Abstract

PROCEDE D'ENLEVEMENT DE CHLOROPRENES A PARTIR DE DICHLORURE D'ETHYLENE ET NOUVEAU PRODUIT AINSI OBTENU. DANS CE PROCEDE, ON SOUMET DES COURANTS DE DICHLORURE D'ETHYLENE A LA DISTILLATION DANS UNE ZONE DE DISTILLATION DANS LAQUELLE DU CHLORE GAZEUX LIBRE EST INTRODUIT, EN CHLORANT AINSI LES CHLOROPRENES QUI Y SONT CONTENUS ET EN FORMANT DES PRODUITS CHLOROCARBONES A POINT D'EBULLITION SUPERIEUR, EN TANT QUE PRODUITS REACTIONNELS; LES PRODUITS CHLOROCARBONES A POINT D'EBULLITION SUPERIEUR, AVEC LE DICHLORURE D'ETHYLENE, PEUVENT ETRE RETIRES SOUS FORME DE PRODUITS DE QUEUE ET ENVOYES A UNE SECONDE ZONE DE DISTILLATION POUR LA SEPARATION DE DICHLORURE D'ETHYLENE A PARTIR D'IMPURETES A POINT D'EBULLITION SUPERIEUR. LA PRESENTE INVENTION EST PARTICULIEREMENT UTILE POUR FOURNIR DES COURANTS DE DICHLORURE D'ETHYLENE EXEMPTS D'IMPURETES FORMEES DE CHLOROPRENES, CES COURANTS POUVANT ETRE ENSUITE RECYCLES DANS UNE ETAPE DE CRAQUAGE POUR FORMER DU CHLORURE DE VINYLE.
