An object of the present invention is to provide highly pure a-methylstyrene by efficiently removing polar substances present in the a-methylstyrene. The present invention discloses a method for purifying a-methylstyrene by reacting polar substances contained in the a-methylstyrene in the presence of a basic substance, and separating a reaction product of the polar substance and the a- methylstyrene.
La présente invention concerne un a-méthylstyrène de grande pureté obtenu grâce à l'élimination efficace d'une matière polaire présente dans un a-méthylstyrène. L'invention porte spécifiquement sur un procédé qui permet de purifier un a-méthylstyrène, ledit procédé consistant à faire réagir la matière polaire contenue dans un a-méthylstyrène en présence d'une substance basique. Le produit de la réaction de la matière polaire est ensuite séparé de l'a-méthylstyrène.
