PURPOSE: To obtain an oxidized substd. saccharide suitable for use as a detergent or cleaner in combination with a surfactant in a high yield by oxidizing a specified saccharide with oxygen (-contg. gas) in an aq. mixture in the presence of a catalyst contg. a group VIII metal of the periodic table.
CONSTITUTION: A saccharide having 8-22C alkyl or 8-22C aliphatic acyl groups which may have up to two OH groups is oxidized with oxygen (-contg. gas) in an aq. mixture in the presence of a catalyst contg. a group VIII metal of the periodic table, preferably a platinum/activated carbon catalyst or a platinum oxide catalyst to obtain the objective compd. having 8-22C alkyl or 8-22C aliphatic acyl groups which may have up to two OH groups, at least one saccharide unit of the formula and up to 60 saccharide units.
