Alkylation of 2-naphthol with tripropylene in the presence of zeolite catalysts H-BEA, H-Y and H-MFI was studied. Comparative studies on the catalytic properties of H-BEA, H-Y and H-MFI zeolites were carried out under identical reaction conditions. The results showed that the H-BEA catalyst exhibited outstanding catalytic performance; and the conversion and selectivity of 2-naphthol could be 52.1% and 86.3%, respectively. It was found that the structure and acid strength of zeolite catalysts were the major influencing factors for the conversion and selectivity of 2-naphthol alkylation.
