Abstract:
Various liquid and semisolid lubricant compositions are provided, in particular lubricant compositions containing oil from the seeds of the Brassicaceae Orychophragmus violaceus, preferably those that have been esterified with one or more fatty acids such as palmitoleic acid, oleic acid, linoleic acid, lauric acid, palmitic acid, stearic acid, or a combination thereof. In various aspects, lubricant compositions are provided that include a petroleum or a synthetic base oil and about 40% or less by weight of a liquid lubricant composition containing oil from the seeds of the Brassicaceae Orychophragmus violaceus, preferably those that have been esterified with one or more fatty acids. In various aspects, semisolid lubricant composition are provided containing an emulsion of (i) a thickener and (ii) an oil from the seeds of the Brassicaceae Orychophragmus violaceus, preferably those that have been esterified with one or more fatty acids.
Abstract:
Working fluids for a low global warming potential (GWP) refrigeration system comprising a compressor. The working fluid may comprise (a) a lubricating oil component comprising (i) at least one aromatic ester comprising the reaction product of an aromatic hydrocarbon having at least one carboxylic functional group and an (mono)alkylalcohol and/or glycol ether; and (b) a refrigerant.
Abstract:
A method for preventing or reducing engine knock or pre-ignition in a high compression spark ignition engine with relatively high oil consumption, lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition that contains a lubricating oil base stock comprising at least one ester including at least one group selected from the group consisting of Formula (1), Formula (2), Formula (3) and Formula (4) below or at least one ester having at least 25% of its carbons in the form of methyl groups: The lubricating oils of this disclosure are useful as passenger vehicle engine oil (PVEO) products.
Abstract:
La présente invention concerne des compositions, et plus particulièrement des compositions lubrifiantes, comportant un alternatif à l'adipate de di-isotridécyle (DITA). La présente invention divulgue donc des compositions comportant du succinate de di- (2-hexyldécyle), avantageusement d'origine renouvelable, ainsi que leurs utilisations en tant que compositions lubrifiantes, en particulier comme huiles hydrauliques ou huiles moteurs.
Abstract:
The presently claimed invention is directed to a method for reducing the friction coefficient of a lubricating oil composition in the lubrication of a mechanical device comprising formulating said lubricating oil composition with a carboxylic acid ester obtainable by reacting a mixture comprising at least on dicarboxylic acid and at least one branched C 10 alcohol.
Abstract:
The presently claimed invention is directed to the novel use of polyester obtainable by reacting a mixture comprising cyclohexane-1,2-dicarboxylic acid and an alcohol mixture comprising 1 - nonanol, monomethyloctanols, dimethylheptanols and monoethylheptanols and subsequent hydrogenation of said total mixture as lubricants and a lubricant composition comprising these polyesters.
