ている。2. Description of the Related Art The hydroformylation reaction of carbon monoxide and hydrogen on various olefins is one of the important reactions currently practiced in the chemical industry as a method for synthesizing aldehydes or alcohols. However, all of this reaction is carried out by a liquid phase homogeneous reaction using a rhodium complex or a cobalt complex as a catalyst, it is difficult to separate the catalyst from the reaction product or solvent, and the production cost due to the use of various solvents increases. There are major problems in terms of temperature rise, catalyst recovery, regeneration, and life.
