Abstract
A process is provided for the manufacture of formaldehyde from methyl bromide. In the process, methyl bromide is oxidized with air over a catalyst to give formaldehyde and hydrogen bromide. In a preferred embodiment of the invention, a mixture of two different catalysts are employed, one to promote hydrolysis of methyl bromide to methyl alcohol and the other to promote the oxidation of methyl alcohol to formaldehyde.
