Guguloth, Vijaya Charan published the artcileStable, reusable MoO3/ZrO2 solid acid catalyst for the synthesis of diphenylmethane viafriedel-craft alkylation under solvent free condition, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is diphenylmethane molybdenum zirconium oxide solid acid catalyst.
A simple method is described for the synthesis of substituted diphenylmethane derivatives in excellent yields by friedel-craft alkylation reaction under solvent free condition using molybdenum promoted ZrO2 solid acid catalyst at 80°C. The MoO3/ZrO2 catalyst has been prepared from using impregnation method followed by calcination at 923K for 6 h in air atm. This catalyst was characterized by various techniques such as SEM, XRD, FTIR, UV DRS, and BET surface area. Zirconia has both acidic and basic properties which can be altered by incorporating suitable promoter atom like Mo which inturn increase the surface area thereby enhance the surface acidity. Impregnation of Mo ions shows a strong influence on phase modification of zirconia from thermodynamically more stable monoclinic to metastable tetragonal phase. Incorporation of promoter Mo will stabilize tetragonal phase which is active in catalyzing reactions. In friedel-craft alkylation MoO3/ZrO2 catalyst was found to be stable, efficient and environmentally friendly, easily recovered by filtration, higher yield of product and can be reusable efficiently.
