実験手順
In a 26-liter tank, 1.65 kg (12.0 mol) of 2-anilinoethanol are dissolved at room temperature in 1.53 l of ethanol and subsequently admixed with 4.58 l of water with stirring. The solution is heated to 38° C. 4.07 kg (3.0 equivalents) of chloroacetyl chloride and 6.60 kg of 45% sodium hydroxide solution (6.2 equivalents) are then added simultaneously at an internal temperature of 38 to 43° C. within 60 to 80 minutes, so that the pH is kept between 12 and 12.5. The mixture is stirred at a pH of 12 to 12.5 for 10 minutes, then cooled to 2° C. and stirred at this temperature for 30 minutes. The precipitated product is filtered off and washed twice with 3.3 kg each time of demineralized water at 2° C. The moist product is dried to constant mass at 50° C. under reduced pressure.
