Abstract

Satd. aldehydes contg. >3C are prepd. by passing primary alkanols contg. >3C atoms in the gaseous phase, at elevated temp. over catalyst contg. Pd. The reaction can be effected at reduced, normal or high pressures. Temps. of 50-250 degrees C and pressures of 0.1 to 3 atmos. are suitable. The catalyst contains Pd as metal or as a compound, pref. on a support such as Al2O3 or SiO2 in a concentration on the support of 0.01 to 10%, pref. 0.1-2% wt. Other metals or metal compounds may be used with the Pd.
