Epoxidation of 1,4-diallyloxybutane to 1-allyloxy-4-glycidyloxybutane by the method of phase transfer catalysis
The epoxidation of 1,4-diallyloxybutane (DiAB) with 30 wt% hydrogen peroxide in the presence of phosphorotungstic acid (PTA) hydrate or phosphoric(V)-acid-sodium tungsten(VI) dihydrate system (PO43-/WO42-)as the catalysts and an onium salt as a phase transfer catalyst has been investigated. The influence of the type and amount of epoxidation catalyst, the molar ratio of 1.4-diallyloxybtitane to H2O2, the amount and nature of auxiliary solvent on the course of the epoxidation was studied.
