The system WⅥ-H2O2 has good selectivity for methoxyacetone in oxidation of 1-methoxy-2-propanol. The effects of acid and base additives on selectivit y for methoxyacetone were studied. The results showed that the acid additive, i.e. NaHSO4, was favorable to Na2WO4-H2O2 system, while the base ad ditive NEt3 was favorable to other tungsten compounds. A 71.2% of yield of me thoxyacetone with 98.9% of selectivity for methoxyacetone was obtained in Na2 WO4-H2O2-NaHSO4-MeCOMe oxidation system.
