<p>PURPOSE:To produce a hydrogenating catalyst which is originally a catalyst of a homogenous system and easily recovered after use. CONSTITUTION:A reaction product obtained by reacting (C6H5)2P-R-O(CH2)nCOX (wherein R is a p-phenylene group) with a magnetite fine particle absorbing a higher fatty acid Na salt and (C6H5)2P-R-O(CH2)nCOONa thereon or a hydroxyl group-containing polymer having said magnetite fine particle sealed therein is used to prepare an org. solvent suspension and rhodium halide and triphenylphosphine are successively reacted with said reaction product to produce a hydrogenating catalyst.</p> |
