Abstract

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.
