METHOD FOR REDUCING THE CONTENT OF AN UNSATURATED AMINE IN AMIXTURE CONTAINING AN AMINO NITRILE, A DIAMINE, A DINITRILE OR MIXTURES THEREOF |
摘要 |
The invention relates to a method for reducing the content of an aliphatic, monounsaturated amine (IV) in a mixture (V) containing an aminonitrile (I) o r a diamine (II) or a dinitrile (III) or mixtures thereof and amine (IV), whereby: a) mixture (V) is reacted with an anionic nucleophile (VI) in a quantity ranging from 0.01 to 10 mols per mol of amine (IV) in mixture (V) a t a temperature ranging from 50 to 200 ~C while obtaining mixture (VII), and; b) amino nitrile (I) or diamine (II) or dinitrile (III) or mixtures thereof are removed by distillation from mixture (VII) at a temperature ranging from 50 to 200 ~C and under a pressure ranging from 0.1 to 100 kPa while obtaining a bottom product (VIII). The inventive method is characterized in that: c) an amino nitrile (I) or diamine (II) or dinitrile (III) or mixtures thereof are removed by distillation from bottom product (VIII) at a temperature which is lower than that selected in step b).
