The method for preparing epichlorohydrin by directly reacting epichlorohydrin with saturated aqueous solution of potassium iodide was developed. The yield of epichlorohydrin prepared by this method can reach 80% ~ 96%. The effects of reaction temperature, reaction time and The effect of dosage of potassium iodide on the yield was investigated by measuring the complexation of halogenated propylene oxide with potassium picrate, and the effect of self-phase transfer catalyst of epichlorohydrin in the reaction was discussed.
