Also provided are lubricating oil compositions containing the diraromatic amine derivatives.

Abstract: Diaromatic amine compounds or an isomer or isomeric mixture thereof is provided having the general formula: wherein n, m, R, R1, R2, R3, R4 and R5 are as defined herein are provided. Lubricating oil compositions and stabilizer-containing compositions containing the diaromatic amine compounds are also provided.

Abstract: Disclosed herein is composition comprising: (A) a lubricant or a hydrocarbon fuel; (B) at least one additive that is a 2-(S(N)-mercaptobenzothiazole)succinic or methylene succinate esters of a structure defined herein; and optionally {circle around (C)}) at least one zinc dihydrocarbyldithiophosphate.

Abstract: A composition of matter is disclosed wherein the composition comprises a hydrazide compound of the formula: wherein: R1 is selected from the group consisting of alkyl, alkyl ether, and phenyl; R2, R3, R4, R5, and R6 are independently selected from the group consisting of hydrogen, alkyl, alkyl ether, and aryl; and n is an integer of from 0 to 10; and wherein: when R1 is phenyl, it is of the structure: wherein R7, R8, and R9 are independently selected from the group consisting of hydrogen, alkyl, alkyl ether, and aryl, or R7 can be combined with R8 to form a ring of 5 or 6 carbon atoms. The hydrazides are useful as stabilizers for lubricants, greases, and polymeric systems, particularly lubricating oils, as are maleated polymers that have been functionalized with them.

Abstract: Disclosed herein is a composition comprising: A) a lubricant; and B) a mixture of antioxidants, wherein said mixture is prepared by the partial condensation of an alkylated diphenylamine with an aldehyde or ketone in the presence of an acidic catalyst to yield at least one acridan of the general formula: wherein: R1, R2, R3, and R4 are independently selected from the group consisting of hydrogen, C3 to C32 alkyl, and C3 to C32 alkenyl, provided that at least one of R1, R2, R3, and R4 is not hydrogen, and R5 and R6 are independently selected from the group consisting of C1 to C20 hydrocarbyl and hydrogen; wherein, at the termination of said condensation, residual alkylated diphenylamine is not separated from the acridan product.

Abstract: Dithiocarbamate derivative compounds, useful as multifunctional additives for lubricating oils and fuels, are provided and are derived from a reaction product obtained from (a) a di(hydrocarbyl)thiocarbamate intermediate derived from the reaction of a dihydrocarbylamine and carbon disulfide; (b) an amide of the general formula R7CONH2 wherein R7 is an alkylene group having 2 to about 30 carbon atoms; and (c) an effective amount of a carbonyl-containing compound.

Abstract: Apparatus includes a mounting member having a bore which closely receives the shaft and a counterbore in which two elastic O-rings separated by an annular element are received. A first compression member threadably engages the mounting member to apply axial pressure to the O-rings, which are radially compressed against the shaft by bevelled annular surfaces which capture the O-rings. This provides an environmental seal effective for a vacuum while still permitting axial and rotational movement of the shaft. Apparatus further includes a ball member fixed to the mounting member and received against an O-ring in a socket member. A second compression member threadably engaging the socket member to urge the ball member against the seal to provide additional sealing while permitting pivotal movement of the shaft.
