Abstract

L'INVENTION CONCERNE UN PROCEDE POUR MAINTENIR LA SELECTIVITE CATALYTIQUE PAR RAPPORT AU CHLORURE DE VINYLIDENE DANS LA DECHLORHYDRATATION CATALYTIQUE EN PHASE VAPEUR DU 1,1,2-TRICHLOROETHANE. DANS LA PRODUCTION DE CHLORURE DE VINYLIDENE PAR LA DECHLORHYDRATATION THERMIQUE CATALYSEE D'UN MELANGE GAZEUX DE 1,1,2-TRICHLOROETHANE ET D'UN DILUANT NON REACTIF A UNE PRESSION TOTALE ELEVEE, LA SELECTIVITE CATALYTIQUE PAR RAPPORT AU CHLORURE DE VINYLIDENE EST MAINTENUE EN REGLANT LA PRESSION PARTIELLE DU 1,1,2-TRICHLOROETHANE DANS LE GAZ D'ALIMENTATION. AMELIORATION DE LA SELECTIVITE DE LA FORMATION DE CHLORURE DE VINYLIDENE PAR RAPPORT A LA FORMATION D'ISOMERES DU 1,2-DICHLOROETHYLENE.THE INVENTION RELATES TO A PROCESS FOR MAINTAINING CATALYTIC SELECTIVITY IN RELATION TO VINYLIDENE CHLORIDE IN THE VAPOR-PHASE CATALYTIC DECHLORHYDRATION OF 1,1,2-TRICHLOROETHANE. IN THE PRODUCTION OF VINYLIDENE CHLORIDE BY THE CATALYZED THERMAL DECHLORHYDRATION OF A GAS MIXTURE OF 1,1,2-TRICHLOROETHANE AND A THINNER NOT REACTIVE TO HIGH TOTAL PRESSURE, THE CATALYTIC SELECTIVITY OF VINYLOROETHANE IS RELATED TO MAIN CHLORIDIDE ADJUSTING THE PARTIAL PRESSURE OF 1,1,2-TRICHLOROETHANE IN THE SUPPLY GAS. IMPROVEMENT OF THE SELECTIVITY OF THE FORMATION OF VINYLIDENE CHLORIDE COMPARED TO THE FORMATION OF 1,2-DICHLOROETHYLENE ISOMERS.
