L-2351R Title: PHOSPHORUS- AND/OR NITROGEN-CONTAINING DERIVA TIVES OF SULFUR-CONTAINING COMPOUNDS, LUBRICANT, FUEL AND FUNCTIONAL FLUID COMPOSITIONS This invention is directed to phosphorusand/or nitrogen-containing derivative compositions useful particularly in fuels, and in lubricating and functional fluid compositions. The derivative compositions comprise a phosphorus- and/or nitrogen-con-taining derivative composition of sulfur-containing compounds prepared by the process comprising reacting (A) at least one sulfur composition from the group of (A-1) compounds 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?N, R5-C=NR6, CON(R)2, or NO2, and G1 may be CH2OH, wherein X is O or S, each of R and R5 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; and (A-2) compositions prepared by reacting sulfur and/or sulfur halides with compounds represented by the structural formulae (II) (III) wherein each of R7 is independently H or a hydrocarbyl group; R8 is H, a hydrocarbyl group, or a hydrocarbyloxy group; G3 is C(X)R, C?N, COOR, CON(R)2, NO2 or R5C=NR6 wherein X, R, R5 and R6 are as defined above,; and y is an integer from zero to 5; with (B) a di- or trihydrocarbyl phosphite, at least one amine compound containing at least one NH or NH2 group, or a combination of said phosphite and amine, provided, however, when G1 and G2 in (A-l) are -C(X)R, (B) is a di- or tri-hydrocarbylphosphite or a mixture of said phosphite and an amine compound containing at least one NH or NH2 group. The compositions of the invention also may include (C) at least one carboxylic dispersant composition prepared by the reaction of a hydrocarbonsubstituted succinic acid-producing compound with at least about one-half equivalent, per equivalent of acid-producing compound, of an organic hydroxy compound or amine containing at least one hydrogen attached to a nitrogen atom, or a mixture of said hydroxy compound and amine. The lubricating compositions of the present invention are particularly useful as lubricating oils, functional fluids and greases. The invention also relates to fuels and aqueous systems containing the above-described derivative compositions. |
