(57) [Summary] [Problem] When producing tricyclodecane dimethanol from dicyclopentadiene, handling operations such as recovery, extraction separation, and purification of tricyclodecane dimethanol are easy, and productivity is high. Provide an inexpensive manufacturing method. SOLUTION: A dicyclopentadiene is prepared in a lower alcohol-based solvent in the presence of a rhodium compound and a catalyst composed of a phosphite having an electrotonic parameter ν of 2080 to 2090 cm -1 and a steric parameter θ of 135 to 190 °. Hydroformylation to When the solution containing the obtained tricyclodecane dicarbaldehyde is hydrogen reduced in the presence of a hydrogenation catalyst to produce tricyclodecane dimethanol, a tertiary amine compound is added to the hydroformylation reaction solution, It is present in an amount of 50 to 1500 mole times based on the rhodium metal therein. |
