Process for the preparation of clay loaded metal complexes catalyst and a process for the hydrogenation of oils using the catalyst so prepared

摘要

The process disclosed is for the preparation of clay loaded metal complex hydrogenation catalyst which is particularly suitable for the hydrogenation of oils and other unsaturated compounds such as Jojoba oil and castor oil. In the process, a platinum group metal complex MXn wherein M is a platinum group metal, X is a halide and n is 1, 2, 3 or 4 is refluxed with a donor substituted phosphine or arsine ligand and clay in the presence of an organic solvent. The solution is precipitated and dried. The catalyst so obtained is cheap.
