The Heterogenation Of Saccharin, Melamine And Sulfonic Acid Onto Rice Husk Ash Silica And Their Catalytic Activity In Esterification Reaction

The Heterogenation Of Saccharin, Melamine And Sulfonic Acid Onto Rice Husk Ash Silica And Their Catalytic Activity In Esterification Reaction

Sodium silicate from rice husk ash (RHA) was functionalized with 3– (chloropropyl)triethoxysilane (CPTES), 3–(mercaptopropyl)trimethoxysilane and 3–(aminopropyl)triethoxysilane to give RHACCl, RHAPrSH and RHAPrNH2 via a simple one–pot synthesis. The 29Si MAS NMR of RHACCl showed the presence of T2,...
