Sulphated mesoporous silica synthesized from rice husk ash for chalcone production
Chalcone is an aromatic ketone that have important biological properties. It can be prepared by an aldol condensation between a benzaldehyde and an acetophenone in the presence of catalyst. A series of S-MCM-48 (SO 42 / MCM-48) was synthesized in this study. Rice husk ash (RHA), an agriculture waste...

Chalcone is an aromatic ketone that have important biological properties. It can be prepared by an aldol condensation between a benzaldehyde and an acetophenone in the presence of catalyst. A series of S-MCM-48 (SO 42 / MCM-48) was synthesized in this study. Rice husk ash (RHA), an agriculture waste was used as a silica (Si0 2 ) source to synthesis the MCM-48 mesoporous molecular sieves by
mean of hydrothermal method and suiphation medification using sulfuric acid (H2SO4) as the sulphate sources. The pore packing order of the SO4 2-doped material dependend strongly on the synthesis conditions such as aging temperature, pH of reaction mixture and dopant concentration. The physicochemical properties of mesoporous material was characterized by X-Ray diffraction (XRD), surface area
analysis (BET), Fourier- Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analyzer (TGA). A simple preparation method was used to generate strong acidity catalyst by introducing sulphate groups onto the surface of MCM-48. The prepared sulphated MCM-48 has been used to catalyzed benzaldehyde and acetophenone and was analyzed by using GC. The conversion of acetophenone was calculated and the best conversion was 85.5% by using S-MCM48(60) catalysts.
