Abstract: AN ORGANIC COMPOUND HAVING AT LEAST ONE C-C DOUBLE BOND IS EPOXIDIZED BY MEANS OF HYDROGEN PEROXIDE IN THE PRESENCE OF AT LEAST ONE CATALYTICALLY ACTIVE COMPOUND AND AT LEAST ONE SOLVENT, WHEREIN A PRODUCT MIXTURE COMPRISING -HYDROPEROXYALCOHOLS IS REDUCED USING AT LEAST ONE REDUCING AGENT. THE PROCESS ADVANTAGEOUSLY COMPRISES AT LEAST THE FOLLOWING STEPS: (I) REACTING AN ORGANIC COMPOUND HAVING AT LEAST ONE C-C DOUBLE BOND WITH HYDROGEN PEROXIDE IN THE PRESENCE OF AT LEAST ONE CATALYTICALLY ACTIVE COMPOUND AND AT LEAST ONE SOLVENT TO GIVE A PRODUCT MIXTURE P1 COMPRISING A-HYDROPEROXYALCOHOLS; (II) SEPARATING AN EPOXIDE FORMED IN THE REACTION IN STEP (I) AND THE UNREACTED ORGANIC COMPOUND HAVING AT LEAST ONE C-C DOUBLE BOND FROM P1 OR P1' TO GIVE A PRODUCT MIXTURE P2 OR P2', WHERE P2 COMPRISES THE -HYDROPEROXYALCOHOLS FORMED AS BY-PRODUCT IN THE REACTION IN STEP (I) AND P2' IS LARGELY FREE OF -HYDROPEROXYALCOHOLS; (III) TREATING P1 AND/OR P2 WITH AT LEAST ONE REDUCING AGENT SO THAT THE -HYDROPEROXYALCOHOLS ARE CONVERTED INTO CORRESPONDING GLYCOLS TO GIVE A PRODUCT MIXTURE P1' OR P3.
