Stabilized Blends Containing Friction Modifiers

a technology of friction modifiers and stabilized blends, which is applied in the preparation of carboxylic compounds, fuels, organic chemistry, etc., can solve the problems of limited use of many friction modifiers, composition hazy or cloudy, and limit the choice of additive treatment levels and available treatment levels, so as to improve solubility and/or compatibility and/or stability

Problems solved by technology

However, many friction modifiers may only be used in limited ways due to solubility and/or compatibility issues with the functional fluids in which they are used.
These friction modifiers, when used at levels above their solubility and/or compatibility limits, may fall out of the functional fluid composition over time and/or cause the composition to appear hazy or cloudy.
These are serious issues in the manufacturing and blending processes of the fluids as well as in the field.
This stringent standard greatly limits the choices of and available treatment levels for many additives, including the friction modifiers discussed herein.
These friction modifiers could provide improved performance to a functional fluid but not widely used and/or are not used at the optimal level because the additive does not meet the ...

[0195]A set of samples is prepared by adding a specific friction modifier to specific mediums where the friction modifier is known to have compatibility issues in such compositions. The friction modifier used in this testing is a dialkyl hydrogen phosphonate (FM-1). The mediums used in this testing include: a Group I base oil hydraulic fluid (MEDIUM-1), a Group IV base oil hydraulic fluid (MEDIUM-2), and a Group I base oil industrial gear oil fluid (MEDIUM-3). The compatibilizers used in this testing include: a quaternary ammonium salt derived from a 1000 number average molecular weight polyisobutylene derived succinic anhydride and a polyalkylene polyamine, quaternized using an alkylene epoxide in combination with an acid where the compounds has a hydrogen-donating group within two bonds of two hydrogen-accepting groups and a second hydrogen-donating group separated by one bond from a hydrogen-accepting group (COMPAT-1), a low molecular weight acylated nitrogen compound that includ...

Abstract

The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and/or limited compatibility with the functional fluids with which they are used. In particular the present invention deals with functional fluids used in internal combustion engines, such as engine oils, and phosphorus-containing friction modifiers, where the friction modifier is present in the functional fluid composition at levels that would otherwise cause the composition to be unstable and/or hazy.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to functional fluid compositions containing friction modifiers, and specifically stable compositions containing friction modifiers with limited solubility in and / or limited compatibility with the functional fluids with which they are used.[0002]Friction modifiers and their importance to various types of functional fluids are known. However, many friction modifiers may only be used in limited ways due to solubility and / or compatibility issues with the functional fluids in which they are used. Many friction modifiers, and specifically those derived from hydroxy-carboxylic acids, have limited solubility in functional fluids, such as engine oils and gear oils. These friction modifiers, when used at levels above their solubility and / or compatibility limits, may fall out of the functional fluid composition over time and / or cause the composition to appear hazy or cloudy.[0003]These are serious issues in the manufacturing and bl...
