Procedure

N,N,N",N"-Tetramethyldiethylenetriamine (TMDETA, 24.96 g, 157.2 mmole) and propylene oxide (PO, 9.1 g, 157.0 mmole) were charged to a 50 mL autoclave. The reactor was sealed, the contained air was replaced with nitrogen, the reactor was pressured to 100 psi (689 kPa) with nitrogen, and the contents were heated to 120° C. Analysis of samples withdrawn after 6 and 22 hours showed that little change in composition had occurred after the first 6 hours. After 22 hours, the reaction mixture was cooled to ambient temperature and the product was removed. GC analysis of the crude product showed that it contained 4.8% unreacted TMDETA and 82.3% TMHPDETA.
