Abstract: A method for manufacturing dimethoxymethane is provided to increase the production of dimethoxymethane due to the property of acid existing within a catalyst and to improve the oxidation reaction property in the methanol transformation reaction, compared with a unsupported catalyst by introducing a cation functional group to the mesopore carbon containing nitrogen and using a heteropolyacid catalyst. A method for manufacturing dimethoxymethane comprises a step for passing through the intermediate of dimethoxymethane by an acid-catalyzed reaction and a consecutive oxidation reaction of methanol or producing formaldehyde by the direct oxidation reaction of methanol; a step for preparing methoxymethanol by the acid catalytic reaction between the formaldehyde and methanol; a step for preparing dimethoxymethane by the acid catalytic reaction between methoxymethanol and methanol. In the chemical reaction, the heteropolyacid catalyst which can perform a Bi-functional catalyst of the acid catalytic reaction and oxidation reaction at the same time is used. The heteropolyacid catalyst is fixed to a mesopore carbon containing nitrogen having the average pore size of 2-50nm.
