Abstract:
SYNTHETIC LUBRICATING OIL COMPOSITION COMPRISING A MAJOR PORTION OF AN ALIPHATIC ESTER BASE OIL HAVING LUBRICATING PROPERTIES FORMED BY THE REACTION OF A PENTAEYTHRITOL OR TRIMETHYLOLPRAPANE AND AN ORGANIC MONOCARBOXYLIC ACID CONTAINING FROM ABOUT 0.01 TO 2.5 WEIGHT PERCENT OF AN AMMONIUM THIOCYANATE REPRESENTED BY THE FORMULA:
R$R''R"R"''$CN
IN WHICH R IS A HYDROCARBYL OR AMINO-SUBSTITUTED HYDROCARBYL GROUP HAVING FROM 1 TO 30 CARBON ATOMS OR A RADICAL HAVING THE FORMULA:
R-N(+)(-R'')(-R")-R''" (-)S-CN
IN WHICH R"" IS A BRIDGING POLYMETHYLENE RADICAL HAVING FROM 2 TO 4 CARBON ATOMS, AND R'', R" AND R"'' REPRESENT HYDROGEN OR A HYDROCARBYL GROUP HAVING FROM 1 TO 30 CARBON ATOMS, AND FROM ABOUT 0.04 TI 2 WEIGHT PERCENT OF A POLYHYDROXY-SUBSTITUTED ANTHRAQUINONE REPRESENTED BY THE FORMULA:
-R""-N(-R'')(-R''")-R"-S-CN
IN WHICH X, Y AND Z EACH REPRESENT HYDROGEN OR A HYDROXYL GROUP AND AT LEAST ONE OF THE THESE IS A HYDROXYL GROUP.
