Abstract: With increasing phosphorus content, the MCM-22 zeolite acidity was reduced and the quantity of weak acid sites increased gradually, whereas the strong acid sit es decreased. A proper phosphorus content can improve the selectivity for 2-dod ecylbenzene and the catalytic stability of the MCM-22 catalyst. The maximum yie ld of 2-phenyldodecane was obtained with a phosphorus content of 0.5%.

Key words: MCM-22 zeolite, phosphorus modification, benzene, 1-dodecene, alkylation
