| description | A multilayer cation exchange membrane for use in a chloralkali process comprising an carboxylate layer comprising a fluorinated ionomer containing carboxylate groups on one side of the membrane, an exterior sulfonate layer comprising a fluorinated ionomer containing sulfonate groups on the side of the membrane opposite the carboxylate layer, and an interior sulfonate layer comprising a fluorinated ionomer containing sulfonate groups between the carboxylate layer and the exterior sulfonate layer, the exterior sulfonate layer having an ion exchange ratio greater than about 11.3, and the interior sulfonate layer having an ion exchange ratio less than about 11.
La présente invention concerne une membrane échangeuse de cations multicouche destinée à être utilisée dans un procédé de chloralcali, comprenant une couche de carboxylate comprenant un ionomère fluoré contenant des groupes carboxylate sur un côté de la membrane, une couche de sulfonate extérieure comprenant un ionomère fluoré contenant des groupes sulfonate sur le côté de la membrane opposé à la couche de carboxylate, et une couche de sulfonate intérieure comprenant un ionomère fluoré contenant des groupes sulfonate entre la couche de carboxylate et la couche de sulfonate extérieure, la couche de sulfonate extérieure ayant un rapport d'échange d'ions supérieur à environ 11,3, et la couche de sulfonate intérieure ayant un rapport d'échange d'ions inférieur à environ 11. |
