Abstract
There is provided a fluid composition including at least one hydroxy-substituted carboxylic acid. Also provided are methods of inhibiting at least one of corrosion and rust and of improving at least one of lubricity and lead compatibility. Also provided are lubricating, fuel, anticorrosion, antirust, and additive concentration compositions.
Claims21
A transmission fluid composition comprising a transmission base fluid and at least one hydroxyl-substituted carboxylic acid selected from the group consisting of hydroxycinnamic acid, 3-(4-hydroxyphenyl)propionic acid, 2-hydroxycinnamic acid, and 3-(2-hydroxyphenyl)propionic acid.
A lubricant composition comprising a transmission base fluid and at least one hydroxy-substituted carboxylic acid selected from the group consisting of hydroxycinnamic acid, 3-(4-hydroxyphenyl)propionic acid, 2-hydroxycinnamic acid, and 3-(2-hydroxyphenyl)propionic acid.
A method for inhibiting corrosion of machinery comprising providing a fluid composition comprising a transmission base fluid and at least one hydroxy-substituted carboxylic acid to machinery, wherein the at least one hydroxy-substituted carboxylic acid is selected from the group consisting of hydroxycinnamic acid, 3-(4-hydroxyphenyl)propionic acid, 2-hydroxycinnamic acid, and 3-(2-hydroxyphenyl)propionic acid.
A method for inhibiting rust of machinery, comprising providing a fluid composition comprising a transmission base fluid and at least one hydroxy-substituted carboxylic acid to machinery, wherein the at least one hydroxy-substituted carboxylic acid is selected from the group consisting of hydroxycinnamic acid, 3-(4-hydroxyphenyl)propionic acid, 2-hydroxycinnamic acid, and 3-(2-hydroxyphenyl)propionic acid.
A lubricating oil composition comprising a major amount of a transmission base fluid and oil and a minor amount of a composition comprising at least one hydroxy-substituted carboxylic acid selected from the group consisting of hydroxycinnamic acid, 3-(4-hydroxyphenyl)propionic acid, 2-hydroxycinnamic acid, and 3-(2-hydroxyphenyl)propionic acid.
An additive concentrate composition comprising a solvent or diluent, and at least one hydroxyl-substituted carboxylic acid selected from the group consisting of hydroxycinnamic acid, 3-(4-hydroxyphenyl)propionic acid, 2-hydroxycinnamic acid, and 3-(2-hydroxyphenyl)propionic acid.
