Abstract

PURPOSE: A dispersant for coal/oil mixed fuels, comprising a dialkyl sulfosuccinate ester and a specific nonionic surfactant.
CONSTITUTION: As the nonionic surfactant, there is employed a polymer, MW of 2,000W45,000, polyoxyethylene group content of about 30W90wt%, prepared by adding to 1mol of an aromatic hydroxy compound such as an alkylphenol or bisphenol A, 20W800mol of ethylene oxide and 15W200mol of propylene oxide to form blocks. Namely, (a) a metal salt of dialkyl sulfosuccinate such as sodium dibutyl sulfosuccinate, represented by the formula, wherein R1 and R2 are alkyls of at least 4C; M is an n-valent metal and n is an integer of 1W3, is mixed with (b) the above surfactant, so as to provide a weight ratio of 1/9W9/1. Then, about 0.01W1wt% of the resulting mixture is added to a fuel oil.
