PROCESS FOR THE SELECTIVE EPOXIDATION OF UNSATURED (MET)ACRYLIC COMPOUNDS; NEW DIFUNCTIONAL (MET)ACRYLATES THUS OBTAINED

Process for the epoxydation of an unsaturated (meth)acrylic compound of formula: in which R1 is chosen from H and C1-C5 alkyl; R2 is chosen from H, alkyl and aryl; R3 is a linear, branched or cyclic alkylene or oxyalkylene radical containing from 1 to 12 carbon atoms, it being possible for one of th...

Summary:Process for the epoxydation of an unsaturated (meth)acrylic compound of formula: in which R1 is chosen from H and C1-C5 alkyl; R2 is chosen from H, alkyl and aryl; R3 is a linear, branched or cyclic alkylene or oxyalkylene radical containing from 1 to 12 carbon atoms, it being possible for one of the carbon atoms of R2, when the latter is an alkyl radical, to be bonded to one of the carbon atoms of R3 to form a ring; and A is chosen from O, S, NH and NR4, R4 being a C1-C12 alkyl group; by action of hydrogen peroxide on the said unsaturated (meth)acrylic compound at a temperature of between 10 DEG C and 50 DEG C in the presence of at least one catalyst chosen from alkali metal molybdates and pertungstates and in the presence of at least one phase transfer agent.
