Title (EN) METHOD FOR CONDITIONING ION EXCHANGERS
(FR) RESINES CATALYSEURS
(DE) VERFAHREN ZUR KONDITIONIERUNG VON IONENAUSTAUSCHERN
Abstract:
(EN) The invention relates to the conditioning and use of ion exchange resins for the production of bisphenols. The invention, in particular, relates to the conditioning of monodispersed cationic and anionic exchangers and the use thereof as catalysts, in particular, as catalysts for condensation reactions. The conditioning is characterised, in particular, in that a) water-wet mono-dispersed ion exchange resin is suspended in demineralised water, b) the mono-dispersed ion exchange resin is subjected to a discontinuous or continuous wash, with acid-free demineralised water, until a constant conductivity is achieved, c) after the last wash, the demineralised water is let off and the mono-dispersed ion exchange resin mixed with the acid-free OH-component, d) the resulting mixture is dried, in a continuously operated recycling apparatus, fitted with a distillation unit and e) finally, the suspension of mono-dispersed ion exchange resin and OH-component is transferred to a reaction flask.
(FR) La présente invention concerne le conditionnement et l'utilisation d'échangeurs d'ions servant à la préparation de bisphénols. Cette invention concerne en particulier le conditionnement d'échangeurs de cations et d'anions monodispersés, ainsi que leur utilisation comme catalyseurs, en particulier pour la catalyse de réaction de condensation.
(DE) Die Anmeldung betrifft die Konditionierung und Verwendung von lonenaustauschern für die Herstellung von Bisphenolen. Die vorliegende Anmeldung betrifft insbesondere die Konditionierung von monodispersen Kationen- und Anionenaustauschern sowie deren Verwendung als Katalysatoren, insbesondere zur Katalyse von Kondensationsreaktionen. Das Konditionieren ist insbesondere dadurch gekennzeichnet, dass man a) wasserfeuchte monodisperse lonenaustauscher in sauerstofffreiem VE-Wasser suspendiert, b) den monodispersen lonenaustauscher einer diskontinuierlichen oder kontinuierlichen Wäsche mit sauerstofffreiem VE-Wasser bis zur konstanten Leitfähigkeit unterzieht, c) nach den letzten Wäsche das VE Wasser ablässt und dem monodispersen lonenaustauscher die sauerstofffreie OH-Komponente zumischt, d) die erhaltene Mischung in einer kontinuierlich betriebenen Umlaufapparatur mit Destillationseinheit entwässert und e) schließlich die Suspension aus monodispersen lonenaustaucher und OH-Komponente in ein Reaktionsgefäß überführt.
