| Abstract: | Alkylation of phenol with isopropanol was camed out in HMCM -56 molecular sieves catalyst. The effects of various reaction parameters such as reaction temperature, reactant ratio （ molar ratio of isopropanoll to phenol）, catalyst loading and space velocity on catalyst performance were discussed. Employing analytical and spectroscopic techniques XRD showed a HMCM -56 structure with highly ordered crystalline structure. Optimal reaction conditions ： T = 220 ℃ ,WHSV = 3.0 h^-1 , catalyst loading = 0.3 g, nIPA/nphenol=0.8, phenol conversion rate of 75% ,the total of selectivity O -isopropyl phenol and isopropyl phenol was 65% . |
