摘要:
Crude oils having high pour points, mineral lubricating oils and fuel oils are improved in one or more of their characteristics such as their dispersancy, pour point, viscosity and viscosity index characteristics by the addition of a copolymer of (a) a monomeric aziridineethyl acrylate or methacrylate and (b) a monomeric alkyl ester of acrylic or methacrylic acid whose alkyl substituent contains 8 to 18 carbon atoms, said copolymer having a molecular weight of at least about 20,000 and a mole ratio of (a):(b) within the range of about 1:2 to about 1:99, respectively, e.g., aziridineethyl methacrylate:lauryl methacrylate (1:19).

1. A GREASE COMPOSITION COMPRISING A MAJOR PORTION OF A LUBRICATING OIL AND MINOR GREASE THICKENING PORTIONS OF (1) AN ALKALI OR ALKALINE EARTH METAL SALT OF A POLYUREA SULFONATE OR CARBOXYLATE COMPOUND HAVING AT LEAST 2 UREIDO GROUPS AND HAVING A MOLECULAR WEIGHT BETWEEN ABOUT 250 AND 2500 AND (2) AN ALKALINE EARTH METAL ALIPHATIC MONOCARBOXYLATE HAVING FROM 1 TO 3 CARBONS.
摘要:
KETO FATTY ACIDS OR DERIVATIVES OF KETO FATTY ACIDS ARE CYANOETHYLATED AND THE RESULTING THREE CARBON CYANOETHYL BRANCHED CHAIN FATTY ACIDS ARE MIXED WITH AN APPROPRIATE AMOUNT OF A DIESTER OR A PETROLEUM BASE OIL. THE MIXTURE IS THEN REACTED IN SITU WITH A DILUTE AQUEOUS SOLUTION OF LITHIUM HYDROXIDE TO BOTAIN A STABLE GREASE
摘要:
A GREASE COMPOSITION IS PROVIDED COMPRISING A MAJOR PORTION OF A MINERAL OIL OF LUBRICATING VISCOSITY AND EFFECTIVE AMOUNTS OF (1) AND ALKALI METAL OR ALKALINE EARTH METAL SOAP OF A FATTY ACID, (2) A N,N-DI(HYDROXY-LOWER ALKYL) SATURATED ALIHATIC CARBOXAMIDE AND (3) AT LEAST ONE ALKALI METAL SALT OF A MEDIUM-TO-LONG-CHAIN ALIPHATIC ORTHO- OR PYROROPHOSPHATE ESTER, METAL OR ALKALINE EARTH METAL SOAP IS A SOAP COMPLEX OF A MIXTURE OF A FATTY ACID AND A LOW MOLECULAR WEIGHT ALIPHATIC ACID. THE GREASES DESCRIBED HAVE SUPERIOR RUST INHIBITION PROPERTIES. THE GREASES ALSO RETAIN THEIR PENETRATION PROPERTIES WHEN CONTACTED WITH WATER AND HAVE SUPERIOR ADHESIVENESS QUALITIES.
