Abstract: The present invention is a method of producing dry, alkali metal or ammonium carboxylic acid salt particles. In accordance with the invention, a molten carboxylic acid is mixed with a solution of an alkali metal-containing or ammonium-containing alkaline compound and the carboxylic acid and alkaline compound are reacted to form the carboxylic acid salt. Water is then removed from the carboxylic acid salt to produce dry, carboxylic acid salt particles. The feed ratio of the molten carboxylic acid and the alkaline compound is controlled to neutralize the carboxylic acid in the process.

Abstract: Monoester monoacid fluoride of dicarboxylic acid is produced by allowing dicaroxylic acid fluoride represented by the following general formula: FOCCF(CF3)OCF2(A)p(CF2)qCOF where A is a bifunctional perfluorinated group having 1 to 10 carbon atoms; p is 0 or 1; and q is 0 or an integer of 1-10, to react with an alcohol having at least 3 carbon atoms, thereby esterifying the terminal CF2COF group. Such selective monoesterification reaction is effective for separation and purification of a dicarboxylic acid difluoride isomer mixture comprising symmetrical dicarboxylic acid difluoride and asymmetrical dicarboxylic acid difluoride.

The composition is prepared by reacting in an aqueous solution a calcium oxide and/or hydroxide, an amino acid, and a soluble metal sulfate salt at a ratio sufficient to allow substantially all of the ions present in solution to react forming a metal amino acid chelate and an essentially inert calcium sulfate, and wherein the metal amino acid chelate has a ligand to metal molar ratio from 2:1 to 3:1.

Abstract: A process for separating a compound from a mixture of different compounds is disclosed for compounds comprising at least two negatively charged groups connected by a linker group. The process comprises treating the mixture with a material comprising layers containing at least two different types of cation disposed in an ordered arrangement within each layer, such as layers of formula LiAl2(OH)6+, in order to separate the compound from the mixture by selective intercalation of the compound into the material.

Abstract: This invention describes a method of MCC production by means of the following process: first, treating a cellulose source material with an alkaline solution which induces swelling of the cellulose source material; second, addition of hydrogen peroxide and/or other peroxides to reduce viscosity; and third, separation of MCC from the suspension. The alkaline MCC obtained must thereafter be treated with an acid solution to become pH neutral. The MCC is separated and is then ready for drying, and subsequent use in commercial applications.
