METHANOL SELECTIVE OXIDATION TO DIMETHOXYMETHANE ON H3PMO12040/SBA-15SUPPORTED CATALYSTS

摘要

@@IntroductionDimethoxymethane (DMM: CH3OCH2OCH3) is an important chemical intermediate. It is used as a gasoline additive, as a building block in organic syntheses, and as a precursor in the synthesis of concentrated formaldehyde (HCHO) streams and of polyoxymethylene dimethyl ethers useful as diesel fuel additives. In contrast with the two steps synthesis of DMM, the one-stage synthesis of DMM from CH3OH: 3CH,OH+1/2O2 → CH3OCH2OCH3+2H2O has received limited attention and achieved limited success[1].
