Abstract
Powdered basic metal soaps having a composition corresponding to the formula (MO).sub.n.M(RCOO).sub.2, where MO represents CaO, ZnO, MgO, BaO, PbO, or a mixed oxide PbO/CaO, CaO/ZnO, BaO/CdO, or BaO/ZnO, M is one of the metals mentioned above, RCOO represents an anion of a fatty acid containing 8 to 34 carbon atoms, and n has a value of 0.2 to 2, may be obtained by reaction of powdered fatty acids with powdered metal oxides in the presence of small amounts of water, alcohol, and/or an acid at temperatures between ambient temperature and 100.degree. C. and under a pressure not greater than ambient. Preferably, there is continuous removal of water formed during the reaction, and the reaction mixture is present as free flowing particles throughout the reaction.
