PROCEDURE

实验过程

In the preparation of the diketonide deriving from D-mannitol acetone is the ketone which is preferentially used. Then, the 1,2,5,6-diacetone D-mannitol is prepared by reacting acetone, to which solid zinc chloride has been added, with D-mannitol with stirring within a temperature range of from 0° C. to +50° C.
