Procedure

139.9 g of behenic acid and 19.0 g of calcium hydroxide were initially introduced and mixed with stirring at 60° to 65° C. After addition of 0.8 g of acetic acid (0.5%, based on the mixture as a whole), the temperature rose to 85° C. The total stirring time was 30 minutes; a dust-like powder was present after only 2 minutes. The reaction was carried out under a slight vacuum as in Example 1.
