실험 절차

Agitated in a reaction vessel are 116 parts of 1,6-hexamethylenediamine with 380 parts of O-octyl carbamate and 130 parts of n-octanol-(1) at a reflux temperature of 185° C.-205° C. for 2 hours while the ammonia is removed by distillation. At this point, an additional 500 parts of n-octanol-(1) are allowed to flow into the reaction mixture and the reaction is continued at reflux temperature for 7 hours. The reaction mixture, cooled to 110° C., is filtered, and the reaction product is allowed to crystallize by cooling. By filtration, washing with n-octanol-(1) and drying, 388 parts of 1,6-bis(octoxycarbonylamino)hexane are obtained corresponding with 90.6 percent theory relative to 1,6-hexamethylenediamine. The melting point is 107° C.-109° C.
