【Abstract】 The catalytic activity of Na 2WO 4 H 2O 2 system on oxidation of 1 methoxy 2 propanol to methoxyacetone was studied. It was found that acidic promoters and additives have great effects on the conversion and selectivity of the reaction: NaHSO 4 is the best acidic promoter, while H 2PO 4 - or HPO 4 2- is harmful to the activity of the reaction; MeOH and CH 3CN can promote oxidation of 1 methoxy 2 propanol. The effect of the amount of MeOH on the yield of methoxyacetone was also studied.更多还原
