Abstract:
The instant invention is directed to aminomethyl cyclododecanes selected from the group consisting of aminomethyl cyclododecanes, bis-(aminomethyl)-cyclododecanes, tris-(aminomethyl)-cyclododecanes and mixtures thereof. The invention is also directed to a process for producing aminomethyl cyclododecanes, bis-(aminomethyl)-cyclododecanes, tris-(aminomethyl)-cyclododecanes, and mixtures thereof comprising reacting cyclododeca-1,5,9-triene with carbon monoxide and hydrogen in the presence of a rhodium-containing catalyst at temperatures of from 80.degree. to 180.degree. C. and under pressures of from 30 to 900 bars, separating the catalyst off from the hydroformylation product and treating the hydroformylation products with hydrogen at from 50.degree. to 150.degree. C. in the presence of ammonia and a hydrogenation catalyst, optionally after separating by distillation into the individual components.
