Using a similar method to Example 1, a mixture of 400 parts of 3,4,5-trimethoxybenzyl alcohol and 400 parts of acetone with 380 parts of air is passed per hour over the catalyst at 530° C. and 1.2 bar. The residence time is 0.04 second and the throughput is 0.57 tonne/m2.h. 302 parts of 3,4,5-trimethoxybenzaldehyde (in the form of a 44 percent strength by weight solution) are obtained per hour, corresponding to a yield of 76% of theory. The conversion is 95 percent and the space-time yield is 14 grams of 3,4,5-trimethoxybenzaldehyde per cm3 of catalyst volume per hour.
