    • A process for the preparation of polyether polyamines comprising the steps ofA) reacting a polyol with an epihalohydrin in the presence of a catalyst;B) adding an at least equimolar quantity of an aqueous alkali metal hydroxide, based on the weight of catalyst, to the reaction mixture formed in step A);C) distilling volatile constituents from the reaction mixture from step B) at a temperature below about 150.degree. C. and under a pressure below about 1.33.times.10.sup.4 Pa.;D) filtering the reaction mixture remaining after step C) at a temperature in the range of from about 80.degree. C. to about 100.degree. C. to remove insoluble components thereof from the bishalohydrin reaction product; andE) reacting the bishalohydrin reaction product with ammonia and/or an amine in the presence of an alkaline catalyst to form a polyether polyamine.

    • In the production of monoalkylphosphoric acid esters, at least one fatty alcohol or mixtures of fatty alcohols containing from 8 to 18 carbon atoms and preferably from 12 to 14 carbon atoms in a straight chain is/are reacted with a 0.2 to 2 molar excess of polyphosphoric acid at a temperature of 60.degree. to 130.degree. C.; following an after-reaction time of 120 to 300 minutes at a temperature of 95.degree. to 105.degree. C., the product of this reaction is slowly hydrolyzed at 90.degree. to 100.degree. C. with 0.5 to 1.0 mole water, based on the quantity of phosphorus atoms in the reaction mixture, the hydrolysis product is neutralized to a level of from 40 to 65% and preferably to a level of from 50 to 60%, based onthe acid number, with dilute alkali metal hydroxide, and the two phases formed are separated from one another after a residence time of 30 to 180 minutes at a temperature in the range of from 50.degree. to 95.degree. C.
