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).

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).

Abstract: The present invention relates to a method of producing mineral oil from an underground mineral oil deposit, in which an aqueous saline surfactant formulation comprising a surfactant mixture, for the purpose of lowering the interfacial tension between oil and water to <0.1 mN/m, is injected through at least one injection well into the mineral oil deposit and crude oil is withdrawn from the deposit through at least one production well, wherein the mineral oil deposit is at a temperature of ?25° C. and <130° C.

Abstract: Provided is a low volatile organic content (VOC), isocyanate based curable oil-in-water emulsion of a polyisocyanate crosslinker and a surface active isocyanate reactive material in an aqueous medium, and a process for the preparation thereof. Also provided is a water-in-oil intermediate product to which an aqueous medium can be added to produce the curable oil-in-water emulsions. Such curable emulsions are particularly suited for use in coatings applications.
