Abstract:
Provided is a hydrogenation method of a phthalate compound. According to the present invention, stereoselectivity of the hydrogenation reaction may be increased, and thus the content of a cis isomer in a product may be increased. As a result, quality of the hydrogenation product as a plasticizer may be improved.
