| titleOfInvention | Method for the production of diaminoxylene by continuous hydrogenation of liquid phthalonitrile |
| abstract | The invention relates to a method for the production of diaminoxylene, by continuous hydrogenation of liquid phthalonitrile, on a heterogeneous catalyst, in the presence of liquid ammonia, in a reactor, whereby a part of the reactor product is continuously recycled to the reactor feed as a liquid recycle stream (recirculating loop). A flow of fused phthalonitrile is added as a liquid to the recycle stream around the hydrogenation reactor in a mixing device, whereby the phthalonitrile conversion in the reactor on a single pass is greater than 99 % and the recycle stream comprises more than 93 % by weight of liquid ammonia and diaminoxylene and contains no further solvent for phthalonitrile. |
