Abstract

PURPOSE: To provide a dispersant for a mixed fuel of finely divided coal powder and a fuel oil, containing a dialkyl ester metal salt of sulfosuccinic acid and a nonionic surfactant obtd. by the addition of ethylene oxide and propylene oxide to an amino cpd.
CONSTITUTION: There is provided the desired dispersant which excels in long-term stability and fluidity, containing a dialkyl ester metal salt of sulfosuccinic acid of formula I (wherein R, R' are alkyl having at least 4 carbon atoms; n is 1,2,3; M is n-valent metal) and a nonionic surfactant having an average MW of 2,000W 45,000, obtd. by the addition of 20W800mol of ethylene oxide and 15W200mol of propylene oxide in block form to one mole of an amino cpd. having 1W3 nitrogen atoms per molecule, pref. an amino cpd. of formula II or III (wherein R1, R2 are H, 1W18C alkyl, alkenyl, aryl, 2-hydroxyethyl; R3 is H, 2-hydroxyethyl; R4, R5, R8, R9, R10 are H, 2-hydroxyethyl; R6, R7 is 2W4C alkylene; m is 0,1).
