Abstract
PURPOSE: To provide a catalyst which improves yield by adding a specific salt of phosphoric acids or boric acids to faujasite type zeolite of which the SiO2/Al2O3 is of specific molar ratios and of which the Na ions are partly substituted with specific elements.
CONSTITUTION: A salt of any of phosphoric acids or boric acids and bivalent or trivalent metals, that is, Mg, Ca, Al, Mn, Fe, Co, Ni, Cu, Zn is added to the faujasite type zeolite of which at least 20% of Na ions are substituted by ions of any of Cs, K or Rb, and of which the molar ratio of SiO2/Al2O3 is about 2:1W8:1. The amt. of addition is about 1W20wt%, and the mixture is thoroughly mixed and molded. If styrene is synthesized from toluene and methanol by using such catalyst, the formation of ethyl benzene is suppressed and the ratio of styrene formation is about 0.95W0.98.
