Procedure

An amount of 100 g of L-sorbose, 1400 ml of hydrous acetone containing water in amounts of 1500 ppm, and 30 ml of concentrated sulfuric acid were placed in a 3 l-capacity flask. The mixture was reacted at 30° C. under stirring and under a reduced pressure for 1.5 hours in the same manner as in Example 1 except that the same hydrous acetone as above was used as an additive acetone, to provide 94.6 g (65.5% yield) of diacetone sorbose.

Workup

  1. customThe mixture was reacted at 30° C.
