| titleOfInvention | Production method of xylylenediamine |
| abstract | In the method of the present invention, xylylenediamine is produced by a two-stage hydrogenation of a dicyanobenzene compound. In a first stage (a), the hydrogenation is performed until a conversion of nitrile groups reaches 90 mol% or higher and less than 99.9 mol%. In a second stage (b), the hydrogenation is further continued at temperatures 10 DEG C or more higher than in the step (a) until the conversion of nitrile groups reaches a level which is higher than that attained in the step (a) and equal to 99.5 mol% or more. In the present invention, a highly pure xylylenediamine containing a minimized amount of cyanobenzylamine is efficiently produced in a simple manner without needing a specific purification, and also without deteriorating the use efficiency of the catalyst while reducing the amount of the dicyanobenzene compound remaining not reacted and the generation of the intermediate cyanobenzylamine. |
