摘要： Tertiary chelating polyamines are separated and purified from their complex mixtures by selective complexation with metal salts wherein the metal is one selected from the group consisting of sodium, magnesium, iron, zinc, cadmium and mercury. The pure polyamines are thereafter recovered by destabilization of the complex. This invention is particularly useful for separating Nperalkylated commercial polyamine mixtures.

摘要： Ethylene amines are manufactured by a process wherein ethylene dichloride is reacted with ammonia and the mixture is stripped of unreacted ammonia. Sodium hydroxide equivalent to the chloride present is added and large quantities of sodium chloride result. Part of the ethylene amines product is lost when this salt is separated from the product amines. Recovery of the ethylene amines from the salt and production of a substantially amine-free salt is accomplished by the disclosed process involving the recrystallization of the process salt to recover the amines and produce a salt free of organic pollutants.
