Claim 3:
4. A method of preparing a composition comprising tricyclodecane dimethanol; one or more of C11-12 diol compounds represented by the following Formula 1-1 and Formula 1-2, wherein the total content of the C11-12 diol compounds is 10% by weight to 20% by weight, the method comprising the steps of:
performing a hydroformylation reaction by introducing a catalyst composition including a rhodium-containing catalyst compound and an organophosphorus compound into a reactor, and by adding dropwise dicyclopentadiene under a mixed gas of hydrogen and carbon monoxide; and
performing a hydrogenation reaction of tricyclodecane dialdehyde obtained by the hydroformylation reaction in the presence of a hydrogenation catalyst,
wherein the dicyclopentadiene includes 4% by weight to 20% by weight of co-dimers of C4-5 diene and cyclopentadiene:, in Formula 1-1,
R1 and R2 are each independently hydrogen or methyl, provided that both R1 and R2 being methyl is excluded,, in Formula 1-2,
n is 3 or 4,
when n is 3, R3 is hydrogen or methyl, and
when n is 4, R3 is hydrogen.
