Gegebenenfalls kann unter Anwendung von vermindertem Druck oder wasserentziehenden Mitteln gearbeitet werden. Die erhaltenen kondensationsprodukte sind j e nach dem Ausgangsmaterial im allgemeinen feste bis pastenförmige, wachsartige Massen, die sich in Wasser klar oder mit schwacher Trübung lösen. Durch Umsetzung mit Alkali oder den Alkahsalzen schwacher Säuren, wie Natriumacetat, lassen sich daraus die freien Basen bzw. die Salze mit schwachen Säuren gewinnen.The reaction components are preferably used in equimolecular amounts implemented, but there is also a not too great excess of one or the other Component, e.g. B. the amine salt, applicable. The implementation takes place at the Temperatures above 160 ° with the escape of Z molecule water. Possibly can be carried out using reduced pressure or dehydrating agents will. The condensation products obtained depend on the starting material generally solid to pasty, waxy masses that clear in water or dissolve with weak cloudiness.

Example 3 327 parts of stearic acid monoethanolamide and 97 parts of monoethanolamine hydrochloride are mixed with one another and heated to 220 ° for -2 hours. The product obtained is stirred in the molten state with a solution of 82 parts of sodium acetate in zoo parts of water. The compound obtained is a yellowish-white, waxy mass which has excellent plasticizing properties. Example 4 327 parts of stearic acid monoethanolamide and 136 parts of hexamethyleneimine hydrochloride are heated to a temperature of 220 ° for 2 hours. The reaction product is dissolved in 500 parts of water and 80 parts of 50 ° Joiger sodium hydroxide solution are added. The precipitated free amine is converted into the acetate by reaction with 60 parts of acetic acid. This is a waxy mass that is well suited as a plasticizer.
