Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
149 words
A LUBRICATING COMPOSITION COMPRISING A MAJOR PROPORTION OF A LUBRICATING OIL AND A MINOR PROPORTION OF A METAL COMPLEX PREPARED BY THE PROCESS COMPRISING FORMING A NON-ACIDIC, ACYLATED NITORGEN INTERMEDIATE BY THE REACTION OF 1 EQUIVALENT OF A HYDROCARBON-SUBSTITUTED SUCCINIC ACID OR ANHYDRIBE HAVING AT LEAST ABOUT 50 ALIPHATIC CARBON ATOMS IN THE HYDROCARBON SUBSTITUENT WITH FROM ABOUT 1 EQUIVALENT TO ABOUT 2 MOLES OF AN AMINE SELECTED FROM THE CLASS CONSISTING OF ALKYLENE AMINES, PIPERAZINES, AND IMIDAZOLINES AND REACTING SAID ACYLATED NITROGEN INTERMEDIATE WITH FROM ABOUT 0.1 EQUIVALENT TO ABOUT 2 EQUIVALENTS PER EQUIVALENT OF THE AMINE, OF A COMPLEX-FORMING METAL COMPOUND SELECTED FROM THE CLASS CONSISTING OF NITRATES, NITRITES, HALIDES, CARBOXYLATES, PHOSPHATES, PHOSPHITES, SULFATES, SULFITES, CARBONATES, BORATES, AND OXIDES OF CADMIUM, TIN, AND METALS HAVING ATOMIC NUMBERS FROM 24 TO 30 AT A TEMPERATURE ABOVE ABOUT 25* C. AND BELOW THE DECOMPOSITION POINT OF THE REACTION MIXTURE.
