Reaction Steps
Copper vanadate on ceramic is used as the catalyst in the reactor described in Example 1 and the temperature of the air bath is adjusted to 250° C. 60 l of air and 32 g of pantolactone are added hourly to the evaporator. 99.0% of the pantolactone are transformed and ketopantolactone is formed with a selectivity of 77.5%.
