Title (EN) RECOVERY OF ALKANOL FROM BLEED STREAMS IN CHLOROPRENE PRODUCTION
(FR) RECUPERATION D'ALCANOL A PARTIR DE COURANTS DE SOUTIRAGE DANS LA PRODUCTION DE CHLOROPRENE
Abstract: front page image
(EN)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.
(FR)Dans l'extraction d'alcools a partir de courants de soutirage de la deshydrochloruration de 3,4-dichlorobutene pour donner du chloroprene dans un melange a deux phases d'eau et d'un alcool, on ameliore le rendement de l'extraction en effectuant l'extraction avec de l'eau a une temperature ne depassant pas 32 C.
