Procedure
7 g of this catalyst was packed into a quartz reaction tube having an inside diameter of 15 mm in a current of argon. The reaction temperature was maintained at 170°C., and a gaseous mixture consisting of p-xylene, butadiene, n-heptane as a diluent, and nitrogen gas in a molar ratio of 1:5:10:5 was passed through the catalyst layer. The contact time of p-xylene was 24 seconds. The conversion of p-xylene was 43%, and the intended 3-methyl-4-(p-tolyl) butene was obtained in a yield of 8%.
