<p>An economical and industrial method for dehydrogenating triisopropylbenzene to produce diisopropylisopropenylbenzene, isopropyldiisopropenylbenzene, and/or triisopropenylbenzene, which comprises using a solid catalyst consisting mainly of an iron compound and a potassium compound or a solid catalyst consisting mainly of an iron compound, a potassium compound, and a magnesium compound as a catalyst for the dehydrogenation to conduct the reaction. The dehydrogenation of triisopropylbenzene or diisopropylbenzene with the aid of either of the solid catalysts is continuously conducted with intervals of catalyst regeneration with steam, oxygen, or air. Thus, the life of the catalyst is prolonged. The dehydrogenation method is economical and is suitable for and superior in industrial production.</p> |
