摘要:
Additives made by reaction of (A) at least one phosphorus acid compound of the formula:
wherein each X is independently oxygen or divalent sulfur, M is hydrogen or an equivalent of metal or ammonium cation, R is a hydrogen atom or a hydrocarbyl or hydrocarbyloxy or hydrocarbyl mercapto group of about one to about 30 carbon atoms and R'' is XM or R with the proviso that the total number of carbon atoms in both R and R'' is at least two, with (B) at least one sulfocontaining compound of the formula:
or
wherein y is one or two, R3 is hydrogen or lower alkyl group, R2 is a divalent or trivalent hydrocarbyl group, R4 is a trivalent hydrocarbyl group, and Q is -OH, -OR3, -OM, an alkylene polyamine residue, or N(R3)2, are novel and useful and have utility as, for example, additives for water-containing hydraulic fluids.

LUBRICATING AND FUEL COMPOSITIONS COMPRISING A MAJOR AMOUNT OF A LUBRICATING OIL AND A MINOR PROPORTION OF AN ESTER DERIVATIVE OF A HYDROCARBON-SUBSTITUTED SUCCINIC ACID WHEREIN THE HYDROCARBON SUBSTITUENT CONTAINS AT LEAST ABOUT FIFTY ALIPHATIC CARBON ATOMS, THE SUBSTITUENT BEING FURTHER CHARACTERIZED BY HAVING NO MORE THAN ABOUT 5% OLEFINIC LINKAGES THEREIN BASED ON THE TOTAL NUMBER OF CARBON-TO-CARBON COVALENT LINKAGES IN THE SUBSTITUENT. THE ESTERS INCLUDE THE ACIDIC ESTERS, DIESTERS, MIXED ESTER-METAL SALTS, AND MIXTURES OF THESE WHEREIN THE ESTER MOIETY IS DERIVED FROM MONOHYDRIC AND POLYHYDRIC ALCOHOLS, PHENOLS, NAPTHTHOLS, AND THE LIKE.
