    Abstract: A NOVEL SURFACTANT COMPOSITION IS PRODUCED BY REACTING ASPHALTENES WITH AN ANHYDRIDE OR HALIDE OF ONE OR MORE OF THE FOLLOWING DICARBOXYLIC ACIDS: MALEIC ACID, SUCCINIC ACID AND GLUTARIC ACID, WITH THE REACTION PRODUCT THEN BEING SEPARATED AND NEUTRALIZED WITH A WATER-SOLUBLE OXIDE OR HYDROXIDE OF A GROUP II-A METAL. THE SURFACTANT COMPOSITION FORMED IS USEFUL IN THE PREPARATION OF STABLE WATER-IN-OIL EMULSIONS AND ALSO FOR DISPERSING SOLID PARTICLES IN AN OILY MEDIUM.
