Abstract
PURPOSE: To provide title stabilizer which is used as dispersion stabilizer when finely divided coal particle is dispersed in a fuel oil, consisting of a specified nonionic surfactant.
CONSTITUTION: One mole of an amino cpd. having 1W3 -N< gp. of formula I or II (wherein R1, R2 are H, 1W18C alkyl, alkenyl, aryl, 2-hydroxyethyl; R3W5W R8W10 are H, 2-hydroxyethyl, R6, R7 are 2W4C alkylene; n is 0,1) is reacted with 20W800mol of ethylene oxide and 15W200mol of propylene oxide to obtain a nonionic surfactant having an average MW of 2,000W45,000 and polyoxyethylene gp. content of 30W90wt% in the molecule. Then 0.01W1.0wt% of the produced nonionic surfactant as a dispersion stabilizer is added to a mixed fuel consisting of 20W 70wt% of finely divided coal particle and 80W30wt% of a fuel oil.
