Abstract

L'invention a pour objet un procédé de clivage d'un dihydroxydiphényl alcane en présence d'un catalyseur basique pour produire un alcényl phénol et/ou ses polymères, caractérisé en ce que : on introduit en continu le dihydroxydiphényl alcane dans un milieu réactionnel organique inerte contenant le catalyseur basique et chauffé sous pression réduite, à un débit tel que la concentration du dihydroxydiphényl alcane dans le milieu réactionnel soit maintenue à une valeur non supérieure à 30 % en poids, clivant ainsi le dihydroxydiphényl alcane dans le milieu réactionnel et distillant ainsi le produit de clivage en continu hors du système réactionnel, et on le recueille. Production aisée d'alcényl phénols à l'échelle industrielle.
