A hydraulic fluid comprising a biobased base oil having hydrolytic stability.

A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot.sup.2/side to about 200 mg/foot.sup.2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.

A saturated aliphatic hydrocarbon compound composition having an evaporation loss of 4% by mass or less as determined by the Noack method, a kinetic viscosity at 100 C. of 6.5 mm2/s or less, and an average carbon number of 36 to 44. A lubricating oil composition may contain such a saturated aliphatic hydrocarbon compound composition. A method for producing a saturated aliphatic hydrocarbon compound composition, may include: (1) oligomerizing an olefin to obtain an olefin oligomer; (2) isomerizing the olefin oligomer to obtain an isomer; and (3) hydrogenating the isomer.

The present invention describes a method to produce high purity hydrocarbon materials and the high purity hydrocarbon materials produced from renewable sources. The produced materials are chemically similar and of equal or higher purity to from highly refined mineral oils and/or synthetic hydrocarbons. These renewable hydrocarbon materials can be used as a replacement for mineral and synthetic hydrocarbon base oils, process fluids, white oils in products such as lubricants, rubber, personal care, pharma.

The present disclosure provides a method of producing a lubricant composition comprising the steps of hydrolyzing a starting material to provide a hydrolyzed product mixture, reacting the hydrolyzed product mixture under conditions capable of producing a condensation product mixture, contacting the condensation product mixture with a cyclic compound to provide a coupled product mixture, and hydrogenating the coupled product mixture to provide the lubricant composition. In addition, other methods and compositions thereof are also provided.

A method of dispersing C60 in a lubricant to form a C60 lubricant includes combining C60 with a limonene composition to form a C60 mixture, and heating the C60 mixture to a predetermined temperature for a predetermined time period to dissolve the C60 into the limonene composition to form a C60 concentrate. The method further includes combining the C60 concentrate with a cosolvent to form a blended C60 mixture, and combining the blended C60 mixture with the lubricant to disperse the C60 in the lubricant and to form the C60 lubricant.
