Procedure

1.9 g of Sodium hydroxide dissolved in 100 ml of water and 12 g of lauric acid in 100 ml of toluene were mixed to emulsify (at 25° C.) the same. An aqueous solution of 8.5 g of silver nitrate dissolved in 50 ml of water was then added to the emulsion. Upon five minutes' storage, the emulsion separated into a silver laurate-containing toluene phase and an aqueous phase. After removal of aqueous phase, the toluene phase was dispersed into 200 ml of ethanol, and then silver laurate collected by centrifugation. 12 g of spindle-like silver laurate crystals about 3μ in longer diameter was obtained. (Instead of toluene which was used in the above procedure, benzene, pentene, cyclohexane, butyl acetate, isoamyl acetate, butyl alcohol, tricresyl phosphate, dibutylphthalate, and the like can be used, and silver laurate obtained similarly to the above.)
