Procedure

500 g of distilled water were mixed with 3500 g of n-Dodecenylsuccinic Anhydride (98% concentration, Milliken Chemical Company, Inman, S.C.) at 70 degrees Centigrade for approximately 16 hours. Following the 16 hour reaction period, 3070 g of a 1% sodium sulfate solution was added and mixed for one more hour and removed from heat. 1000 g of a 50% sodium hydroxide solution was then slowly added to the emulsion with constant mixing to form a 49% concentration of the n-Dodecenylsuccinic acid monosodium salt. From this, a representative sample was obtained and diluted to 6% concentration with distilled water and the pH was adjusted to 9 with sodium hydroxide solution to form the n-Dodecenylsuccinate Disodium Salt.
