摘要:
Disclosed are beta-amino acid derivatives which impart friction reducing properties to lubricating compositions. The additives of the invention are bifunctional carboxylic acid salts and amides derived from the basic hydrolysis of a cyanoethylated amine.
摘要:
Amides prepared from mono- or poly hydroxy-substituted aliphatic monocarboxylic acids and primary or secondary amines which are useful as friction reducing agents.
摘要:
Citric imide acids represented by the formula: ##STR1## are disclosed, wherein R is a hydrocarbon-based radical having up to 30 carbon atoms. The disclosed citric imide acids are useful as additives in lubricants, especially as friction reducing agents in motor oils and other lubricants.
