Intshayelelo
I-Dimethyldione yikhemikhali enegama lekhemikhali i-methylbenzophenone. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-dimetethone:
Umgangatho:
- Imbonakalo: Ulwelo olungenambala okanye olutyheli olucacileyo olucacileyo.
- Ukunyibilika: Ukunyibilika emanzini, utywala kunye nezinyibilikisi ze-ether.
- Ivumba: Ngevumba elimnandi elikhethekileyo.
Sebenzisa:
- I-Dimethyldiketone isetyenziswa ngokubanzi kwi-chemical synthesis njenge-solvent, i-agent yokunciphisa kunye ne-catalyst.
- Ingasetyenziselwa njengento ebalulekileyo ephakathi kwi-organic synthesis kwaye ithatha inxaxheba kwi-synthesis yeentlobo ezahlukeneyo ze-organic compounds.
Indlela:
- Indlela esetyenziswa ngokuqhelekileyo yokulungiselela i-benzoic acid kunye ne-sulfuric acid okanye i-phosphoric acid ukufumana i-benzoyl chloride, kwaye emva koko iphendule nge-methanol kunye ne-sodium carbonate ukufumana i-dimethyldione.
- Kukho ezinye iindlela ezininzi zokulungisa i-dimethyldione, njenge-chloroformic acid kunye ne-phenylisocyanate reaction, nge-chloroazobenzene kunye ne-protonated dimethylamine reaction, njl.
Ulwazi ngoKhuseleko:
- I-Dimethyldiketone yi-organic compound kunye ne-toxicity ethile, kwaye ukuvezwa ngokugqithiseleyo okanye ukuphefumla kunokubangela umonakalo kumzimba womntu.
- Imethadiketone kufuneka igcinwe kwisikhongozeli esingangeni moya, kude nendawo evuthayo kunye nee-oxidants.
-Nxiba iiglavu zokukhusela kunye neglavu xa usebenzisa kwaye unqande ukudibana nolusu okanye amehlo.
- Iinkqubo ezifanelekileyo zokusebenza zokhuseleko kunye nezikhokelo kufuneka zilandelwe kwibhubhoratri okanye iinkqubo zokuvelisa ishishini.
