  • Publication number: 20130203636
    Abstract: Water-based drilling mud lubricants using a blend of fatty acid polyamine salts and fatty acid esters give synergistically better lubricity results than either component used separately. For example, the blends with different ratios of fatty acid diethylenetriamine salt and fatty acid methyl ester demonstrate much better lubricity in water-based drilling fluids than those where only fatty acid diethylene-triamine salt or fatty acid methyl ester are separately used. The amines in fatty acid amine salt might also include other polyamines, such as butanediamine pentamethylenediamine, spermidine, spermine, propylene diamine and propylene polyamines. The fatty acid esters might also include fatty acid ethyl ester, fatty acid glycerol ester and fatty acid trimethylolpropane ester. The carbon numbers of the fatty acids used to make the components in the lubricant blend may range from C4 to C28.

  • Patent number: 8481466
    Abstract: A grease composition using lubricating base oil that is biodegradable by microorganisms in nature and has an affinity to the human body is provided. More particularly, a distillation residue secondarily generated in production of biodiesel from vegetable oil (soybean oil and canola oil) is used as the lubricating base oil. The grease composition is produced by adding 1 to 20 wt % of additives to 100 to 95 wt % of distillation residues, which is generated in production of biodiesel, and 1 to 30 wt % of thickeners.

  • Publication number: 20130035268
    Abstract: Provided are lubricants containing a synthetic ester, one or more additional base stocks and an additive package along with methods of making and using the same. Lubricant compositions comprise a synthetic ester that is a reaction product of at least one hindered organic polyol with one or more carboxylic acid where at least some (20%) up to 100% of the acids are branched. The lubricant compositions can provide improved oxidation stability and extended service life, as compared to a lubricant whose ester component is the reaction product of one or more hindered organic polyols and one or more carboxylic acids that are all linear, in applications that involve exposure to air, moisture, and/or high temperatures. These lubricant compositions are suited to a variety of lubricant applications, including, but not limited to air compressors, gear boxes, bearing sets, hydraulic systems, and chain drives.
