  • HIGH VISCOSITY BASE FLUIDS BASED ON OIL COMPATIBLE POLYESTERS PREPARED FROM LONG-CHAIN EPOXIDES
    Publication number: 20230257674
    Abstract: A polyester is useful as a high viscosity base fluid. A method for its preparation involves epoxidizing an alpha-olefin, reacting the alpha-epoxide or diol with a saturated linear aliphatic dicarboxylic acid, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.
    Type: Application
    Filed: July 1, 2021
    Publication date: August 17, 2023
    Applicant: Evonik Operations GmbH
    Inventors: Stefan Karl Maier, Peter Altenbuchner, Fabian Ziegler, Christiane Zatocil, Stefan Hilf, Emily Clare Schweißinger, Jens Elsner
  • HIGH VISCOSITY BASE FLUIDS BASED ON OIL COMPATIBLE POLYESTERS
    Publication number: 20230257673
    Abstract: A polyester is useful as a high viscosity base fluid. A method for its preparation involves isomerizing an alpha-olefin, epoxidizing an internal olefin, reacting an internal epoxide, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.

  • Process for Heterogeneous Isomerization of alpha-Olefins
    Publication number: 20220380276
    Abstract: A method for the isomerization of alpha-olefins to the corresponding internal olefins uses a heterogenous catalyst containing silicon-aluminum mixed oxide in a continuous fixed-bed operation mode.
