Synthesis and Characterization of Functionalize HY Zeolite With Sulfunic Acid, A Micro-meso Structure as an Efficient Reusable Catalyst in Organic Transformations
Abstract:A new class of catalyst has been prepared with sulfunic acid functionalized HY zeolite (HY-N-SO3H) and characterized by FESEM, TEM, FTIR, TGA, XRD and BET. The result show that the catalyst has the micro-meso structure without ordering in the mesophase. Then, two sets of organic reaction were examined to consider of catalytic activity. The micro-meso structure HY-N-SO3H was used as an acidic catalyst to synthesis of coumarins via Pechmann reaction and facile transformation of amines to formamides under solvent… Show more
