摘要： A refrigerator oil composition may effectively suppress an increase in an acid value even when a ratio of an unsaturated fluorinated hydrocarbon compound (HFO) in a refrigerant is increased. Such a refrigerator oil composition can used for a refrigerant and may include one or more unsaturated fluorinated hydrocarbon compounds of formula (1):


CxFyH  (1),

wherein x is an integer of 2 to 6, y is an integer of 1 to 11, and z is an integer of 1 to 11, and one or more carbon-carbon unsaturated bonds are present in the molecule. The refrigerator oil composition may include a base oil (A), and one or more silicone compounds (B) selected from the group consisting of an unmodified silicone (B1) and a modified silicone (B2), wherein a content of the silicone compound (B) is 0.05% by mass or more based on the total amount of the refrigerator oil composition.

摘要： The present invention provides a lubricant composition comprising a base oil of lubricating viscosity, wherein the base oil comprises an ether base stock of formula (A), where: Ra and Rb are aliphatic hydrocarbyl groups and may be the same or different; the lubricant composition further comprising at least one aminic anti-oxidant and at least one phenolic anti-oxidant. In some embodiments, the ether base stock has the formula (1), where: R1 R2, R3, R4, R5 and R6 are as defined herein. The lubricant composition may be used for lubricating a surface in an internal combustion engine as well as for improving the fuel economy performance and/or piston cleanliness performance of an engine and/or a vehicle, such as an automotive vehicle associated with an internal combustion engine.

摘要： A method for improving low temperature performance of a lubricant in a compression-ignited internal combustion engine is disclosed. The method comprises operating the engine with a monograde lubricating oil composition comprising (a) a major amount of a base oil of lubricating viscosity; and (b) a minor amount of an overbased alkaline earth metal salt of an alkyl-substituted hydroxyaromatic compound, the alkyl substituent being a residue derived from an isomerized alpha-olefin having from 12 to 40 carbon atoms per molecule.

摘要： Provided is a vacuum pump oil which contains a mineral oil (A) having a temperature gradient Δ|η*| of complex viscosity between two points of t(° C.) and t−10(° C.) (where −15≤t≤−10), as measured using a rotary rheometer at an angular velocity of 6.3 rad/s, of 10 Pa·s/° C. or less, and one or more compounds selected from a phenol-based compound (B) and an amine-based compound (C), and which has a viscosity index of less than 160. The vacuum pump oil has a good ultimate vacuum degree and is excellent in water separability, oxidation stability and shear stability, and is therefore applicable to various applications.
