Abstract:
The invention relates to a lubricant containing one or more compounds selected from among the keto compounds of general formula (I) and/or metal compounds produced from said compounds, wherein R1, R2, and X have the indicated meaning.
Abstract:
The invention relates to a process for producing ketones or hydrocarbon base oil from fatty acids preferably derived from a biological origin or other renewable source. The process is directed at making an aliphatic ketone or a mixture of aliphatic ketones having 14 to 52 carbon atoms, comprising a ketonization reaction of a fatty acid in a vapor phase with a decarboxylation-coupling catalyst to provide ketones, which can be deoxygenated to give saturated hydrocarbons, unsaturated hydrocarbons, and mixtures thereof. Base oils and transportation fuels may be produced from the process herein.
Abstract:
A release agent, the preparation and use thereof are provided. The release agent, which comprises the following constituents: a hydrosilicone, a catalyst for dehydrogenation condensation, and a solvent, is a semi-permanent release agent. The release agent has the advantages of simple composition, rapid curing under low temperature, low transferring of release agent, less amount of wax accumulation, convenient application and low cost, the release agent is especially suitable for the manufacturing of polyurethane foam articles, epoxy resin articles, rubber articles and polyester articles to promote the mold-releasing of polymer materials.
Abstract:
The present invention provides compositions that are useful for compatibilizing a conventional, non-polar, compression refrigeration lubricant and a hydrofluorocarbon and/or hydrochlorofluorocarbon refrigerant in a compression refrigeration apparatus. Additionally, these compositions promote efficient return of lubricant from the non-compressor zones to the compressor zones of the aforesaid refrigeration apparatus.

Abstract:
This application relates to derivatives of hydrocarbon terpenes (e.g., myrcene or farnesene), to methods of making the derivatives, and to the use of the derivatives as oils, solvents, lubricants, additives or base oils for lubricant compositions, surfactants, plasticizers, and/or as monomers, cross-linking agents, curing agents or reactive diluents for use in making oligomers or polymers.
Abstract:
Disclosed is a multiphase lubricant composition formed of an emulsion containing (a) a lubricant first phase, (b) a second phase formed of boric acid and a liquid that is a solvent for boric acid, but immiscible in the first phase, such as glycerol, and (c) a surfactant.
Abstract:
A non-deleterious coating composition for the deposition of a dry film lubricant coating on a rubber sealing element comprises: (a) 1 to 10% by weight of a component selected from the group consisting of waxes and normally solid aliphatic alcohols; (b) 1 to 10% by weight of a lubricating oil; and (c) the balance being a solvent for (a) and (b); wherein the solvent, when applied to the rubber sealing element, in said coating composition, evaporates from the coating composition before any substantial degradation of the physical properties of the rubber sealing element occurs. A method for coating a rubber sealing element and the rubber sealing element coated with the dry film lubricant are also disclosed. The invention finds particular applicability in the lubrication of rubber sealing elements, e.g., O-rings, which will be utilized in the manufacture of devices by automated assembly techniques.
