【 摘 要 】

Studying the activity of any catalyst and selectivity toward special products is easy by selecting a module reaction, and choosing appropriatecondition. In our case the reaction of α- methylstyrene dimerization was a choice to study the activity of mordenite type zeolite crystallized from natural clay mineral (kaolin P-2), and also the selectivity toward dimers.The prepared catalyst in the form of hydrogen showed that the acceptable activity and selectivity to linear dimers were (72.5%), at 80 °C, and atmospheric pressure. Different products from the dimerization of α- methylstyrene over prepared catalyst was investigated, and the conversion rate reached to 73%wt.
