Abstract: The invention relates to a method for production of oxymethylene ether of the general formula CH3O—(CH2O)m—CH3 in a liquid phase process, wherein 1?m?10. In a catalytic reaction, molecular oxygen or an oxygen-containing oxidant and methanol, formaldehyde, and/or methyl formate are used as reactants in a solution and are converted by means of a vanadium-oxygen compound or a salt thereof as catalyst in the solution which vanadium-oxygen compound contains vanadium in the oxidation stage +IV or +V. The catalyst reduced during the catalytic reaction is restored to its starting state by oxidation by means of the molecular oxygen or the oxygen-containing oxidant.
