Abstract
PURPOSE: To provide dispersion stabilizer which is used for a mixt. of coal and oil and has an excellent effect even at low concentration, consisting of a specified fluorine-contg. surfactant.
CONSTITUTION: A fluorine-contg. surfactant in which part of hydophobic gp. contains (a) perfluoroalkyl gp. (e.g. perfluoroalkyl sulfonate), (b) perfluoroalkenyl gp. (e.g. perfluoroalkenyloxybenzene sulfonate, polyoxyethylene perfluoroalkenyloxybenzoate) or (c) ω-H-perfluoroalkyl gp. (e.g. telomerized cpd. of tetrafluoroethylene and methanol) is used as dispersion stabilizer for a mixt. of coal and oil which is a colloidal fuel obtd. by dispersing finely divided coal particle in hydrocarbon fuel oil. The dispersion stabilizer is used in an amount of pref. 0.01W0.1wt% based on the weight of the mixt. of coal and oil.
