Rh-supported ionic-liquid catalysts on TiO2 for the conversion of Ethylene to propanol

Abstract

Rhodium catalyst systems for hydroformylation has been researched widely in the literature. Using ionic liquid for rhodium-supported catalyst facilitates this reaction. In this work, TiO2 support was first time used. From the FT-IR, EPR, and surface area analysis, the components of supported ionic liquid phase can be seen after the impregnation of ionic liquid into the support’s porous structure. The main product for the ethylene conversion is propan-2-ol, as a subsequent hydrogenation product after hydroformylation. Pressure and temperature difference are evaluated to understand the influence on selectivity and product formation.
