Performance of supported ionic liquid phase and nano gold catalystsover titania support for hydroformylation of ethylene
Abstract
Ligand Triphenylphosphine Trisulfonate for synthesizing of Supported Ionic Liquid Phase (SILP) catalyst was prepared by reaction between Sulfuric acid fuming and Triphenylphosphine in the absence of oxygen. While gold nanoparticle catalyst were synthesized by impregnation of gold hydroxide from Aurochloric acid HAuCl4 (41.1 wt% Au, Chempur) on the TiO2 supportusing solution of NH3 (25%) to adjust pH. In the other procedure, gold hydroxide and titanium hydroxide were co-precipitated from a mixed solution of HAuCl4 and Titanium (IV) Isopropoxide (Merck) which was then heated at 90oC for 3 days. Results of catalyst characterization by various techniques revealed that Supported Ionic Liquid Phase catalyst for hydroformylation reaction of ethylene exhibits better activity than Au/TiO2 catalyst. Studies on gold nanoparticle also showed that selectivity of main product was affected by size of gold clusters.
