Conditions

Temperature: 60 °C

Procedure

While cooling with dry ice, 0.9 kg of dimethylamine (20 mol) from a reservoir bottle was condensed into a cold trap. A 10 l Büchi stirred autoclave with gas inlet tube, stirrer, internal thermometer and pressure equalizer was initially charged with 3.5 kg of cyclohexane and 5.65 kg of technical-grade oleic acid (20 mol), which were heated to 60° C. until the mixture became homogeneous. By slowly thawing the cold trap, gaseous dimethylamine was passed through the gas inlet tube into the stirred autoclave. In a strongly exothermic reaction, the oleic acid N,N-dimethylammonium salt formed.
