The present invention is directed to methods of producing reduced viscosity oleaginous compositions containing Group I-B, II-A and II-B metal, particularly copper and/or zinc, salts of the product of a polyolefin having a number average molecular weight (Mn) of at least 600 which has been substituted with at least one dicarboxylic acid producing moiety per polyolefin molecule, wherein the metal salt product is contacted with lower aliphatic or cycloaliphatic amines having from 1 to 4 nitrogen atoms per molecule. The compositions of the present invention can also provide increased stability to viscosity growth, e.g. during storage of the materials prepared by the process of this invention. The resulting solutions are useful in lubricating oils as additives, e.g., as antioxidant lube oil additives.

The invention herein is concerned with new compositions of matter made by (1) reacting phosphorus pentasulfide with an amide and (2) reacting this product with a nitrogen-containing compound, and lubricant compositions containing same. The compositions reduce friction to a greater extent than lubricants containing no additive and, when placed in lubricating oils and used in an internal combustion engine, fuel consumption is reduced.

The invention comprises the product obtained by heating a sulphurized terpene or a mixture of sulphurized terpenes, formed by reacting a terpene or a mixture of terpenes and sulphur, with elemental phosphorus, e.g. red phosphorus. The terpene may be a monocyclic terpene-preferably commercial dipentene-or a dicyclic terpene, e.g. alphapinene. The sulphurized terpene may be prepared by heating the terpene with an amount ranging from 1.5 to 2 atoms of elemental sulphur per mol. of terpene, e.g. at a temperature of 135 DEG to 200 DEG C. The sulphurization step is preferably carried out in the presence of a rubber vulcanization inhibitor, e.g. tetramethyl thiuram disulphide, a mercapto-benzthiazole or diphenyl guanidine. The sulphurized terpene product is preferably stripped of its more volatile portions by steam distillation either prior to or after heating with elemental phosphorus. The amount of phorphorus used may vary between 1 and 10 per cent by weight based on the weight of sulphurized terpene. A suitable temperature for reaction with the phosphorus is 110 DEG to 200 DEG C., preferably 125 DEG to 175 DEG C., and the heating may be for a period from 1 to 8 hours particularly 2 to 5 hours. The final product can be purified by dissolving it in a suitable volatile solvent, removing unreacted phosphorus by filtration and then recovering the product from the solvent, e.g. by vacuum distillation. In the examples sulphurized dipentene is reacted with phosphorus. Specification 688,293 is referred to.ALSO:A composition containing a lubricating oil and a minor proportion of the product obtained by heating a sulphurized terpene or a mixture of sulphurized terpenes formed by reacting a terpene or a mixture of terpenes and sulphur, with elemental phosphorus. The amount of product used is preferably less than 5 per cent and particularly less than 1 per cent based on the weight of lubricating oil. The terpene may be a monocyclic terpene-preferably commercial dipentene or a dicyclic terpene, e.g. alphapinene. Suitable lubricating oils are mineral oils or synthetic ester type oils, e.g. adipates or sebacates of alcohols in the C7 to C10 range or esters prepared from glycols or polyglycols, aliphatic dibasic acids and monohydric alcohols or monobasic acids as chain terminators. In the examples compositions are prepared by adding the product obtained by heating sulphurized dipentene with phosphorus to a synthetic type of aviation lubricant and to mineral oil which may also contain the barium salt of p-iso-octyl phenol sulphide and calcium mahogany sulphonates. Specification 688,293 is referred to.

C5-C9 lactone based adduct materials are made by reacting a C5-C9 lactone with a polyamine, a polyol or an amino alcohol to form a lactone adduct intermediate, and thereafter reacting the intermediate with an aliphatic hydrocarbyl saturated or unsaturated, straight chain or branched chain monocarboxylic or dicarboxylic acylating agent having from about one to about 165 total carbon atoms in said straight or branched chain to insure that the resulting lactone adduct is hydrocarbon soluble. The resulting adduct material are useful per se, as oil soluble dispersant additives, and are useful in fuel and lubricating oil compositions including concentrates containing the additives.
