| 摘要 |
A process is provided for the production of formaldehyde from methyl chloride. In the process methyl chloride is oxidized with air over a catalyst to give formaldehyde and hydrogen chloride. In a preferred embodiment of the invention, a mixture of two different catalysts is used, one catalyst to promote the hydrolysis of methyl chloride to methyl alcohol, and the other catalyst to oxidize the methyl alcohol so formed to formaldehyde. The reaction kinetics can be regulated by adjusting the proportion of the two catalysts in the mixture. In this manner, the release of heat from the reaction can be controlled and excessive temperatures in the catalyst mixture can be avoided.
