ABSTRACT:
Alcohols such as those containing from about 1 to about 10 carbon atoms may be converted to aldehydes by treating the alcohols with an oxygen-containing gas such as air or oxygen in the presence of a catalyst comprising at least two oxides of metals selected from the group consisting of molybdenum, tungsten, cobalt, nickel, manganese, iron and chromium, at least one of said oxides being molybdenum oxide or tungsten oxide composited on a high surface area support. The conversion reaction may be effected at a temperature ranging from about 200.degree. to about 400.degree. C. and a pressure in the range of from about atmospheric to about 50 atmospheres. By employing this particular catalyst, good conversion rates and high selectivity to the aldehydes will be obtained.
