Procedure

The solution in which 54.4 g of behenic acid were dissolved in 1200 ml of toluene, was added with 2400 ml of water and the aqueous solution thus obtained was homogenized by means of a high-speed homogenizer. Ammoniacal silver nitrate solution of 400 ml containing 27.2 g of silver nitrate were dropped into said solution, taking 30 minutes with keeping the temperature of the reacting solution at 60° C. under agitation and the further agitation was applied thereto for another 30 minutes, and then the crystals thus produced were filtrated, washed, cleaned with methanol and dried up under reduced pressure in succession, and thus 65.0 g of silver behenate were obtained.
