反応手順
A mixture of iron (III) oxide and molybdenum trioxide (G-105 from Girdler) is used as the catalyst in the reactor described in Example 1 and the temperature of the air bath is adjusted to 225° C. 60 l of air and 33 g of pantolactone are subsequently added hourly to the evaporator. 96% of the pantolactone are transformed and ketopantolactone is formed with a selectivity of 83%.
