  • ANTIOXIDANT MIXTURE FOR HIGH VISCOUS POLYALKYLENE GLYCOL BASESTOCK
    Publication number: 20220041949
    Abstract: The invention relates to a lubricant comprising a polyalkylene glycol basestock, a phenol selected from an ester of 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid with a C1-18 aliphatic alcohol, and an aromatic amine of the formula (I) as defined hereinafter. The invention further relates to a method for preparing the lubricant comprising the step of contacting the polyalkylene glycol basestock, the phenol, and the aromatic amine of the formula (I); and to a method for reducing the oxidative degradation of the polyalkylene glycol basestock comprising the step of contacting the polyalkylene glycol basestock, the phenol, and the aromatic amine of the formula (I).

  • OLIGO- OR POLYAMINES AS OXIDATION STABILIZERS FOR BIOFUEL OILS
    Publication number: 20100064576
    Abstract: The use of oligo- or polyamines which have a number-average molecular weight of from 46 to 70 000 and are free of phenolic hydroxyl groups for increasing the oxidation stability of biofuel oils based on fatty acid esters, or of mixtures of such biofuel oils with middle distillates of fossil origin and/or of vegetable and/or animal origin, which are essentially hydrocarbon mixtures and are free of fatty acid esters.

  • Dot 4 brake fluids
    Publication number: 20060264337
    Abstract: A brake fluid comprises a) from 10 to 50, preferably from 20 to 40, % by weight of diethylene glycol and/or dipropylene glycol and b) from 50 to 90, preferably from 60 to 80, % by weight of one or more monoalkyl ethers of (poly)ethylene glycol and/or (poly)propylene glycol. The novel fluids are in particular free of borate and, owing to the low hygroscopicity, are suitable for use in regions of high relative humidity.
