PURPOSE: To obtain a high-purity granular metallic soap, by adding previously an aluminosilicate compound to an aliphatic monocarboxylic acid in water, reacting the carboxylic acid with a metal oxide or a metal hydroxide at a reaction temperature lowered to ≤ the melting point of the carboxylic acid.
CONSTITUTION: In preparing a metallic soap by reacting directly an aliphatic monocarboxylic acid with a metal oxide or a metal hydroxide in water, one or more aluminosilicate compounds (preferably A type, X type Y type or P type zeolite) are suspended in hot water in which the aliphatic monocarboxylic acid and water are heated to ≥ the melting point of the aliphatic carboxylic acid. Then, the system is cooled to ≤ the melting point, the metal oxide or metal hydroxide is added to the system, and the system is heated to ≤ the melting point to carry out the reaction. Selection of an amount of the aluminosilicate compound added can improve required performances.
USE: An addition agent for plastic, dispersant for pigment, agent for wire drawing, drawing, releasant, etc.
