1. A method of preparing 3(4),8(9)-bisformyltricyclo[5.2.1.02,6]decane, the method comprising the steps of:
performing a primary hydroformylation reaction while adding dicyclopentadiene dropwise to a reactor having a first temperature and a first pressure in the presence of a catalyst composition including a rhodium-containing catalyst compound and an organophosphorus compound; and
performing a secondary hydroformylation reaction under a second temperature and a second pressure by increasing at least one of the pressure and the temperature of the reactor, after completing the primary hydroformylation reaction
wherein the primary and secondary hydroformylation reactions are performed under a mixed gas atmosphere of hydrogen and carbon monoxide,
wherein the dropwise addition of dicyclopentadiene is performed such that the number of moles of dicyclopentadiene introduced per minute with respect to 1 mmol of the rhodium atom in the catalyst composition is 10 mmol to 10000 mmol, and
wherein the rhodium-containing catalyst compound is used in an amount of 1 ppm to 50 ppm in terms of rhodium, based on the total weight of the dicyclopentadiene.
