| titleOfInvention | Preparation and recovery of n-alkylethylene diamines from an alkylation mixture using a hydrocarbon solvent and fractional distillation steps |
| abstract | The invention relates to the preparation and recovery of N- alkylethylenediamines by reaction of ethylenediamine with an alkyl halide, in which the N-alkylethylenediamine is obtained substantially free of unreacted ethylenediamine by adding a hydrocarbon solvent to the alkylation reaction mixture, or to a fraction thereof containing the desired product, and then removing unreacted ethylenediamine by azeotropic distillation of the reaction mixture or fraction. |
