METHOD FOR REDUCING THE CONTENT OF AN UNSATURATED AMINE IN A MIXTURE CONTAINING AN AMINE AND A NITRILE |
摘要 |
The invention relates to a method for reducing the content of an aliphatic, monounsaturated amine (III) in a mixture (IV) containing an aminonitrile (I) or a diamine (II), or mixtures thereof and an amine (III). Said method is characterised in that a) mixture (IV) is reacted with an anionic nucleophile (V) in a quantity ranging between 0.01 and 10 mol per mol of amine (III) in mixture (IV) to obtain a mixture (VI). The invention is also characterised in that b) aminonitrile (I) or diamine (II) or mixtures thereof are removed by distillation from mixture (VI), at a temperature ranging between 50 and 170 ~C and a pressure of between 0.5 and 100 kPa.
