  • Patent number: 11965140
    Abstract: Low molecular weight polyalkyl acrylate polymers can be used as high viscosity base fluids. A corresponding method can be used for their preparation. Lubricant compositions may contain such low molecular weight polyalkyl acrylate polymers and the compositions may be used 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 hydraulic oils.
    Type: Grant
    Filed: December 12, 2019
    Date of Patent: April 23, 2024
    Assignee: Evonik Operations GmbH
    Inventors: Stefan Karl Maier, Michael Neusius, Qi Xiao, Gabriela Fedor, Stefan Hilf, Frank-Olaf Mähling

  • Patent number: 10316268
    Abstract: The present invention is directed to a basic ionic liquid treatment for removing chloropropanol and/or glycidol, or their fatty acid esters, from glyceride oil, as well as a process for refining glyceride oil which includes the basic ionic liquid treatment. The present invention also relates to uses of the basic ionic liquid and glyceride oil compositions obtained from the ionic liquid treatment.

  • Patent number: 10221374
    Abstract: The present invention relates to a process for refining glyceride oil comprising the steps of: (i) contacting glyceride oil with a liquid comprising a basic quaternary ammonium salt to form a treated glyceride oil; wherein the quaternary ammonium salt comprises a basic anion selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate; and a quaternary ammonium cation; (ii) separating the treated glyceride oil from a salt comprising the quaternary ammonium cation; and (iii) subjecting the treated glyceride oil after the separation step to at least one further refining step; and to the use of contacting a glyceride oil with the basic quaternary ammonium salt for preventing or reducing the formation of fatty acid esters of chloropropanols and/or glycidol upon heating of the glyceride oil.

  • Patent number: 10150933
    Abstract: The present invention relates to a process for removing metal from metal-containing glyceride oil comprising the steps of: (i) contacting a glyceride oil, comprising chromium, manganese, iron, cobalt, nickel and/or copper in a total amount of from 10 mg/kg to 10,000 mg/kg, with a liquid comprising a basic quaternary ammonium salt to form a treated glyceride oil; wherein the basic quaternary ammonium salt comprises a basic anion selected from hydroxide, alkoxide, alkylcarbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, asparaginate, taurinate and lysinate; and (ii) separating the treated glyceride oil from a salt comprising the quaternary ammonium cation, providing a treated glyceride oil containing a reduced amount of metals.
