Title (EN) METHOD OF CHLORINE PURIFICATION AND PROCESS FOR PRODUCING 1,2−DICHLOROETHANE
(FR) METHODE DE PURIFICATION DE CHLORE ET PROCEDE DE PRODUCTION DE 1,2-DICHLOROETHANE
Abstract: front page image
(EN)A method of chlorine purification in which crude chlorine containing nitrogen and/or oxygen is purified to separate the nitrogen and oxygen from the chlorine, characterized in that the crude chlorine containing nitrogen and/or oxygen is contacted with 1,2−dichloroethane to cause the 1,2−dichloroethane to absorb the chlorine contained in the crude chlorine; and a process for producing 1,2−dichloroethane which comprises reacting ethylene with the chlorine contained in the chlorine−containing 1,2−dichloroethane.
(FR)La présente invention concerne une méthode de purification de chlore dans laquelle du chlore brut contenant de l'azote et/ou de l'oxygène est purifié pour séparer l'azote et l'oxygène du chlore, caractérisée en ce que le chlore brut contenant de l'azote et/ou de l'oxygène est mis en contact avec du 1,2-dichloroéthane pour amener le 1,2-dichloroéthane à absorber le chlore contenu dans le chlore brut ; et un procédé de production de 1,2-dichloroéthane qui consiste à faire réagir l'éthylène avec le chlore contenu dans le 1,2-dichloroéthane contenant du chlore.
