| Abstract: | A novel method,employing sodium methandate as the neutralizer for ethylenediamine hydrochloride is developed to extract hydrochloride.Because of the low boiling point of methanol,it is not only easier for separation and purification of ethylendiamine,but also lower for the energy consumption.By the operations of neutralization,desalination,dehydration and distillation,high purified enthylenediamine can be obtained with 94% productive ratio. |
