ABSTRACT:
The invention provides a process for epoxidizing an olefinic double bond in an olefinically-unsaturated compound by contact of a liquid phase mixture containing the olefinically-unsaturated compound, an aldehyde having at least two carbon atoms and a suitable solvent with molecular oxygen in the presence of a catalyst which is soluble in the reaction mixture and which comprises a praseodymium compound. The process has particularly advantageous application to oxidation of aldrin to dieldrin.
