  • Patent number: 10358409
    Abstract: Compositions including certain olefinic ester compounds are generally disclosed. In some embodiments, such compositions are compositions having low toxicity, such as low aquatic toxicity. Therefore, in some embodiments, such compositions can be suitable used as solvents or as part of a solvent system for applications where low toxicity is desirable. Such uses include, but are not limited to, cleaning applications on or near waterways, use in oil or gas recovery, and the like. In some other embodiments, such compositions are treatment fluids for oil wells, and can therefore be introduced into an oil well to remove buildup and other deposits. In some embodiments, the olefinic ester compounds are derived from a natural oil or a natural oil derivative.

  • Publication number: 20190062286
    Abstract: Novel compounds are described, being alkylated diphenylamine derivatives of triazole, wherein the alkyl group on at least one of the phenyl groups is C8 or higher, in an amount ranging from 0.001 to 5.0% by weight of the lubricating composition. In particular, the derivatives may be 1-[di-(4-octylphenyl)aminomethyl]triazole; 1-[di-(4-nonylphenyl)aminomethyl]triazole; 1-[(4-octylphenyl)(4-butylphenyl)aminomethyl]triazole; and 1-[(4-octylphenyl)(phenyl)aminomethyl]triazole. A lubricating composition comprising the novel derivatives is also disclosed.
