    摘要: In the dehydrochlorination of 3,4-dichlorobutene-1 to give chloroprene in a two-phase mixture of water and an alcohol, a bleed stream may be taken from the organic phase to prevent high boiling impurities accumulating. Problems in recovering the alcohol from the bleed are overcome by extracting the bleed with water at a volume ratio of water and organic phase brought into contact at the first extraction step of not less than 15:1, or if the organic phase is substantially free of chloroprene, not less than 6:1.
