ABSTRACT:
A non-catalytic procedure for reacting polyoxyalkyleneamines with alkylene oxides in the presence of 5 to 15 wt. % water is described. With this inventive procedure the addition of the oxides may be done quickly and at the surprisingly low temperature of between 75.degree. and 85.degree. C. The proportion of tertiary amine in the resulting product is less than 90%, indicating partial alkoxylation. This technique is particularly suitable for propoxylation which is difficult to achieve by conventional means.
