Abstract
A process is presented for the continuous oxidation of alditols to aldoses accompanied by under 20 weight percent of aldonic and/or alduronic acids relative to the aldoses that are formed. The use of zerovalent platinum on a support such as theta-alumina and at superatmospheric oxygen partial pressures up to about 1,000 pounds per square inch is partially successful in affording good conversion of alditols with relatively low aldonic and/or alduronic acid formation.
