The purpose of this thesis was to find an optimum condition for the formation of the precipitated calcium soaps. The system investigated included the range of alkali addition of 0 to 1.2 pounds per one hundred gallons (#/100 gal.). A direct relationship between the adsorption with an increasing alkali concentration to a maximum of 145 parts per million calcium ion adsorbed to 833.5 ppm oleic acid when .225 (#/100 gal.) is applied. It shows that any higher concentration of an alkali will level out the maximum calcium adsorption to approximately 140 ppm.

It was also found that the alkali demand was an increasing function and eventually leveled out at a maximum concentration.
