ZnCl₂ modified NaY solid L-acid catalysts were prepared by solid-state reaction and characterized by XRD and NH₃-TPD.The Zn content in the catalysts was determined by ICP-AES.The catalytic properties of the catalysts in the etherification of cathechol with methanol were examined in a fixed bed micro-reactor.The results indicated that ZnCl₂ modified NaY showed higher catalytic activity than HY with B acid sites in etherification.In the optimum reaction conditions,the conversion of catechol and the selectivity for guaiacol over ZnCl₂(10%)/NaY were up to 86.7% and 99.3% respectively.
