Reaction Steps
A molten stearic acid (29.5 grams, Hystrene 7018) was added gradually to a stirred mixture of zinc oxide (4.9 grams), phosphoric acid (0.1 gram), Tergitol 15-S-7 (0.2 gram), and water (66 grams) at 65° C. The reaction mixture was stirred at 60-70° C. for one hour, cooled to 25° C., filtered, and dried to afford 32.4 grams (98.8% yield) of zinc stearate white powder having 0.1% water, 14.3% ash, 0.44% by weight of free fatty acid, and a melting point of 126° C.
