PREPARING METHOD OF HYDRIDOCARBONYLTRIS(TRIORGANOPHOSPHORUS)- RHODIUM

摘要

In the preparation of hydridocarbonyl tris (triorganophosphorus) rhodium from the rhodium compound in the hydroformylation distillation residue as a starting material, the distillation residue containing the deactivated rhodium catalyst compound was treated with an oxidizing agent. In the presence of a mixed gas of carbon monoxide and oxygen, it is converted into a rhodium-carbonyl compound and reacted with a hydroxyl group-containing compound, an alkali metal hydroxide, formaldehyde, and a triorganophosphorus ligand directly without isolation from the reaction solution, It is an organic single phase reaction for synthesizing hydridocarbonyl tris (triorganophosphorus) rhodium in a high yield by post-treatment.
