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 aliphatic polyhydric (at least pentahydric) alcohol or a saccharide such as xylitol or glycose, 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 1/9W 9/1. Then, about 0.01W1wt% of the resulting mixture is added to a fuel oil.
