摘要:
Disclosed is a limonene-sulfur polysulfide and methods for preparing the same. The polysulfide prepared according to these methods is flexible, moldable and otherwise capable of being formed in any manner consistent with a thermoplastic polymer. The limonene-sulfur polysulfide has been demonstrated to sequester inorganic palladium and inorganic mercury dissolved in water.

This invention relates to a lubricating composition comprising a blend of a major amount of an oil of lubricating viscosity, gear or transmission oil package and a top treatment which comprises at least one saturated fatty phosphate ester or salt, wherein the lubricating composition is free of saturated fatty phosphites. In another embodiment, the invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity, at least one saturated fatty phosphate ester or salt, at least one polysulfide and at least one phosphorus antiwear or extreme pressure agent, wherein the lubricating composition is free of saturated fatty phosphites. The invention relates to additive combinations which when added to a lubricant can provide and improve frictional and, optionally, thermal stability properties. The additives include a phosphate ester or salt wherein the hydrocarbyl group of the phosphate is a fatty-saturated group. The top treatment may also include a substituted fatty imidazoline or reaction product of a fatty carboxylic acid and polyalkylene polyamine and/or a borated dispersant.

This invention concerns a process for preparing a sulfurized olefin containing reduced amounts of thiones using a low molecular weight hydrocarbon to precipitate the thiones from the sulfurized olefin.
摘要:
A process for producing a sulfurized olefin product substantially free of ash containing waste is disclosed. The process involves dehydrohalogenation of an olefin/sulfur halide complex by contacting the complex with a protic solvent in the absence of any metal ion. The process allows for the solvolytic dehydrohalogenation of the complex. The sulfurized olefin product obtained is isolated and may be subjected to further processing to remove any remaining halides. The resulting sulfurized olefin is a useful additive in lubricating oils.
摘要:
Various novel urazole compositions have been discovered that may be generally represented by formula (I), wherein T and Q may be the same or different and represent hydrogen, hydrocarbyl, sulfur, phosphorus, boron, a metal cation, acyloxy hydrocarbyl, imido hydrocarbyl, hydrocarbyl repeating units, hydrocarbyl urazole (I) containing repeating units, an acyl urazole repeating units, an acyl group, or hydrocarbyl acyl containing group, a repeating unit of an acyl group, a repeating unit of a hydrocarbyl acyl containing group, or together form a pi bond between the two nitrogen atoms and A is hydrogen, hydrocarbyl, a hydrocarbyl urazole I group, a repeating unit of a hydrocarbyl containing acyl group or a repeating unit of a hydrocarbyl containing acyl group which is bonded directly to or through a hydrocarbyl group to another urazole (I) group. These compositions may be formulated with functional fluids for use in motorized vehicles.
