Popis:	The course of epoxidation of 1,4-bis(allyloxy)butane with hydrogen peroxide in the presence of H3PO4/Na2WO4·2H2O or heteropolyacids: H3PW12O40 and H3PMo12O40 as the catalysts and the ionic liquids as the phase transfer catalysts (cocatalysts) has been investigated. Imidazolium lactates and salicylates with N-alkyl or alkoxy substitute with different length were used as the cocatalysts. The influence of the kind and amount of catalyst on the yield of 1-allyloxy-4-glycidoloxybutane has been determined.
