ABSTRACT:
The present invention relates to a process for preparing ultrapure epichlorohydrin from epichlorohydrin containing technical impurities, by fractional distillation under particular conditions, preferably with continuous operation, that yield a product of very high purity and very low content of halogenated hydrocarbons. Epoxy resins made with such ultrapure epichlorohydrin are especially well suited for use in fabricating electrical components and microchips.
