ABSTRACT:
This invention is directed to an oil soluble dispersant and to a process for preparing said dispersant which comprises contacting and reacting at least one carboxylic-acylating agent having at least about 30 aliphatic carbon atoms per molecule with effective amounts of at least one hydroxy compound, at least one polyoxyalkylene polyamine having an average molecular weight of at least about 200 and from zero to about 4.0 equivalents of at least one alkylene amine per equivalent of said carboxylic-acylating agent. The dispersant of this invention is particularly useful as an additive for a variety of oleaginous materials including, for example, fuels, lubricating oils, hydraulic fluids and the like.
