40.3 grams of a 30% (by weight) solution of sodium methylate in methanol (0.224 mole) were added to 100 grams of triethanolamine (0.67 mole), after which the methanol was distilled off by heating to 110° C. 51.6 grams of n-octyl sulfate, Na salt (0.22 mole) were stirred at 20° C. into the solution obtained and the reaction mixture was heated for 4 hours to 200° C. After cooling to 20° C., approx. 160 ml of water were added. Two liquid phases formed. The upper phase was separated off, washed twice with water and dried under a vacuum in a rotary vaporator with gentle heating to approx. 80° C. A brown oily liquid (52 grams) having an amine number of 214 was obtained (the amine number indicates the number of mg of KOH equivalent to 1 gram of the substance).
