Abstract: Certain branched hydroxyalkyl polyoxylene glycol ethers exhibit excellent characteristics as defoamers or foam-suppressing additives or as foam regulators for aqueous media that contain foaming agents, even at temperatures of 25° C. and below. Therefore, said branched hydroxyalkyl polyoxylene glycol ethers can be used in detergents and cleaning agents.
Abstract: Provided are lubricants containing a synthetic ester, one or more additional base stocks and an additive package along with methods of making and using the same. Lubricant compositions comprise a synthetic ester that is a reaction product of at least one hindered organic polyol with one or more carboxylic acid where at least some (20%) up to 100% of the acids are branched. The lubricant compositions can provide improved oxidation stability and extended service life, as compared to a lubricant whose ester component is the reaction product of one or more hindered organic polyols and one or more carboxylic acids that are all linear, in applications that involve exposure to air, moisture, and/or high temperatures. These lubricant compositions are suited to a variety of lubricant applications, including, but not limited to air compressors, gear boxes, bearing sets, hydraulic systems, and chain drives.
Abstract: Provided are processes for the production of (meth)acrylic esters of polyols, in which for 80 mol % or more of the esters, all of the OH groups of the polyols are esterified. Certain processes relate to reaction of polyols with acrylic acid and/or methacrylic acid in the presence of acidic esterification catalysts and in the presence of polymerization inhibitors, operating with reaction mixtures which are liquid at reaction temperature and are free from nonreacting solvents and/or azeotropic entrainers, the resultant water of condensation being stripped from the gas phase of the reaction space, and the (meth)acrylic acid is metered in three or more portions.
Abstract: Provided are methods for maintaining the ratio of the oxime to equilibrium modifier concentration in solvent extraction circuits, said solvents essentially consisting of at least one ketoxime and/or aldoxime; at least one equilibrium modifier; and at least one diluent.

Abstract: The invention relates to a process for the production of diols with a special structure which are characterized by formula (I). These diols are substances which, besides two OH groups, contain a C?C double bond so that they are suitable as monomers for the production of polymers. The process comprises hydrolyzing a corresponding cyclic precursor in aqueous medium in the presence of an acid dissolved in that medium, the hydrolysis being accompanied by the elimination of a carbonyl compound, and subsequently neutralizing the acid present in the reaction mixture with a base, the base having a pKb value above 0.18 and preferably above 3.0 and being present in heterogeneous form.
