| Abstract: | ZnCl 2 modified NaY solid L-acid catalysts were prepared by solid-state reaction and characterized by XRD and NH 3-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 ZnCl 2 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 ZnCl 2 (10%)/NaY were up to 86.7% and 99.3% respectively. |
