    Abstract: Etherified polyoxyalkylene derivatives of the formula where R1 is hydrogen, C1-C20-alkyl or C3-C5-alkenyl, R2 and R3 independently of one another are each hydrogen, methyl or ethyl, R4 is C1-C4-alkyl and m and n are identical or different and are each greater than or equal to 0, with the proviso that the sum of m and n is from 3 to 300, are prepared by reacting the corresponding hydroxyl-containing polyoxyalkylene derivative with a dialkyl sulfate in the presence of an alkali metal hydroxide by a process in which the reaction is carried out at from 20 DEG to 60 DEG C. in the presence of an aqueous solution of an alkali metal hydroxide, the concentration of alkali metal hydroxide during the entire duration of the reaction being not less than 35% by weight, based on the aqueous phase, and not less than 1 mole of dialkyl sulfate and not less than one mole of alkali metal hydroxide are used per mole equivalent of organic hydroxyl groups.

    Abstract: A process for the manufacture of polyalkylenepolyamines by reacting a primary or secondary amine 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 percent strength, of an alkali metal hydroxide or alkaline earth metal hydroxide, at from 60 DEG to 200 DEG C., cooling the reaction mixture to a temperature at which 2 aqueous phases form, and separating off the upper phase, containing polyalkylenepolyamnines. The rate of reaction can be increased by adding catalytic amounts of compounds which initiate the polymerization of alkyleneimines.
