Process for the preparation of bis(aminopropyl)aliphatic glycols |
| abstract |
This invention relates to a process for the separation of acrylonitrile used in the cyanoethylation of glycols to produce a bis(cyanoethylated) aliphatic glycol from the resulting glycol which is then reduced with hydrogen to produce the corresponding bis(aminopropyl) aliphatic glycol. In this process, acrylonitrile is reacted with an aliphatic glycol in stoichiometric excess and the acrylonitrile removed from the cyanoethylated glycol by reaction with aliphatic primary or secondary amine prior to effecting the hydrogenation of the cyanoethylated aliphatic glycol in the presence of the acrylonitrile-amine reaction product. The reaction product then can be separated by conventional techniques such as distillation. |
