ABSTRACT:
The construction costs of a process for preparing epoxy compounds from aromatic compounds containing an active hydrogen atom reactive with an epihalohydrin by reacting such compounds with an epihalohydrin in the presence of an alkali metal hydroxide while controlling the water content in the reaction mixture and subsequently removing the alkali metal halide salt from the reaction mixture is made less costly by employing a water extraction means to remove the alkali metal halide salts from the reaction product mixture containing the epoxy product.
