Abstract
Abstract Metal salts of organic acids are produced rapidly and efficiently by subjecting a reaction mixture that contains a metal oxide, hydroxide, or carbonate, an organic acid that has a melting point above 20° C., and a small amount of water to vigorous agitation in an apparatus having attrition and shearing action at a temperature that is below the melting point of the organic acid and below the melting point of the metal salt that is being produced until substantially all of the organic acid has reacted.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
147 words
The process for the production of finely-divided metal salts of carboxylic acids that comprises the steps of a. forming a reaction mixture that consists essentially of 1. a metal component selected from the group consisting of the oxides, hydroxides, and carbonates of the alkali metals, magnesium, calcium, cadmium, strontium, barium, mercury, nickel, cobalt, lead, copper, and mixtures thereof, 2. a carbxylic acid component having a melting point above 20° C., and 3. from 0.1% to 8.0%, based on the total weight of the metal component and the carboxylic acid component, of water and b. subjecting said reaction mixture to vigorous agitation in an apparatus having an attrition and shearing action at a temperature that is below the melting point of the carboxylic acid component and below the melting point of the metal salt that is being produced until substantially all of the carboxylic acid component has reacted.
Claim 2
Dependent Claim
147 words
The process for the production of finely-divided metal salts of carboxylic acids that comprises the steps of a. forming a reaction mixture that consists essentially of 1. a metal component selected from the group consisting of the oxides, hydroxides, and carbonates of the alkali metals, magnesium, calcium, cadmium, strontium, barium, mercury, nickel, cobalt, lead, copper, and mixtures thereof, 2. a carbxylic acid component having a melting point above 20° C., and 3. from 0.1% to 8.0%, based on the total weight of the metal component and the carboxylic acid component, of water and b. subjecting said reaction mixture to vigorous agitation in an apparatus having an attrition and shearing action at a temperature that is below the melting point of the carboxylic acid component and below the melting point of the metal salt that is being produced until substantially all of the carboxylic acid component has reacted.
Claim 3
Dependent Claim
22 words
The process of claim 1 wherein the reaction mixture formed in Step a) contains from 5.0% to 7.5% by weight of water.
Claim 4
Dependent Claim
25 words
The process of claim 1 wherein the carboxylic acid component of the reaction mixture formed in Step a) has a melting point above 30° C.
Claim 5
Dependent Claim
48 words
The process of claim 1 wherein in Step b) the reaction mixture is subjected to vigorous agitation while at a temperature that is at least 10° C. below the melting point of the carboxylic acid component and the melting point of the metal salt that is being produced.
Claim 6
Dependent Claim
35 words

Claim 7
Dependent Claim
35 words
The process of claim 1 wherein in Step b) the reaction mixture is subjected to vigorous agitation until the metal salt that is being produced contains not more than 0.2% by weight of free acid.
