The present invention provides a water-soluble dispersant for aqueous slurries of coal, lignite, cement, gypsum, and fillers. The dispersant comprises a sulfonated mixture of polynuclear fused-ring aromatic hydrocarbon compounds. The mixture, prior to sulfonation, (a) is liquid at a temperature of 100.degree. Centigrade, (b) has an aromatic content of more than about sixty percent, (c) a molecular weight distribution of from about 150 to about 10,000, and (d) a weight average molecular weight of less than about five hundred.
