Isopropylation of naphthalene over mesostructured aluminosilicate nanoparticles with wormhole framework structures

The preparation and catalytic properties in isopropylation of naphthalene of nanosized mesostructured alumiosilicate with worm-like framework structures were presented in this work. Catalytic results showed that, under optmium conditions, the present nanocatalyst exhibited high activity making ca. 90 mol% of naphthalene conversion into mono- ,di- and triisopropyl substituted derivatives. It should be mentioned that, however, the present nanocatalyst showed no considerable selectivity to objective products, and this may be attributed to its somewhat large mesopores in comparsion with microporous alkylating catalysts.
