Process for separating lye from condensation resins |
| abstract |
In the conventional manufacturing process for condensation resinsnthe resin obtained is first taken up by a solvent and sonThe resulting organic phase is extracted with water to separate the alkali.nIn this way, the resin is released from the basic catalystnwashed. The additional process steps for extraction, recoverynof the solvent and wastewater treatment increase the effort considerably.n n n According to the invention, the alkali is separated from the resin bynthat the resin in a space limited by ion-selective membranesnis exposed to an electrical field, which migrate the alkali from the resinnleaves.n n n Manufacture of low-catalyst condensation resins. |
