This disclosure provides a process for producing vinylidene dimer derivatives by subjecting one or more vinylidene dimers and one or more carbonyl-containing compounds to a carbonyl-ene reaction, optionally in the presence of a catalyst, to produce one or more vinylidene dimer derived alcohols. This disclosure also provides a process for producing vinylidene dimer derivatives by reacting one or more vinylidene dimers with one or more carbonyl-containing compounds, optionally in the presence of a catalyst, to produce one or more vinylidene dimer derived alcohols. This disclosure further provides vinylidene dimer derivatives (e.g., vinylidene dimer derived alcohols and esters) produced by these processes. This disclosure still further provides for hydrogenating/reacting the vinylidene dimer derived alcohols with acids or anhydrides to produce vinylidene dimer derived esters. This disclosure yet further relates to lubricating ester oil base stocks, and lubricating oils containing the lubricating ester oil base stocks.

A lubricant for a copper alloy die-casting die is mainly prepared by an inorganic nano-powder, an organic substrate material, and an organic resin material. In the present disclosure, the use of oil-based lubricants as a basis and the reduction of the content of oil in the lubricant yield improved oil selection and proportion, which cooperates with the corresponding higher proportion of inorganic powder material mixture and a more suitable spraying amount applied on the surface of the die to exert a good lubricating effect on products with complex and irregular shapes in the inner cavity of a die-casting die. At the same time, the production cost of the lubricant is low. Copper alloy die castings produced after a lubrication process have a high yield rate and smooth surfaces without casting defects.

A de-icing lubricant composition is provided, including isopropyl alcohol; and mineral oil. The isopropyl alcohol may be 60-90% of the composition by weight. The mineral oil may be 10-30% of the composition by weight. The composition may include a dye and/or a propellant. The propellant may be CO2. A method of restoring mobility to frozen components is also provided by applying a composition as described above to a frozen component.

Provided herein is a composition for improving performance of waxless skis, in particular skin skis, more particularly of skin strips, on snow, the composition comprising (a) C.sub.1-6-alcohol(s); and (b) lubricant(s) selected from a group consisting of (c) perfluoropolyethers, (d) polydi(C.sub.1-3-alkyl)siloxanes, and mixtures thereof.

The present invention relates to a functional fluid composition comprising a glycol as a base material and a monoamine-based noise reducer. According to the present invention as such, the functional fluid composition comprising a glycol as a base material and a monoamine-based noise reducer represented by chemical formula 1 has an excellent noise reducing effect. In addition, the functional fluid composition of the present invention has an excellent metal corrosion inhibiting effect even, by using a monoamine-based compound as a noise reducer, when a metal corrosion inhibitor composed of a triazole-based compound without including an amine-based compound is used as a metal corrosion inhibitor.

The present disclosure provide for coatings, coated structures, methods of coating, methods of coating a structure, and the like. In an aspect, the coating is a tribocatalytically-active coating, where the tribocatalytically-active coating interacts with the hydrocarbon environment forming a protective carbon-based tribofilm on the surface of the coating, which can be actively formed (reformed) during use of the coated structure within the hydrocarbon environment.

A single chemical composition comprising to clean and/or lubricate fluid encompassing systems and systems' components comprising of fluid conduit(s), and/or fluid reservoir(s), and/or valve(s), and/or device(s).

Fluid encompassing systems that dispense a fluid or fluids for in vitro and/or in vivo procedures and/or for consumption must be cleaned. A fluid encompassing system and this system's encompassing fluid are both susceptible to contamination

This invention's chemical composition performed routinely cleans the contamination of this system, which also helps maintain the chemical and physical properties for this system's encompassing fluid. This chemical composition also lubricates the surfaces of this system's components. Lubricating this system's components such as valves helps enhance the functioning of said system. This chemical composition also improves this system's fluid flow and helps eliminate odor and foul tasting contaminates from this system.

This chemical composition enhances fluid encompassing systems' operation and efficiency, which helps prolong the life span of these systems and said systems' components.

The present invention relates to specific derivatives of dimer fatty acids, compositions comprising them and a method to reduce pour points.

Provided herein are methods for producing ,-unsaturated ketones from the condensation of methyl ketones in the presence of an amine catalyst. Such amine catalysts may be supported, for example, on a silica-alumina support. Such amine catalysts may be used in the presence of an additional acid. The ,-unsaturated ketones may be produced by dimerization and/or timerization of the methyl ketones. Such ,-unsaturated ketones may be suitable for use in producing fuels, gasoline additives, and/or lubricants, or precursors thereof. The methyl ketones may be obtained from renewable sources, such as by the fermentation of biomass.

A method of making a coating solution includes the steps of polymerising an initial monomer feed comprising an N-vinyl pyrrolidone and an acrylate, preferably methacrylate, salt in water to synthesise a copolymer thereof, acidifying the resulting copolymer-water mixture to give free carboxylic acid groups along the copolymer backbone, diluting the aqueous solution down with alcohol, and adding a cross-linking agent which is capable of reacting with the carboxylic acid groups and curing the copolymer at a later stage after the coating solution has been applied to a substrate and the copolymer coated thereon. Also disclosed are a coating solution in storage, a method of coating a substrate which is on, or is part of, a medical device or other article, a substrate, article or medical device having a coating so applied, and a coated medical device packaged in a hydration solution. The aqueous-alcoholic coating solution may be stored for an extended period, suitably for at least one month and desirably for substantially longer, without deteriorating.
