실험 절차

Using a similar method to Example 1, a mixture of 300 parts of 3-(p-tert.-butylphenyl)-2-methyl-1-propanol and 200 parts of water with 250 parts of air and 250 parts of nitrogen is passed per hour over the catalyst at 560° C. and 1.1 bar. The residence time is 0.025 second and the throughput is 0.42 tonne/m2.h. 211 parts of 3-(p-tert.-butylphenyl)-2-methylpropanal (in the form of a 77 percent strength by weight organic phase) are obtained per hour, corresponding to a yield of 71% of theory. The conversion is 95 percent and the space-time yield is 10 grams of 3-(p-tert.-butylphenyl)-2-methylpropanal per cm3 of catalyst volume per hour.
