Abstract
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.
