| 摘 要： | The system W Ⅵ H 2O 2 has good selectivity for methoxyacetone in oxidation of 1 methoxy 2 propanol. The effects of acid and base additives on selectivity for methoxyacetone were studied. The results showed that the acid additive, i.e. NaHSO 4, was favorable to Na 2WO 4 H 2O 2 system, while the base additive NEt 3 was favorable to other tungsten compounds. A 71 2% of yield of methoxyacetone with 98 9% of selectivity for methoxyacetone was obtained in Na 2WO 4 H 2O 2 NaHSO 4 MeCOMe oxidation system.
