Spontaneous emulsification of a pure liquid can occur. This is demonstrated when liquid hydrocarbons are quietly placed upon the surface of the solution of a suitable detergent. Here special attention has been given to xylene placed upon moderately dilute solutions of dodecylamine hydrochloride. In many cases violent disruption of the pure liquid occurs, when it is quietly placed upon a soap or detergent solution. Examination shows that the emulsitied droplets still consist of pure solvent stabilized by a coating of adsorbed protective colloid. The source of the required energy is the energy of adsorption, as well as solubilization of hydrocarbon in the aqueous detergent. The emulsion formed consists of spherical droplets which therefore retain a positive interfacial tension.
