Provided is a hydrogenation method of a phthalate compound. According to the present invention, in the hydrogenation reaction, generation of by-products is suppressed, and thus catalytic activity is improved and life-time is extended, thereby increasing efficiency of a commercial process and economic efficiency. Further, since the hydrogenation product prepared by the present invention has high purity and a low acid value, its quality as a plasticizer is excellent, thereby being applied to a variety of products.

Process for hydrogenation of phthalate compound

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.
