Definitions

  • the conditioning can be carried out in a wide temperature range. Usually, at temperatures between 20 and 180 0 C, preferably 50 to 130 0 C, worked. Particularly preferably, a temperature ramp is passed through, in which the catalyst, starting at a moderately elevated temperature, preferably between 20 and 50 0 C, slowly up to the desired later for the hydrogenation reaction temperature, preferably 50 to 130 0 C, heated.
  • the diamine yield is 3% higher than without conditioning. This is due, on the one hand, to the higher conversion (less intermediate isophorone aminonitrile in the product) and, on the other hand, to the higher selectivity (lower proportion of the cyclic by-products amidine and imine).
  • the experiments were carried out in a 1 L hydrogenation autoclave equipped with a catalyst basket (static basket with stirrer, "Mahoney type").
  • the catalyst basket was filled in each case freshly with 80 mL of a spherical cobalt Raneytyp fixed-bed catalyst.
  • the reactor was first filled with about 500 ml of ammonia and kept under stirring for about 2 h at 50 0 C and 250 bar. Thereafter, the ammonia was vented by venting the reactor.
