摘要：

The catalytic coupling of formaldehyde (FA) and methyl formate (MF) over 12-tungstosilicic acid and its salts has been investigated. H4SiW12O40 and its acidic salts were active in the coupling of FA and MF to methyl glycolate (MG) and methyl methoxy acetate (MMAc). Among the acidic salts, LiH3SiW12 and Mg0.5H3W12 showed much higher activities. Water affected the activities of H4SiW12O40 and was unfavorable for the formation of MC and MMAc.
