Procedure
A five-liter, four-necked reaction flask fitted with a reflux condenser, mechanical stirrer, thermometer and a dropping funnel was charged with 996.6 g (4.0 moles) of 1,3-bis(dimethylaminopropyl)urea of 92.5 percent purity. This compound was prepared by the method described in U.S. Pat. No. 4,157,388. The contents of the flask were chilled by immersion into an ice-water bath, and 788.4 g (8.0 moles) of 37 percent hydrochloric acid was added at such a rate as to keep the temperature below 48° C. To the well-agitated 1,3-bis(dimethylaminopropyl)urea dihydrochloride solution so obtained, 740.0 g (8.0 moles) of epichlorohydrin was added slowly, taking care that the temperature did not exceed 48° C. After this addition was completed, the solution was kept at 45°-48° C. for one-half hour and then heated at 70° C. for another 30 minutes. A 77.3 percent equeous solution of the title compound was obtained.
