Participants

Reaction Steps

With stirring and cooling to 55°-60° C., 49.5 g of freshly distilled butyl isocyanate are added dropwise to freshly distilled 3-dimethylamino-1-propylamine under nitrogen in the course of 15 minutes. After 1 hour at 60° C., low boiling constituents are removed at a pressure of 0.1 torr and a maximum bath temperature of 140° C. Yield: 98.7 g (98%) of product of the above structure. Titration: 1 equivalent=208.3 g (theory 201.3 g).
