Abstract
L'invention concerne un procédé pour préparer des dérivés de type diaryléthane. Pour préparer un dérivé de type diaryléthane on fait réagir en 1 du styrène ou du styrène substitué avec du m-xylène en présence d'un catalyseur ayant une teneur en acide supérieure à 0,2 mmol/g par suite de la présence de sites acides possédant une fonction d'acidité de Hammett (Ho) inférieure à - 7,5. L'invention s'applique en particulier à la préparation industrielle de dérivés de type diaryléthane avec un rendement élevé.
