METHOD OF SELECTIVELY REMOVING SMALL QUANTITY OF BETAACHLOROACROLEIN AND 5*66EPOXYHEXENEE1 FROM EPICHLOROHYDRIN AND EPICHLOROHYDRIN PRODUCED THEREBY

摘要

Beta-chloroacrolein and 5,6-epoxyhexene-1 impurities present in minor amounts in epichlorohydrin are selectively removed with minimal concomitant destruction of epichlorohydrin by hydrogenation in the presence of a catalyst comprising rhodium, platinum or palladium deposited on a non-acidic, refractory support.
