The present invention is generally directed to methods of making application-specific finished lubricant compositions comprising bio-derived diester species. In some embodiments, bio-derived fatty acid moieties are reacted with Fischer-Tropsch/gas-to-liquids reaction products and/or by-products (e.g., gas-to-liquids-produced α-olefins) to yield bio-derived diester species that can then be selectively blended with base oil and one or more additive species to yield an application-specific finished lubricant product having a biomass-derived component.

Swash plate for swash plate compressor and swash plate compressor

Номер: US20130174724A1

Автор: Naonari Tanigawa, Norikazu Muneda, Yoshio Oki

Принадлежит: NTN Corp

The present invention provides a swash plate, for a swash plate compressor, which is excellent in a resistance to the occurrence of seizing in a condition where an extreme pressure is generated owing to local contact between the swash plate and a shoe which slides thereon and in a condition where lubricating oil is depleted, capable of preventing cavitation-caused erosion of a resin film when the swash plate is operated at a high surface pressure and a high speed in the presence of the lubricating oil and the swash plate compressor having the swash plate. A swash plate ( 3 ) for a swash plate compressor is so constructed that inside a housing ( 1 ) where a refrigerant is present, the refrigerant is compressed and expanded by converting a rotational motion of the swash plate ( 3 ) mounted perpendicularly and obliquely on a rotational shaft ( 2 ) by directly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) or indirectly fixing the swash plate ( 3 ) to the rotational shaft ( 2 ) through a coupling member into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ) into a reciprocating motion of a piston ( 5 ) through a shoe ( 4 ) which slides on the swash plate ( 3 ). A resin film containing 25 to 70 parts by weight of fluororesin and 1 to 20 parts by weight of graphite for 100 parts by weight of matrix resin and having a tensile shear adhesive strength not less than 25 MPa is formed on a sliding contact surface of the swash plate ( 3 ) on which the shoe ( 4 ) slides.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

Lubricating oil composition for refrigerating machines

Номер: US20150065407A1

Автор: Tadashi Kisen, Tomoya Matsumoto

Принадлежит: Idemitsu Kosan Co Ltd

A lubricating oil composition for refrigerating machines contains a base oil and an additive in a form of a hydrocarbon compound having a biphenyl structure or a stilbene structure. When the present lubricating oil composition for refrigerating machines is used in refrigerating equipment such as an open-type automobile air-conditioner, an electric automobile air-conditioner, a gas heat pump, other air-conditioning equipment, a refrigerating machine, a vending machine, a showcase, a water-heating system and a refrigerating/heating system, it is possible to detect the leakage of a refrigerant with a long-lasting stability. Therefore, when an unsaturated chlorofluorocarbon refrigerant with a poor stability is used in the above-listed equipment, the present lubricating oil composition for refrigerating machines is significantly advantageous.

A method of producing high purity polyol esters comprises reacting a polyol with an excess amount of a linear or branched aliphatic monocarboxylic C3-20 acid to esterify less than the total amount of the polyol present to form an intermediate reaction composition having a hydroxyl value of from 7 to about 50 mg KOH/g. An anhydride of the corresponding linear or branched aliphatic monocarboxylic C3-20 acid is added to the intermediate reaction composition in an amount of from 1 to about 2.5 equivalents of available OH in the intermediate composition to form a reaction mixture. The reaction mixture is heated for 5-30 minutes or until all of the corresponding anhydride has reacted to form a reaction product. The reaction product is then de-acidified. No metal or acid catalyst or bleaching agents are present in any of the above reaction steps at a concentration above about 15 ppm.
