Abstract

Amides prepared from mono- or poly hydroxy-substituted aliphatic monocarboxylic acids and primary or secondary amines which are useful as friction reducing agents.

Claims

1. A lubricant composition comprising a major amount of an oil of lubricating viscosity and a minor effective friction-reducing amount of a reaction product formed by reacting equimolar amounts of an amine represented by the forming RR'"'"'NH wherein R is an aliphatic-based hydrocarbyl radical of about 10 to about 30 carbon atoms and R'"'"' is hydrogen or an alkyl group having 12 to 18 carbon atoms, with a hydroxy-substituted aliphatic monocarboxylic acid selected from the group consisting of glycolic, lactic, and 2,2 bis-(hydroxymethyl)propionic acid, said reaction being conducted at a temperature ranging from about 60°

to 180°

C.

2. A lubricant composition according to claim 1 containing from about 0.001 to about 5.0 weight percent of said reaction product.

3. A lubricant composition according to claim 1 in which said reaction product is prepared from oleyl amine and glycolic acid.

4. A lubricant composition according to claim 1 in which said reaction product is prepared from bis-dodecyl amine and glycolic acid.

5. A lubricant composition according to claim 1 in which said reaction product is prepared from oleyl amine and lactic acid.

6. A lubricant composition according to claim 1 in which said reaction product is prepared from oleyl amine and 2,2-bis(hydroxymethyl)propionic acid.
