Abstract
1. Technical Result Simplification of the technological process, increase in the yield, reduction of the cost of the production, and power expenses. 2. Essence A method comprises reacting a gas phase mixture of methanol and air over a silver catalyst at the 500-6000C temperature. Cooling said gaseous solution at the 1300C flowing in the opposite direction. Separating said aqueous solution and said non-condensable gases and distillation of aqueous formaldehyde – methanol mixture. 3. Field of Application Chemical Industry. 1 ind. cl., and 11 dep. cl. 2 fig.
