Reaction Steps
Nickel 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 270° C. 100 l of air and 32 g of pantolactone are subsequently added hourly to the evaporator. 99.2% of the pantolactone are transformed and ketopantolactone is formed with a selectivity of 79.8%.
