Procedure

To 100 ml of water at 60° C. temperature 23.3 g of barium hydroxide octahydrate is added and into this suspension 50.0 g of behenic acid in flakes form (AN 165, titer 75° C.) is incorporated so that a paste is obtained having an acid/water ratio of 1:2. This paste is then reacted for 15 minutes at 60° C. followed by 15 minutes at 80° C. temperature. When the melting point of the fatty acid is exceeded, momentary viscosity increase takes place requiring vigorous mixing of the mass. The remaining water which has now a pH of 7 is decanted and the resultant granulate consisting of fractured hollow spheres is dried. The free fatty acid content of the end product is 1.3%.
