| titleOfInvention | Preparation method of dimethyl sulfoxide as well as used catalyst and catalyst composition thereof |
| abstract | The invention relates to the field of organic synthetic chemistry, in particular to a preparation method of dimethyl sulfoxide as well as used catalyst and catalyst composition thereof. The general formula of the catalyst is aFe2O3.bCuO2.cMnO2.dRuO2.eRh2O3.fAl2O3, wherein a, b and c are selected from 0 to 15 independently, and d, e and f are selected from 0.01 to 10 independently. The catalyst composition comprises the catalyst and photosensitizer with the mass ratio of 1:0.1 to 10. The catalyst/catalyst composition has efficient catalytic activity, oxygen is taken as single oxidant during a process of preparing dimethyl sulfoxide through catalysis, and compared with a conventional nitric acid technique and a potassium permanganate method, the preparation method has the advantages that during preparation, any hazardous substances can not be caused, and pollution is not caused to the environment. |
