Extraction, Characterization of Silica and Immobilized with Amino

this study, silica has been prepared by using in a new three steps method from rice husk. The silica was used as a stationary phase in column chromatography and give interesting results in comparison with the commercial grade silica. This study included functionalized of the prepared silica with 3-chloropropyl (triethoxy)saline to give chlorine end group labeled compound as RHACCl. Sulfamic acid and urea were immobilized onto RHACCl to form heterogeneous catalysts labeled as RHANS and RHAUR respectively. The heterogeneous catalysts were used for hydrolysis of cellulose to glucose.
