Abstract: Ethylation of toluene with ethanol has been examined over MnAPO-46, NAPO-46 and ZAPO-46 catalysts at 300, 350, 400 and 450oC. The products obtained are benzene, styrene, m-ethyltoluene and diethyl ether. Toluene conversion is maximum at 350°C. Formation of diethyl ether is high at 350 °C, but it decreases with increase in temperature due to prevention of ethanol adsorption on active sites. The yield of m-ethyl toluene which is the largely expected product in this investigation increases with increase in the acidity of the catalyst. Among the three catalysts studied, toluene conversion and yield of m-ethyltoluene are more over highly acidic MnAPO-46 catalyst.
