الإجراء التجريبي

An autoclave provided with a stirrer, a thermometer, a pressure gauge and a pressure dropping funnel was charged with 250 g of N-methyloctadecylamine and heated to 160° C. Then 45 g of ethylene oxide was occasionally added dropwise thereto under a pressure of 0 to 6 kg/cm2G. Three hours were required for completing the addition. Next, the resulting mixture was aged, i.e., maintained, at 160° C. for 2 hours and then cooled. The reaction mixture was taken out and distilled to thereby give 250 g of N-(2-hydroxyethyl)-N-methyloctadecylamine. This product had a boiling point of 185° to 190° C./0.2 mmHg.
