Title
(EN) ANTIOXIDANT MIXTURE FOR LOW VISCOUS POLYALKYLENE GLYCOL BASESTOCK
(FR) MÉLANGE ANTIOXYDANT POUR HUILE DE BASE DE POLYALKYLÈNE GLYCOL À FAIBLE VISCOSITÉ
Abstract
(EN)
The invention relates to a lubricant comprising a polyalkylene glycol basestock, an aromatic amine of the formula (I) as defined hereinafter, and a thioether of the formula (II) as defined hereinafter. The invention further relates to a method for preparing the lubricant comprising the step of contacting the polyalkylene glycol basestock, the aromatic amine of the formula (I), and the thioether of the formula (II); and to a method for reducing the oxidative degradation of the lubricant comprising the step of contacting the polyalkylene glycol basestock, the aromatic amine of the formula (I), and the thioether of the formula (II).
(FR)
L'invention concerne un lubrifiant comprenant une huile de base de polyalkylène glycol, une amine aromatique de formule (I) telle que définie ci-après, et un thioéther de formule (II) telle que définie ci-après. L'invention concerne en outre un procédé de préparation du lubrifiant comprenant l'étape consistant à mettre en contact l'huile de base de polyalkylène glycol, l'amine aromatique de formule (I) et le thioéther de formule (II); et un procédé de réduction de la dégradation par oxydation du lubrifiant, comprenant l'étape consistant à mettre en contact la base de polyalkylène glycol, l'amine aromatique de formule (I), et le thioéther de formule (II).
