    摘要: There is provided methods for making a catalyst composition represented by the formula MX/M′F2 wherein MX is an alkali metal halide; M is an alkali metal ion selected from the group consisting of Li+, Na+, K+, Rb+, and Cs+; X is a halogen ion selected from the group consisting of F−, Cl−, Br−, and I−; M′F2 is a bivalent metal fluoride; and M′ is a bivalent metal ion. One method has the following steps: (a) dissolving an amount of the alkali metal halide in an amount of solvent sufficient to substantially dissolve or solubilize the alkali metal halide to form an alkali metal halide solution; (b) adding an amount of the bi-valent metal fluoride to the alkali metal halide solution to form a slurry of the alkali metal halide and bi-valent metal fluoride; and (c) removing substantially all of the solvent from the slurry to form a solid mass of the alkali metal halide and bi-valent metal fluoride. Another method has the following steps: (a) adding an amount of hydroxide, oxide, or carbonate of an alkali metal to an aqueous solution of a hydrogen halide and reacted to form an aqueous solution of an alkali metal halide; (b) adding an amount of a hydroxide, oxide, or carbonate of a bivalent metal to an aqueous solution of hydrogen fluoride and reacted to form a precipitate of a bivalent metal fluoride; (c) admixing the alkali metal halide solution and the bivalent metal fluoride precipitate are admixed to form an aqueous slurry; and (d) removing water from the aqueous slurry to form a solid mass. There is also a method for making a fluorinated olefin.

    摘要: The present disclosure provides methods for pre-treating activated carbon before it is used in a dehydrochlorination process. The methods can comprise mixing the activated carbon with an acid, an oxidizing agent in a liquid phase, or an oxidizing agent in a gas phase. Activated carbons undergoing one or more of these methods can exhibit improved stability during the dehydrochlorination process.
