The surfactants from petroleum colloids were characterized. The crude oils, means of dispersion, petroleum colloids and their fractions are mixtures of several surfactants. The surface tension depends on the pH. The stability of the emulsions does not depend directly on the surface tension, but depends on the composition and concentration of the fractions, on the viscosity of the oil phase depending on temperature and on the time. Crude oil rich in paraffin and its petroleum resin stabilize emulsions better than crude oils rich in aromatics and asphalt and their colloids. (EF)Die grenzflaechenaktiven Stoffe aus Erdoelkolloiden wurden charakterisiert. Die Rohoele, Dispersionsmittel, Erdoelkolloide und deren Fraktionen sind Mischungen aus meh...
