Abstract

The study of emulsions and emulsification is of very great theoretical and practical interest. From the standpoint of pure science it throws much light on the problems of surface tension, surface concentration, absorption, surface films, electrical double layers. Brownian movement, and the general theory of disperse systems and colloids. It is also of importance in biological science, e.g., the adsorption of fats and the permeability of membranes. When industrial and applied science are considered, it is remarkable how many subjects of interest and importance are dependent on a knowledge of the formation, behavior, and stability of emulsions. In this connection, one has only to think of milk, butter. margarine, the emulsions and ointments of pharmacy, emulsified disinfectants and lubricants, rubber latex, spraying fluids, soaps and other detergents, flotation processes, and a host of other things in order to realize the extremely important role of emulsions in practical life. The engineer who wants to prevent emulsification of his lubricating oil, or to remove oil from his condensed water, is dependent on the physical chemistry of emulsions for the methods which he employs. The object of this research on the emulsification of water in gasoline was to study the effect of various metallic soaps on the amount of water that an emulsion might contain. Very little has been done on the quantitative determination of water in water-in-oil emulsions as those emulsions are of the least commercial and industrial importance.
