Ionothermal Crystallization of SAPO-11 using novel pyridinium ionic liquid and its catalytic activity in esterification of levulinic acid into ethyl levulinate

A study using a novel pyridinium ionic liquid, namely 1-propylpyridinium bromide (PPy]Br), to crystallize SAPO-11 under ionothermal conditions is reported. By carefully following the crystallization process, SAPO-11 can readily be crystallized in the presence of PPy]Br, which serves as a synthesis s...
