Procedure

In a glass tube reactor was placed aluminium-exchanged bentonite particles (20 ml) prepared as described in B above through which was passed a mixture of benzene and ethylene in a molar ratio of 8:1. The residence time was 10 seconds, the temperature of the reactor was 386° C. and the pressure was atmospheric. An ethylene conversion to ethyl benzene of 6.1% was obtained. The weight ratio of ethyl benzene to diethyl benzenes was about 32:1 The selectivity of both benzene and ethylene to ethyl benzene was approximately 95%.
