Abstract:

In this study, Phosphosulfonic acid supported on nano silica, PSA/Nanosilica, as a novelsolid acid was easily prepared by the simple mixing of Diammonium hydrogen phosphateand chlorosulfonic acid in CH۲Cl۲ at room temperature. The acidic capacity of the catalystwas determined by acid-base titration method.The efficiency of the solid acid was studied in the preparation of symmetrical ethers frombenzylic and aliphatic alcohols. The results showed that PSA/Nanosilica has high potential inthe dehydration of alcohols under solvent-free conditions. So that, the reaction products areproduced with high isolated yields and in short reaction time.
