Abstract: Provided is a cold storage medium according to the present invention contains tetra-n-butylammonium ions, silver ions, at least one kind of halide ions selected from the group consisting of fluoride ions, chloride ions, and bromide ions, water, and at least one kind of carboxylic acid ions each represented by the following chemical formula R—COO? (where R represents a hydrocarbon group).
Abstract: The present invention relates to the use of ester group-including polymers having at least one nonpolar segment P and at least one polar segment D, where the polar segment D includes at least 8 repeating units, and the proportion of dispersing repeating units in the polar segment D is at least 30% by weight based on the weight of the polar segment D, as antifatigue additive in lubricants.

Abstract: A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.
Abstract: A lubricating base oil includes at least one of ionic liquids containing a compound represented by a formula (1): Z+A?, in which Z+ represents a cation and A? represents an anion, in which Z+ is a cyclic quaternary ammonium ion having two different side chains and A? is a conjugated amide ion.
Abstract: Morpholine derivatives useful as ashless TBN sources for lubricating oil compositions that are compatible with fluoroelastomeric engine seal materials, and lubricating oil compositions containing such compounds.
