Procedure

Next, 140 g of a 35% by mass calcium chloride aqueous solution [0.44 mol; corresponding to 0.49 mol (0.98 equivalent) per 1 mol of the fatty acid] was added while stirring to the thus obtained aqueous potassium laurate solution for 30 min. After completion of the addition, the resultant mixture was continuously stirred at 90° C. for 1 h to obtain a calcium laurate slurry. The thus obtained calcium laurate slurry was cooled to 70° C., and then subjected to filtration using a suction filter. Further, 3000 g of tap water was poured on the filter from above to wash the resultant filter cake composed of calcium laurate, and then the calcium laurate cake was dried at 80° C. for 36 h within an air blast dryer, thereby obtaining calcium laurate (Y-2).
