Abstract
This review explained about methods using hydrogen peroxide to convert allyl ether to glycidyl ether and about obtained epoxy compounds. It was difficult to synthesize the allyl ether with halogen free condition, but efficient systems are developed recently by a transition metal catalyst. There are many examples of epoxidation using zeolite catalyst, but it is necessary to use the tungsten catalysts which can react under bilayer of the organic aqueous layer. About aromatic glycidyl ether, the obtained epoxy compounds have few differences in properties except the chlorine content. But in the case of aliphatic glycidyl ether, because there are many by-products in the epichlorohydrin method, they are totally different resin systems. Especially thermal resistance of aliphatic polyvalent glycidyl ethers are very high, so future development is expected.
