Abstract: A premixture for producing an absorbent for removing acid gases from a fluid stream containing a) at least a tertiary amine and/or a sterically hindered secondary amine; b) a dicarboxylic acid in an amount, calculated as neutralization equivalent based on the protonatable nitrogen atoms in a), of at least 30%, wherein the dicarboxylic acid has a solubility in water at a temperature of 20° C. of not more than 15 g of dicarboxylic acid per 100 g of water; and c) 20 to 80 wt % of water. Also described is a process for producing an absorbent from the premixture. The premixture is a transportable and readily handleable solution of a dicarboxylic acid having poor solubility in water for producing an absorbent for removing acid gases from a fluid stream.

Abstract: A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition.

Abstract: The present invention provides a metal rolling oil composition excellent in both an emulsion stability and a plating-out property, wherein the metal rolling oil composition comprises: at least one base oil selected from the group consisting of a mineral oil, animal and vegetable fat and oil, and synthetic ester; a surfactant; and an elastomer.

Abstract: The present invention relates to a wax-containing liquid hydrocarbon fuel composition comprising (a) at least one wax-containing liquid hydrocarbon; and b) a transesterified acrylate polymer obtained by transesterifying a starting acrylate polymer with at least one higher alcohol, the transesterified acrylate polymer being present in an amount sufficient to modify the cold flow properties of the wax containing liquid hydrocarbon fuel.
