В заявке описан способ получения параксилола метилированием толуола в присутствии связанного цеолитом цеолитного катализатора. Этот катализатор включает первые цеолитные кристаллы, которые связаны между собой вторыми цеолитными кристаллами. При применении для метилирования толуола до параксилола селективность связанного цеолитом цеолитного катализатора в отношении параксилола превышает ту, при которой достигается его термодинамически равновесная концентрация. Эту селективность можно повысить селективированием катализатора.Международная заявка была опубликована вместе с отчетом о международном поиске.
