Abstract
Abstract A process for producing a water insoluble metal soap comprising: A. producing an aqueous dispersion of a basic metal carbonate by adding a metal oxide or hydroxide to water and then simultaneously adding aqueous ammonia and gaseous carbon dioxide thereto; B. producing a saponified aliphatic acid aqueous emulsion by emulsifying a liquid aliphatic acid with water with stirring and simultaneously adding a small amount of aqueous ammonia thereto; and C. reacting the intermediate products from steps A and B to produce the desired aliphatic acid metal soap by combining the said intermediate products under high shearing conditions.
