| titleOfInvention | Process for producing xylylenediamine |
| abstract | The invention provides a process for producing xylylenediamine, including supplying a solution of phthalonitrile dissolved in a solvent to a reactor filled with a catalyst and hydrogenating the phthalonitrile to produce xylylenediamine, characterized in that the process includes halting supply of the solution; (2) bringing a washing liquid into contact with the catalyst, the washing liquid having a phthalonitrile content of 3 mass% or less and a xylylenediamine content of 1 mass% or more; and after completion of the contact, resuming supply of the solution, and employing the catalyst continuously in hydrogenation. Through the production process of the invention, the catalyst can be employed continuously for a long period of time, and the catalyst-related cost can be considerably reduced. |
