Abstract
A method for making a titanium-containing lubricant additive, a lubricant additive concentrate made by the method and a lubricating composition containing the additive concentrate. The method includes reacting titanium alkoxide with water in a reaction medium that includes a dispersant to provide a homogeneous titanium-containing additive product. The additive product made by the method is substantially devoid of acidic components.
Claims20
A method for making a titanium-containing, lubricant additive comprising reacting titanium alkoxide with water in the presence of an organic dispersant selected from the group consisting of hydrocarbyl succinimides, hydrocarbyl amines, and Mannich base dispersants and an alkanol to provide a homogeneous titanium-oxide additive product, wherein additive product is substantially devoid of acidic characteristics.
A titanium additive product for a lubricating oil comprising a titanium product made by a process comprising reacting titanium alkoxide with water in the presence of an organic dispersant selected from the group consisting of hydrocarbyl succinimides, hydrocarbyl amines, and Mannich base dispersants and an alkanol at a temperature ranging from about 25° to about 140° C. to provide a homogeneous titanium-oxide additive product, wherein additive product in a base oil is no more corrosive than the base oil devoid of the additive product as determined by a high temperature corrosion bench test.
