Claims (4)

1. Verfahren zur Reinigung von verunreinigtem Bisphenol-A, dadurch gekennzeichnet, daß Bisphenol-A durch fraktionierte schmelzkristallisation in einem dynamischen Rieselfilmkristal lisator gereinigt wird.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß die Reinigung in mehreren Stufen durchgeführt wird.
3. Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß jede Stufe umfaßt
- Kristallisation von Bisphenol-A auf der Oberfläche des Kristallisators durch Verringerung der Temperatur des Wärmeübertragungsmediums graduell von einer Temperatur oberhalb des schmelzpunktes von Bisphenol-A bis die Temperatur der Oberflächen unterhalb der Schmelztemperatur von Bisphenol-A ist, und anschließend Abziehen der nichtkristallisierten Flüssigkeit in einen ersten vorratstank,
- Erhitzen der Oberflächen des Kristallisators graduell in der Weise, daß das kristallisierte Bisphenol-A zu schwitzen beginnt und Sammeln der Auschwitzphase in einen zweiten Vorratstank, und
- schmelzen der verbliebenen Kristallschicht durch Erhöhung der Temperatur.
4. Verfahren nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß orthorhombisches kristallines Bisphenol-A hergestellt wird.
