Copper-Substituted Chromium Oxide Compositions, Their Preparation, and Their Use as Catalysts and Catalyst Precursors

A crystalline alpha-chromium oxide where from about 0.05 atom % to about 5 atom % of the chromium atoms in the alpha-chromium oxide lattice are replaced by divalent copper (Cu+2) atoms is disclosed. Also disclosed is a chromium-containing catalyst composition comprising as a chromium-containing component the crystalline copper-substituted alpha-chromium oxide; and methods for preparing a composition comprising the crystalline copper-substituted alpha-chromium oxide. One method involves (a) co-precipitating a solid by adding ammonium hydroxide to an aqueous solution of a soluble copper salt and a soluble trivalent chromium salt that contains at least three moles of nitrate per mole of chromium in the solution and has a copper concentration of from about 0.05 atom % to about 5 atom % of the total concentration of copper and chromium in the solution; and after at least three moles of ammonium per mole of chromium in the solution has been added to the solution, (b) collecting the co-precipitated solid formed in (a); (c) drying the collected solid; and (d) calcining the dried solid. Another method involves (a) preparing an aqueous solution of a soluble copper salt and a soluble trivalent chromium salt that contains a copper concentration of from about 0.05 atom % to about 5 atom % of the total concentration of copper and chromium in the solution, (b) evaporating the solution to dryness, and (c) calcining the dried solid. Also disclosed is a chromium-containing catalyst composition comprising a chromium-containing component prepared by treating the crystalline copper-substituted alpha-chromium oxide with a fluorinating agent; and a process for changing the fluorine distribution (i.e., content and/or arrangement) in a hydrocarbon or halogenated hydrocarbon in the presence of a catalyst. The process involves using as the catalyst a composition comprising the crystalline copper-substituted alpha-chromium oxide and/or the treated copper-substituted alpha-chromium oxide.

Compositions containing chromium, oxygen and gold, their preparation, and their use as catalysts and catalyst precursors

A catalyst composition is disclosed that includes chromium, oxygen, and gold as essential constituent elements. The amount of gold in the composition is from about 0.05 atom % to about 10 atom % based on the total amount of chromium and gold. Also disclosed is a process for changing the fluorine distribution (i.e., content and/or arrangement) in a hydrocarbon or halogenated hydrocarbon in the presence of the catalyst composition; and methods for preparing said catalyst composition. One preparation method involves; (a) co-precipitating a solid by adding ammonium hydroxide (aqueous ammonia) to an aqueous solution of a soluble gold salt and a soluble chromium salt that contains at least three moles of nitrate per mole of chromium in the solution and has a gold content of from about 0.05 atom % to about 10 atom % of the total content of gold and chromium in the solution to form an aqueous mixture containing co-precipitated solid; (b) drying the co-precipitated solid formed in (a); and (c) calcining the dried solid formed in (b) in an atmosphere containing at least 10% oxygen by volume. Another preparation method involves (a) impregnating solid chromium oxide with a solution of a soluble gold salt, (b) drying the impregnated chromium oxide prepared in (a); and optionally, (c) calcining the dried solid. A third preparation method involves (a) evaporating an aqueous solution of chromium(VI) oxide and a soluble gold salt to form a solid; (b) drying the solid formed in (a); and (c) calcining the dried solid formed in (b) in an atmosphere containing at least 10% oxygen by volume.

PROCESSES FOR THE PRODUCTION OF FLUOROPROPANES AND HALOPROPENES

A process is disclosed for making CF3CF2CH3, CF3CF=CH2 and/or CF3CCI=CH2. The process involves reacting at least one starting material selected from the group consisting of halopropanes of the formula CX3CH2CH2X, halopropenes of the formula CX3CH=CH2 and halopropenes of the formula CX2=CHCH2X, wherein each X is independently F or Cl, with HF and CI2 in a reaction zone to produce a product mixture comprising HF, HCI, CF3CF2CH3, CF3CF=CH2, and CFsCCI=CH2; and recovering the CF3CF2CH3, CF3CF=CH2 and/or CFsCCI=CH2 from the product mixture. Also disclosed is a process for making CF3CH2CHF2, CFsCH=CHF, and/or CFaCH=CHCI. This process involves reacting at least one starting material selected from the group consisting of halopropenes of the formula CX3CH=CH2 and halopropenes of the formula CX2=CHCH2X, wherein each X is independently F or Cl, with HF and CI2 in a reaction zone to produce a product mixture comprising HF, HCI, CF3CH2CHF2, CFsCH=CHF and CF3CH=CHCI; and recovering the CF3CH2CHF2, CFsCH=CHF, and/or CF3CH=CHCI from the product mixture. The molar ratio of HF to the total amount of starting materials fed to the reaction zone for both of these processes is at least stoichiometric, and the molar ratio of Cl2 to total amount of starting material fed to the reaction zone for both of these processes is 2:1 or less.
