<p>An oxidation catalyst for lower alcohols which makes it possible to convert lower alcohols such as methanol into partial oxidates such as dimethoxymethane selectively and efficiently through direct oxidation of the alcohols; and a process for preparing dimethoxymethane or other partial oxidates from lower alcohols such as methanol selectively and efficiently by using the catalyst. Specifically, dimethoxymethane or other partial oxidates of lower alcohols can be prepared by gas-phase catalytic oxidation of a lower alcohol with a gas containing molecular oxygen in the presence of an oxidation catalyst for lower alcohols containing as the active ingredient a rhenium antimony double oxide such as SbRe2O6. When the gas-phase catalytic oxidation is conducted at 300 to 400 °C, dimethoxymethane can be prepared particularly highly selectively.</p> |
