초록 ▼

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.

대표청구항 ▼

An oil-soluble dispersant composition having demulsifying characteristics which is the reaction product obtained by the reaction, at a reaction temperature in the range of about 25°C. to about 300°C., of a carboxylic acid acylating agent (A) having at least 30 aliphatic carbon atoms per molecule, with I. a hydroxy compound (B) sekected from the group consisting of polyhydric aliphatic alcohols and aromatic alcohols; II. a polyoxyalkylene polyamine (C) having an average molecular weight of at least about 200 and selected from the group consisting of those corresponding to the formula, H2N－Alkylene－(－O－Alkylene)m－NH2, and R－[－Alkylene－(－O－Alkylene)n－NH2]3-6, wherein m has a value of about 3 to about 70, n has a value of from about 1 to about 40 with the proviso that the sum of all the n\s is from about 3 to about 70, and R is a polyvalent saturated hydrocarbon radical of up to about 10 carbon atoms and has a valence of 3 to 6; and III. an alkylene amine (D); wherein both (B) and (C) are present in amounts of at least about 0.001 equivalent per equivalent of (A), and (D) is present in an amount ranging from zero to about 4 equivalents per equivalent of (A). An oil soluble dispersant composition having demulsifying characteristics which is the reaction product obtained by the reaction, at a reaction temperature in the range of 25°C. to 300°C., of a substantially saturated hydrocarbon substituted dicarboxylic acid acylating agent (A) in which the substitutents are derived from 1-olefin polymers or halogenated 1-olefin polymers, having an average molecular weight in the range of about 700 to 5000, with I. a polhydric aliphatic alcohol (B) haviing from 2 to 10 hydroxy groups per molecule; II. a polyoxyalkylene polyamine (C) having a molecular weight in the range of from about 200 to about 4000, and selected from the group consisting of those corresponding to the formula H2N－Alkylene－(－O－Alkylene)m－NH2, and R－[－Alkylene－(－O－Alkylene)n－NH2]3－6, wherein m has a value of about 3 to about 70, n has a value of from about 1 to about 40 with the proviso that the sum of all the n\s is from about 3 to about 70, and R is a polyvalent saturated hydrocarbon radical of up to about 10 carbon atoms and has a valence of 3 to 6; and (III) an alkylene amine (D); wherein both (B) and (D) are present in amounts ranging from about 0.01 to about 4 equivalents per equivalent of (A), and (C) is present in an amount ranging from about 0.01 to about 2.0 equivalents per equivalent of (A).
