Title
(EN) PROCESS FOR THE PRODUCTION OF ALPHA METHYLSTYRENES
(FR) PROCEDE DE PRODUCTION D'ALPHA-METHYLSTYRENES
Abstract
(EN) The invention provides a process for the production of $g(a)-methylstyrenes. In particular, the invention provides a process for producing $g(a)-methylstyrenes from dimethyl phenyl carbinols using an acid salt, which process produces the $g(a)-methylstyrenes in excellent yield with no significant byproduct formation.
(FR) L'invention concerne un procédé de production d'alpha-méthylstyrènes. En particulier, l'invention concerne un procédé de production d'alpha-méthylstyrènes à partir de carbinols de diméthylphényle, au moyen d'un sel d'acide. Ce procédé permet d'obtenir un excellent rendement d'alpha-méthylstyrènes, avec une formation de sous-produits négligeable.
