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 resulting from the copolymerization of ethylene oxide with propylene oxide.
CONSTITUTION: There is provided a dispersant which is used for the production of mixed fuel of finely divided coal powder and a fuel oil and excels in fluidity, mechanical stability and static stability over a long period of time, containing a dialkyl ester metal salt of sulfosuccinic acid of formula I (wherein R1, R2 are alkyl having at least 4 carbon atoms; P is 1, 2, 3; M is p-valent metal) and a nonionic surfactant having an average MW of 2,000W45,000, of formula II (wherein R3, R4 are H, 1W 6C alkyl; l+n is 20W800 in moles of the addition of ethylene oxide; m is 15W200 in moles of the addition of propylene).
