Abstract

Procédé continu pour la préparation de bisphénols, selon lequel on fait réagir, dans une zone de réaction au moins deux moles d'un phénol avec un composé carbonylé en présence d'une résine échangeuse d'ions acide, on sépare l'effluent de la zone de réaction en deux courants, le premier courant comprenant le composé carbonylé n'ayant pas réagi, de l'eau et du phénol et le deuxième courant comprenant le bisphénol, des sous-produits de réaction et du phénol et on recueille le bisphénol à partir du deuxième courant. On recycle une partie 5 du deuxième courant 4 à la zone de réaction R avant d'en séparer le bisphénol. On augmente ainsi la concentration du bisphénol sans effet défavorable sur la résine.Continuous process for the preparation of bisphenols, according to which at least two moles of a phenol are reacted in a reaction zone with a carbonyl compound in the presence of an acidic ion exchange resin, the effluent is separated from the two-stream reaction zone, the first stream comprising unreacted carbonyl compound, water and phenol and the second stream comprising bisphenol, reaction by-products and phenol and the bisphenol is collected at from the second stream. A portion 5 of the second stream 4 is recycled to the reaction zone R before separating the bisphenol therefrom. The concentration of bisphenol is thus increased without adverse effect on the resin.
