Abstract

L'invention porte sur un procédé de fabrication de bisphénol A amélioré de façon à former une bouillie de faible viscosité de cristaux à grands diamètres dans une cristallisation par lots pour permettre un passage sans à-coups d'une cristallisation par lots à une cristallisation continue. Dans l'étape de cristallisation, la cristallisation est amorcée par une opération de cristallisation par lots dans un réservoir de cristallisation. Pendant l'opération de cristallisation par lots, le changement de degré de sursaturation par unité de temps au moment où la concentration de bisphénol A de la solution contenue dans le réservoir atteint saturation est ajusté entre 0,1 et 8°C/h.
