The phase behaviors of the system aluminum stearate, palmitate, and laurate-Nujol are studied by differential thermal analysis. Phase diagrams are obtained, and it is found for stearate and palmitate that soaps dissolve in hydrocarbon at the lower transition points of the soaps, and that the higher transition points disappear by addition of hydrocarbon. Differences in phase behaviors are found between laurate and other soaps. Some discussions are made on the colloidal structures of the dispersed systems aluminum soaps-hydrocarbon.
