実験手順

The silver behenate dispersion was produced as follows: dispersing 25 kg (73.5M) behenic acid was dispersed with stirring at at 80° C. in 1 g of a 10% solution of Surfactant Nr 5/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, the final AgB-concentration was 16.7% with 0.07 g of Surfactant Nr 5/g AgB, the residual conductivity was 1.0 mS/cm.
