Abstract

L'invention concerne le domaine du génie chimique et peut être utilisée dans la production de 1,2-dichloroéthane par chloration directe de l'éthylène dans le dichloroéthane liquide. Le but de l'invention est d'accroître la conversion de l'éthylène et d'améliorer la sélectivité de la réaction du chlore et de l'éthylène. Pour réaliser ce procédé, on utilise un réacteur constitué d'un corps vertical (1) et d'une tube central (2) de réaction où s'effectue la circulation forcé du dichloroéthane liquide dans un circuit à circulation verticale dont le débit estimé est Q, sans tenir compte du début d'ébullition du dichloroéthane dans la zone de réaction (5). On introduit ensuite dans le réacteur le chlore et l'éthylène gazeux par des buses de distribution (4) et (6) disposées dans le tube (2). Le chlore et l'éthylène gazeux sont dispersés au préalable dans le dichloroéthane liquide par des buses (11) et (12) d'éjecteurs, et le dichloroéthane liquide est introduit dans la chambre d'admission de chaque éjecteur avec un débit Q¿1 ?représentant entre 1 et 20 % du débit estimé Q de l'écoulement du dichloroéthane liquide.
