Impregnated Molecular Sieves as a Catalyst for the Isopropylation of Naphthalene

Abstract:

At refluence temperature, ferric chloride impregnated molecular sieves were prepared by impregnation of FeCl₃ through ion-exchanging methods. The above catalysts were characterized by the means of SEM/EDS (scanning electron microscope/energy dispersion spectrometer) and BET. The catalytic properties on isopropylation of naphthalene and effect of reaction conditions were carried out with fixed-bed flow micro-reactor. We obtained the optimum conditions of this reaction. At this condition, the conversion of naphthalene reaches 44.1%, the yield of 2, 6-DIPN is 41.2% and the selectivity of β,β-DIPN is 85.2%.
