Versuchsvorschrift

The silver behenate dispersion was produced as follows: 25 kg (73.5M) behenic acid was dispersed with stirring at 80° C. in 100L of a 10% solution of Surfactant No. 1 per g behenic acid made up to 250L with deionized water at a temperature of 80° C.; then 36.75L of a 2M aqueous solution of sodium hydroxide was added over a period of 10 to 20 minutes to give a clear solution substantially containing sodium behenate; then 25L of a 2.94M aqueous solution of silver nitrate was added with stirring at a rate of 0.163 moles/moles silver behenate min to convert the sodium behenate completely into silver behenate; and finally ultrafiltration was carried out with a 500000 MW polysulfone cartridge filter at room temperature to concentrate the resulting silver behenate dispersion while adding ammonium nitrate to convert Surfactant No. 1 into its ammonium salt, the final AgBeh-concentration was 20.4% with 0.062 g of ammonium alkyl-phenylsulfonate/g AgBeh, the residual conductivity was 1.0 mS/cm.
