Abstract
Styrene oxide is an important precursor to prepare 2-phenyl ethanol (2-PEA) of high quality for its use as a fragrance chemical. Styrene oxide was selectively hydrogenated to 2-PEA with polyurea-microencapsulated (EnCat) Pd, Pd–Rh and Pd–Cu nanocatalysts with methanol as solvent and NaOH as promoter. The catalysts were fully characterized to understand their activity, selectivity, and stability. Pd–Cu EnCat was used for further studies. Complete conversion of styrene oxide with 92% selectivity to 2-PEA was obtained over Pd–Cu EnCat at 333 K and 607.8 kPa. Effects of various parameters were studied to understand the product profile. A bifunctional Langmuir-Hinshelwood-Hougen-Watson (LHHW) mechanistic model was proposed. The kinetics of reaction was established and tested against experimental data. The results are new and provide a green and cost-effective process for the synthesis of 2-PEA.
