Catalytic Study of the Pd@Al2O3 Catalyzed Hydrogenation of Allylbenzene to Propylbenzene in Methanol and Aqueous- Micellar Solutions
The palladium on alumina (Pd@Al2O3)-catalyzed hydrogenation of allylbenzene to propylbenzene was studied in methanol and aqueous micellar solutions of sodium dodecyl sulfate (SDS), decyltrimethylammonium bromide (DTAB), andt-octylphenoxypolyethoxyethanol (TX-100). Over Pd@Al2O3, propylbenzene was ob...

| Summary: | The palladium on alumina (Pd@Al2O3)-catalyzed hydrogenation of allylbenzene to propylbenzene was studied in methanol and aqueous micellar solutions of sodium dodecyl sulfate (SDS), decyltrimethylammonium bromide (DTAB), andt-octylphenoxypolyethoxyethanol (TX-100). Over Pd@Al2O3, propylbenzene was obtained via direct hydrogenation of allylbenzene and isomerization to b-methylstyrene which was hydrogenated afterwards. In aqueous micellar solutions, the reaction was faster than in pure water, but slower than in methanol due to lower hydrogen solubility. In the H2O/SDS system, a higher activation energy was obtained than in methanol. For the investigated surfactants, the initial reaction rate in the micellar systems decreased in the order SDS > TX-100 > DTAB. |
