Reaktionsschritte

An aqueous solution of sodium salicylate was prepared by adding 43.2 g of 2N sodium hydroxide to 12 g of salicylic acid in 240 g of demineralized water. This aqueous solution was simultaneously added with 120 mL of a 0.588 M aqueous solution of silver nitrate over a period of 10 s to 280 mL of a stirred aqueous solution containing 160 mL of a 5% aqueous solution of GAFAC ™ RM710 (an alkylphenyl- polyethene oxide-phosphate from GENERAL ANILINE), 80 mL of a 2% aqueous solution of NATRASOL™ 250L (a hydroxyethylcellulose from AQUALON) and 40 mL of demineralized water. 160 mL of a 5% aqueous solution of PIGMENTVERTEILER™ N (a sodium salt of polyacrylic acid from BASF) was then added to the resulting dispersion.
