Abstract

PURPOSE: To obtain the titled compound useful as a raw material for agricultural chemicals, drugs, and transparent nylon in high yield in high selectivity, by hydrogenating dimethyladiponitrile by the use of a Raney coable catalyst, carrying out purification easily.
CONSTITUTION: Dimethyladiponitrile is hydrogenated at 80W160°C at 20kg/cm2G H2 hyrogen partial pressure for ≥1hr by the use of water slurry of a Raney cobalt catalyst obtained by developing a Raney cobalt alloy in NaOH, catalyst is separated from the reaction solution by a filter, and high-purity dimethylhexamethylenediamine is purified by distillation, etc.
