PCT No. PCT/NL94/00272 Sec. 371 Date Jun. 13, 1996 Sec. 102(e) Date Jun. 13, 1996 PCT Filed Nov. 4, 1994 PCT Pub. No. WO95/12619 PCT Pub. Date May 11, 1995The invention provides a method for the oxidation of carbohydrates with periodate in an aqueous medium, with which method a less than equivalent amount of periodate is used and the periodate is regenerated during the reaction in a separate reaction chamber. The periodate is preferably regenerated electrochemically. The oxidation leads to dialdehyde carbohydrates in which advantageously 30-85% of the available diol groups are oxidized to dialdehyde groups.
