Document Type and Number:
Japanese Patent JPH01501234
Kind Code:
A
Abstract:
This invention is directed to lubricating and functional fluid compositions having improved antioxidant and extreme pressure properties and high temperature stability. The lubricant and functional fluid compositions comprise a major amount of at least one oil of lubricating viscosity and a minor amount of (A) a sulfur compound characterized by the structural formula (I) wherein R1, R2, R3 and R4 are each independently H or hydrocarbyl groups; R1 and/or R3 may be G1 or G2; R1 and R2 and/or R3 and R4 together may be alkylene groups containing about 4 to about 7 carbon atoms; G1 and G2 are each independently C(X)R, COOR, C 3BOND N, R5-C=NR6, CON(R)2 or NO2, and G1 also ay be a CH2OH group, wherein X is O or S, R5 and each R are independently H or a hydrocarbyl group, R6 is H or a hydrocarbyl group; when both G1 and G2 are R5C=NR6, the two R6 groups together may be a hydrocarbylene group linking the two nitrogen atoms; when G1 is CH2OH and G2 is COOR, a lactone may be formed by intramolecular combination of G1 and G2; and x is an integer from 1 to about 8; provided that when both G1 and G2 are C(O)R groups and R1 and R3 are H or hydrocarbyl groups, at least one R is a hydrocarbyl group. The lubricating compositions of the present invention are particularly useful as lubricating oils, functional fluids and greases. The invention also relates to aqueous systems containing the above-described sulfur compounds represented by Formula I.
