Aluminum chloride immobilized SBA-15 as a novel catalyst for highly selective synthesis of 2,6-diisopropylnaphthalene
Introduction Liquid-phase Friedel–Crafts isopropylation of naphthalene is currently used in the chemical industry to produce 2,6-diisopropylnaphthalene (2,6-DIPN), which is an important chemical intermediate in the production of advanced polymers and polyesters. 2,6-DIPN is normally synthesized over Lewis acid AlCl3, which is catalytically efficient and commercially available. However, AlCl3 catalyst cannot be regenerated and must be hydrolyzed and disposed of, resulting in a large volume of solid waste. The catalyst makes environmentally problems and produces a variety of isomers with 2, 6-DIPN. To overcome these problems, the highly ordered mesoporous silicate materials with high surface area, large pore size, and large pore volume have been used in the application of catalysis 1-3. Therefore, our work is the immobilization of aluminum chloride on mesoporous SBA-15 for the liquid-phase alkylation of naphthalene.
