PURPOSE:To produce a metallic soap, without leaving unreacted raw materials nor producing by-products, by adding one or more kinds of aluminosilicate compounds to the reaction system, and reacting an aliphatic monocarboxylic acid with the oxide or hydroxide of a metal in water. CONSTITUTION:A metallic soap (e.g. calcium stearate) is produced by reacting an aliphatic monocarboxylic acid such as caprylic acid, caproic acid, capric acid, etc. directly with the oxide or hydroxide of a metal such as Li, Mg, Ca, Sr, Ba, etc. (preferably a univalent or bivalent metal) in water. The reaction is carried out in the presence of 0.01-40wt%, preferably 0.1-20wt%, based on the aliphatic monocarboxylic acid, one or more aluminosilicate compounds (preferably A, X, Y or P type zeolite). EFFECT:The water washing step can be eliminated. USE:Additive for plastics, pigment dispersant, wire drawing agent, mold release agent, additive to sand for shell mold process, etc. |
