Abstract: Aseries of phenyl-functionalized-MSUmesoporous molecular sieves were synthesized under neutral condition in the presence of biodegradable non-ionic polyethylene oxide(AEO9).By subsequent sulphonation of the phenyl rings attached to the silica framework, the phenylsulphonic acid functionalized MSUderivatives could be obtained.Their structure and property of the organo-modified mesoporous molecular sieves were studied by means of XRD, FT IR, TEM, HRTEM, 13C MAS NMR, 29Si MAS NMR, N2adsorption/desorption and probe reaction techniques.The results showed that the so-produced organo modified mesoporous molecular sieves featured bimodal pore size distribution and the pore channel was similar to those in the MSU(worm-like). The organo modified mesoporous molecular sieves containing phenylsulphonic acid active sites, used as solid acid catalyst, showed a much higher catalytic activity for the formation of2,2-pentamethylene1,3-dioxolane(cyclic ketal) from ethylene glycol and cyclohexanone

Key words: Organic functionalozatio, MSU mesoporous molecular sieves, Double pore distribution, Solid acid catalyst
