Abstract

PROCEDE POUR ABAISSER LE TAUX DE 1,4-DICHLOROBUTENE-2 DANS LES EAUX RESIDUAIRES PROVENANT D'UN PROCEDE INTEGRE DE FABRICATION DU CHLOROPRENE COMPRENANT AU MOINS UNE OPERATION D'ISOMERISATION DES DICHLOROBUTENES ET UNE OPERATION DE DESHYDROCHLORATION DU 3,4-DICHLOROBUTENE-1. ON REUNIT EN H L'EAU RESIDUAIRE DE L'ISOMERISATION AVEC LA SAUMURE DE CHLORURE DE SODIUM PROVENANT DE LA DESHYDROCHLORATION DU 3,4-DICHLOROBUTENE-1 DANS DES PROPORTIONS TELLES QUE LA TENEUR EN CHLORURE DE SODIUM DU MELANGE SOIT LE MELANGE, MAINTENU A UN PH INFERIEUR A 6 ENVIRON, A UNE EXTRACTION EN F AVEC ENVIRON 0,5 A 4 EN POIDS D'UN HYDROCARBURE LIQUIDE. L'EXTRAIT ORGANIQUE EST BRULE ET LE LIQUIDE AQUEUX PEUT ETRE REJETE DANS UNE EAU NATURELLE SANS DANGER DE POLLUTION.
