✦ Synopsis

Alkylation of phenol with tert-butyl alcohol (TBA) was carried out in ionic liquids [bmim]PF 6 , [omim]BF 4 , and [hmim]BF 4 . Comparative studies on the catalytic properties of ionic liquids, H 3 PO 4 and some solid acidic catalysts, such as HZSM-5, H-␤, HPW, and HPW/MCM-41, were carried out under identical reaction conditions. Solvent effect has been as well studied. The use of ionic liquids was found to enhance the catalytic properties of the catalysts used.
