Title (EN) RECOVERY OF ALKANOL IN CHLOROPRENE PRODUCTION
(FR) RECUPERATION D'ALCANOL DANS LA PRODUCTION DE CHLOROPRENE
Abstract: front page image
(EN)In the extraction of an alcohol from an organic phase resulting from the dehydrochlorination of 3,4-dichlorobutene to give chloroprene in a two-phase mixture of water and an alcohol, undesirable emulsification is prevented by the addition of sufficient acid to reduce the pH to below 5.
(FR)Dans l'extraction d'un alcool d'une phase organique resultant de la deshydrochloruration de 3,4-dichlorobutene pour donner du chloroprene dans un melange a deux phases d'eau et d'un alcool, on empeche l'emulsification indesirable par addition suffisante d'acide pour ramener le pH en dessous de 5.
