Abstract (en)
[origin: WO8001910A1] In the extraction of alcohols from bleed streams from the dehydrochlorination of 3,4-dichlorobutene to give chloroprene in a two-phase mixture of water and an alcohol, the efficiency of the extraction is improved by carrying out extraction with water at a temperature of not more than 32`C.
