Procedure

A silver behenate emulsion was prepared by adding a solution of 6.8kg of behenic acid in 67L of 2-propanol at 65° C. to a 400L vessel heated to maintain the temperature of its contents at 65° C., converting 96% of the behenic acid to sodium behenate by adding with stirring 76.8L of 0.25M sodium hydroxide in deionized water and finally adding with stirring 48L of a 0.4M solution of silver nitrate in deionized water. Upon completion of the addition of silver nitrate the contents of the vessel were allowed to cool and the precipitate filtered off, washed, slurried with water, filtered again and finally dried at 45° C. for 12 hours.
