Abstract: A PROCESS FOR THE PHOTOCHEMICAL SULFOXIDATION OF N-PARAFFIN COMPRISES IRRADIATING N-PARAFFIN HAVING 10-20 CARBON ATOMS EXCLUSIVELY WITH RADIATIONS WITHIN A LIMITED WAVE LENGTH RANGE, FROM WHICH THE RAYS OF WAVE LENGTHS SHORTER THAN 300 MU WERE CUT OFF IN THE PRESENCE OF SULFUR DIOXIDE AND OXYGEN WHEREBY THE FORMATION OF UNDESIRABLE BROWNISH RESINOUS MATTER IS PREVENTED.
