HYDROGENATION METHOD OF PHTHALATE COMPOUND |
摘要 |
There are provided a method for hydrogenation of a phthalate compound. According to the method for hydrogenation of the present invention, a hydrogenation reaction is performed in a multi-pipe type reactor in a state in which a viscosity of only a liquid-phase phthalate based raw material is lowered, such that a yield of a hydrogenation reaction process may be improved, and operation stability and economical efficiency on a commercial scale may be improved by hot spot control. According to another method of the present invention, long-term activity of a catalyst used in a reaction is maintained, and performance of the catalyst may be improved, such that stability and economical efficiency of a hydrogenation process may be improved. Therefore, a total amount of the catalyst required in the reaction may be decreased, and a replacement cycle may be extended, thereby making it possible to improving operation stability of the process and economical efficiency at the time of performing the process on a commercial scale. |
