Versuchsvorschrift

The catalyst from Example II is then soaked in glacial acetic acid for 15 minutes at ambient temperature. The catalyst is then dried and calcined at 500° C. for 16 hours. Using the same reaction conditions as in Example II, toluene is reacted with ethylene in the presence of such an acetic acid-treated catalyst. Ethylation of toluene gives 7.1% conversion of toluene to produce an ethyltoluene product which contains 92.3% of the para-ethyltoluene isomer.
