<p>of the disclosure: A process for the manufacture, of polyalkylenepolyamines by reacting a primary or secondary ? with a compound of the formula (I) where X is -Cl, -Br or -OSO3H and R1 and R2 are H or saturated alkyl of 1 to 4 carbon atoms, and with at least the stoichiometric amount, based on the compound of the formula I, of an aqueous solution, of from 15 to 45 per cent strength, of an alkali metal hydroxide or alkaline earth metal hydroxide, at from 60 to 200.degree.C, cooling the reaction mixture to a temperature at which 2 phases form, and separating off the upper phase, containing polyalkylenepolyamines. The rate of reaction can be increased by adding catalytic amounts of compounds which initiate the polymerization of alkyleneimines.</p> |
