The present invention relates to a novel organic compound and an organic light emitting device including the same, and more specifically provides an organic electroluminescent device with remarkably improved light emitting efficiency and service life.

Organic compound and organic electroluminescent device including the same

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.
