Abstract
The invention provides compositions comprising at least one alkylphenol resin (constituent I) and, based on the alkylphenol resin, from 0.05 to 10% by weight of at least one salt of an aromatic base and of a sulfonic acid (constituent II).
Claims16
A composition comprising at least one alkylphenol-aldehyde resin (constituent I) and, based on the alkylphenol-aldehyde resin, from 0.05 to 10% by weight of at least one salt (constituent II), wherein the at least one salt is formed from an aromatic base and a sulfonic acid, wherein the aromatic base is an oil-soluble compound containing a cyclic, through-conjugated hydrocarbon skeleton with 4n+2π electrons and at least one heteroatom capable of salt formation, and wherein the heteroatom capable of salt formation is part of the aromatic ring system.
A method for improving the cold flowability of a mineral oil distillate having a sulfur content less than 350 ppm, wherein the method comprises the step of adding to said mineral oil distillate a composition comprising at least one alkylphenol-aldehyde resin (constituent I) and, based on the alkylphenol-aldehyde resin, from 0.05 to 10% by weight of at least one salt (constituent II), wherein the at least one salt is formed from an aromatic base and a sulfonic acid, to provide said mineral oil distillate with improved cold flowability, wherein the aromatic base is an oil-soluble compound containing a cyclic, through-conjugated hydrocarbon skeleton with 4n+2π electrons and at least one heteroatom capable of salt formation, and wherein the heteroatom capable of salt formation is part of the aromatic ring system.
