Reaction Steps

An ammonium stearate solution was prepared by mixing 113.5 grams of stearic acid with 567 grams of ammonia/carbon dioxide solution containing 12% of ammonia and 10% of carbon dioxide. The solution was sprayed onto 756 grams of zinc clay R591, then the mixture was mixed well and heated to 60° C. The resulting powder was heated at 110° C. for 18 hours. The dried powder was attrition milled again and then sieved with a 140 mesh sieve. The product was jet milled with the Nissen jet mill (see Example 2) to produce zinc stearate clay RC. There is some loss of material through dusting at the various milling processes. Its properties are listed below:
