Reaction Steps
Silver 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 27 g of pantolactone are subsequently added hourly to the evaporator. 98.4% of the pantolactone are transformed and ketopantolactone is formed with a selectivity of 84.4%.
