Disclosed herein are solid-liquid bi-phase lubricating devices that can include a cuboidal shaped stick with at-least one cylindrical or cuboidal shaped hollow core running through entire or partial length of the stick. The cuboidal shaped stick can include a solid polymer-based composite while the inner space is filled with a semi-fluid grease lubricant. The solid polymer-based composite can include one or more polymers, filler materials, corrosion inhibitors, plasticizers, and additives. The grease lubricant can include lithium, lithium-complex, aluminum-complex, calcium-sulphonate complex, bentone-thickened grease, and mixtures thereof and have an NLGI consistency grade1. The lubricating devices can be used for friction reduction of mechanical components involving two or more contacting surfaces in relative motion, such as a steel wheel flange-rail contact interface of transit and freight rail transport systems.

A lubricating oil composition for refrigerating machines contains a base oil and an additive in a form of a naphthalimide compound. A refrigerant used in a refrigerating machine in which the composition is used is unsaturated hydrofluorocarbon (unsaturated HFC) having a GWP of 1000 or less. 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 fron 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 for producing a lubricant base oil that has a predetermined boiling point range, the method including a first step of bringing a feedstock containing a first hydrocarbon oil having a boiling point in the above boiling point range and a second hydrocarbon oil having a lower boiling point than the boiling point range into contact with a hydroisomerization catalyst, wherein the catalyst contains a support that includes a zeolite having a one-dimensional porous structure including a 10-membered ring and a binder, and platinum and/or palladium supported on the support.

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

Disclosed are the use of fluorine substituted olefins, including tetra- and penta-fluoropropenes, in a variety of applications, including in methods of depositing catalyst on a solid support, methods of sterilizing articles, cleaning methods and compositions, methods of applying medicaments, fire extinguishing/suppression compositions and methods, flavor formulations, fragrance formulations and inflating agents.

Compositions which are based on tetrafluoropropene and more particularly relates to compositions inclduing 60% to 90% by weight of 2,3,3,3-tetrafluoropropene and 10% to 40% by weight of at least one compound selected from difluoroethane and difluoromethane, which can be used as a heat transfer fluid. The compositions may include 60% to 79% by weight of 2,3,3,3-tetrafluoropropene and 21% to 40% by weight of a compound selected from difluoroethane and difluoromethane.

A lubricating oil composition for refrigerating machines contains a base oil and an additive in a form of a coumarin compound. 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.
