Abstract
Official abstract text for this publication.
A method of manufacturing an iron soap is disclosed herein. The method comprising the steps of: reacting, at a temperature equal to or lower than a crystal transition initiation temperature of the iron soap to be manufactured, between a straight-chain saturated fatty acid alkali metal salt aqueous solution having from 12 to 22 carbons and a trivalent iron salt aqueous solution with pH of 0.1 to 5.5 so as to prepare an iron soap slurry; and adjusting pH of the prepared iron soap slurry to from 0.1 to 6.0.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing an iron soap having a content A (%) of free fatty acid being 0.01≤A≤8.0, a content B (%) of water soluble salt being 0.01≤B≤0.5, and a granularity summary value C indicated in Formula (1) being 0.1≤C≤5.0, wherein the iron soap is a salt of a straight-chain saturated fatty acid having from 12 to 22 carbons and an iron, Granularity summary value C =( D 90− D 10)/ D 50 (where 1.0≤ D 50≤40.0) Formula (1) D10: 10% cumulative diameter (μm) of fatty acid metal salt particles on a volumetric basis D50: 50% cumulative diameter (μm) of fatty acid metal salt particles on a volumetric basis D90: 90% cumulative diameter (μm) of fatty acid metal salt particles on a volumetric basis the method comprising the steps of: reacting, at a temperature equal to or lower than a crystal transition initiation temperature of the iron soap to be manufactured, between a straight-chain saturated fatty acid alkali metal salt aqueous solution having from 12 to 22 carbons and a trivalent iron salt aqueous solution with pH of 0.1 to 5.5 so as to prepare an iron soap slurry; and adjusting pH of the prepared iron soap slurry to from 0.1 to 6.0.
