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 reaction of a specified polyalkylene glycol with a diisocyanate.
CONSTITUTION: There is provided a dispersant which is used for the production of a 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 the formula (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 at least two urethane linkages per molecule, a polyoxyethylene gp. content of 30W90wt% and a polyoxypropylene gp. content of 15W50wt%, which is a reaction product resulting from the reaction of a diisocyanate cpd. with a polyalkylene glycol including a polyethylene glycol having an average MW of 200W 20,000 and a polypropylene glycol having an average MW of 200W20,000.
