Traction fluids comprising Formula I, II, III, IV, V, VI, VII or a mixture thereof in combination with a base stock, a viscosity modifier, an anti-foaming agent, and an additive package.

The lubricating oil composition for a refrigerator of the present invention is a lubricating oil composition for a refrigerator that is used in combination with a refrigerant containing at least one fluorine-containing organic compound selected from compounds represented by the following molecular formula (A):

C.sub.pF.sub.rR.sub.s  (A)

wherein R represents Cl, Br, I, or H; p represents an integer of from 2 to 6; r represents an integer of from 1 to 12; and s represents an integer of from 0 to 11, provided that the molecule contains at least one carbon-carbon unsaturated bond, and the lubricating oil composition for a refrigerator contains a base oil and a cyclic organic compound having a cyclic hydrocarbon structure and having one or more non-conjugated double bond in a cyclic structure or a side chain thereof.

The present disclosure generally relates to the production of fuels, gasoline additives, and/or lubricants, and precursors thereof. The compounds used to produce the fuels, gasoline additives, and/or lubricants, and precursors thereof may be derived from biomass. The fuels, gasoline additives, and/or lubricants, and precursors thereof may be produced by a combination of intermolecular and/or intramolecular aldol condensation reactions, Guerbet reactions, hydrogenation reactions, and/or oligomerization reactions.

This method for producing a lubricating oil composition includes: a step of dissolving fullerenes in a base oil mainly composed of a multiply alkylated cyclopentane oil or an ionic liquid containing an imide as a negative ion to obtain a fullerene solution; and a step of producing fullerenes adduct by subjecting the above-described fullerene solution to a heat treatment in a non-oxidizing atmosphere.

To provide a lubricating oil composition achieving both of high traction coefficient and excellent low temperature fluidity at a higher level and having a high flash point, which contains a naphthene-based synthetic oil (A) having a flash point of 140° C. or higher, a longifolene (B), and a predetermined monoester-based synthetic oil (C), a method for producing the lubricating oil composition, and a continuously variable transmission using the lubricating oil composition.

The present invention relates to compositions comprising at least one fluoroolefin, HFC-32, and an effective amount of at least one inhibitor. The stabilized compositions may be useful in cooling and heating apparatus, such as refrigeration, air-conditioning, chillers, and heat pumps, as well as in applications as foam blowing agents, solvents, aerosol propellants, fire extinguishants, and sterilants.

Provided are: a lubricant base oil capable of achieving both a high traction coefficient and an excellent low-temperature fluidity at a higher level and having a high flash point, which contains a ring-containing compound having at least (i) a crosslinked bicyclic ring where two rings are bonded while sharing 3 or more carbon atoms, and (ii) an acyloxy group or a hydrocarbyloxycarbonyl group each containing a branched hydrocarbon group with a main chain having 4 or more carbon atoms, a lubricating oil composition containing the lubricant base oil, and a continuously variable transmission using the lubricating oil composition.

The engine lubricating system can become contaminated with carbon deposits and sludge. Sludge is where the combustion by-products that have entered the oil base saturate this oil base, thus forming a thick carbon rich substance. Sludge is not wanted within the engine. Sludge and or carbon deposits in the motor oil cause problems. Such carbon deposits form in the motor oil from heat, pressure, and namely combustion gases that have leaked pasted the piston rings. Turpentine and terpenes, hereafter referred to as “terpenes”, have shown that these chemicals can breakdown carbon which has been deposited within the engine's oil base.

The lubricating oil composition includes a base oil and a fullerene adduct.

To provide a lubricating oil composition achieving both of high traction coefficient and excellent low temperature fluidity at a higher level and having a high flash point, which contains a naphthene-based synthetic oil (a) having a flash point of 140° C. or higher, and an ester (b) having 5 to 32 carbon atoms and having a branched chain, wherein the content of the naphthene-based synthetic oil (a) based on the total amount of the composition is 35% by mass or more and less than 80% by mass, a method for producing the lubricating oil composition, and a continuously variable transmission using the lubricating oil composition.
