A mesoporous aluminum silicate molecular sieve (MASM) with the Si/Al molar ratios of 25, 50, 100 and
150 was one pot synthesized with aluminum isopropoxide, tetraethylorthosilicate and
cetyltrimethylammonium bromide by sol-gel method by using acetylacetone (acac) as chelating agent. XRD,
N2 sorption, high resolution transmission electron microscopy and 27Al-NMR, investigation showed that a
mesoporous molecular sieves with wormhole framework structure is formed. The synthesized MASM with
the Si/Al molar ratio of 25 successfully catalyze the alkylation of phenol with 1-octene at 160 0C in liquid
phase to the monoalkyl substituted product quantitatively
