Gas-phase carbonylation of dimethoxymethane (DMM) to methylmethoxyacetate (MMAc) over cesium salts of 12-tungstophosphoric acid (CsхH3-хPW12O40) was studied for the first time. Among the studied catalysts, Cs2.5H0.5PW12O40 showed the best performance: the MMAc yield and productivity amounted to 40 % and 2.4 mmol • g-1 • h-1, respectively at mild conditions: Т = 110 °С, P = 10 atm, GHSV = 6000 h-1 and DMM/CO = 4/76 mol/mol. Catalysts were characterized by BET, XRD, TEM, FTIR techniques. Based on the data obtained, the nature of the active centers, origin of the observed catalytic activity order and probable mechanism of DMM carbonylation over CsхH3-хPW12O40 were discussed.
