Selective, high purity preparation of N-monoalkyl alkylenediamines |
| abstract |
A continuous method of preparing N-monoalkyl alkylenediamines, uncontaminated by the N,N'-dialkyl alkylenediamine, is based on the observation that the disubstituted material selectively precipitates from aqueous media. A scheme is presented where an aqueous alkylenediamine is reacted with a suitable carbonyl component and hydrogen over a supported platinum catalyst. Where the alkylenediamine forms an azeotrope with water it can be conveniently recycled to the reactor. |
