha:
I-Dimethyldiketone iyinhlanganisela yezinto eziphilayo ezinobuthi obuthile, futhi ukuchayeka ngokweqile noma ukuhogela kungabangela umonakalo emzimbeni womuntu.
- I-Methadiketone kufanele igcinwe esitsheni esingangenisi umoya, kude nokuvutha kanye nama-oxidants.
- Gqoka amagilavu okuzivikela kanye nezibuko lapho usebenzisa futhi ugweme ukuthinta isikhumba noma amehlo.
- Izinqubo zokusebenza zokuphepha ezifanele kanye nemihlahlandlela kufanele kulandelwe elabhorethri noma izinqubo zokukhiqiza zezimboni.
