Procedure

A suspension prepared from 55.0 g of granulated stearic acid (An 198, titer 66° C., particle size 100-300μ) and 8.1 g lithium hydroxide monohydrate in 550 ml of water is heated to 80° C. within 10-15 minutes. The remaining free fatty acid at this point is only 12.1%. Stirring is continued at 80° C. for the duration of one more hour and the resultant hollow granulate, which now contains only 0.4% free fatty acid, is filtered and dried.
