A process for the epoxydation of olefinic compounds

THE PROCEDURE INCLUDES THE REACTION OF SUCH COMPOUNDS WITH HYDROGEN PEROXIDE INTRODUCED AS SUCH OR PRODUCED BY SUBSTANCES UNDER REACTION CONDITIONS, IN THE PRESENCE OF SYNTHETIC ZEOLITES THAT HAVE ATITES OF TITANIUM: 1 X2: 1 WHERE X IS IN THE RANGE FROM AROUND 0.0001 TO AROUND 0.04 AND OPTIONALLY, IN THE PRESENCE OF ONE OR MORE SOLVENTS, A TEMPERATURE IN THE RANGE FROM 0 TO AROUND 150 C AND A PRESSURE FROM 1 TO AROUND FROM 100 ATM. SYNTHETIC ZEOLITES ARE TREATED WITH ALKALINE SUBSTANCES BEFORE AND / OR DURING THEIR USE IN REACTION OR ALTERNATIVELY SYNTHETIC ZEOLITES ARE NEUTRALIZED WITH ACID WITH A COMPOUND SUCH AS X-SI- (R) 3 WHERE X IS SELECTED, CL , CH3CON-SI- (CH3) 3, CF3COON-SI- (CH3) 3, (R) 3-SI-NH, AND AN IMIDAZOLYL GROUP, AND R IS CHOSEN BETWEEN AN ALKYL, ARYL OR ALKYLARYL GROUP.
