ABSTRACT:
Catalytic decarboxylation process for 2-ketoaldonic acids by nickel ions characterized in that an aqueous solution of a 2-ketoaldonic acid is put in contact with a resin carrying vinylpyridine groups.
The process allows in particular ribulose, xylulose and erythrulose to be easily obtained.
