Reaction Steps
A mixture of 152 g of 4-oxoisophorone (formula IIa), 150 g of ammonium sulfate, 50 g of Raney Ni and 1 liter of ammonia was charged with 80 bar hydrogen in a 3 liter autoclave at room temperature and then stirred at 180° C. for 20 h. When the uptake of hydrogen was complete, the reaction mixture was let down, taken up in ethanol, filtered and subjected to fractional distillation. 130 g of the diamine of formula Ia having a boiling point of 62 to 65° C. under 0.1 mbar were obtained.
