    摘要: 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.

    摘要: Low viscosity amphoteric surfactants are prepared by quaternization of low diamine content imidazolines by a process in which certain addition and temperature parameters are strictly observed. Imidazolines suitable as a starting material may be obtained by heating fatty acids and aminoethanolamine in an inert solvent until water is eliminated, removing the water formed from the reaction mixture by azeotropic distillation and, finally, distilling off the solvent and the residual amine.
