Usage

General Description

1,1,2-Trichloro-1,3,3,3-tetrafluoropropane, also commonly known as CFC-113a, is a chemical compound used primarily as a refrigerant and in the production of foam products. It is a halogenated hydrocarbon with the molecular formula C3H2Cl3F4, and is a colorless, odorless gas at room temperature. CFC-113a was widely used as a replacement for the ozone-depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) in refrigeration and air conditioning systems. However, its production and use has been phased out due to its contribution to ozone depletion and global warming. Despite its phase-out, 1,1,2-Trichloro-1,3,3,3-tetrafluoropropane can persist in the atmosphere for long periods of time, impacting the environment and human health.

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.

Preparation of composition containing chromium, oxygen, and either silver or palladium, and their use as catalysts and catalyst precursors

A method for preparing a catalyst composition suitable for increasing the fluorine content in a hydrocarbon or a halogenated hydrocarbon is disclosed. The method involves (a) co-precipitating a solid by adding ammonium hydroxide to an aqueous solution of a soluble trivalent chromium salt and a soluble salt of a modifier metal selected from silver and palladium, that contains at least three moles of nitrate (i.e., NO3?) per mole of chromium (i.e., Cr+3) in the solution and has a modifier metal concentration of from about 0.05 atom % to about 10 atom % of the total concentration of modifier metal and chromium in the solution to form an aqueous mixture containing co-precipitated solid and dissolved ammonium nitrate; and after at least three moles of ammonium hydroxide per mole of chromium in the solution has been added to the solution, (b) drying said aqueous mixture formed in (a); and (c) calcining the dried solid formed in (b) in an atmosphere containing at least 10% oxygen by volume (e.g., air). Also disclosed is a catalyst composition comprising alpha-chromium oxide and a modifier metal selected from silver and palladium prepared by the above method. Also disclosed is a process for increasing the fluorine content in a hydrocarbon or halogenated hydrocarbon in the presence of a catalyst; and processes using a catalyst composition comprising chromium, oxygen and a modifier metal selected from siver and palladium as essential constituent elements (e.g., a catalyst composition prepared by the above process). An azeotropic composition involving CF3CCl═CF2 and HF is also disclosed.

PROCESS FOR THE PREPARATION OF 1,1,1,3,3-PENTAFLUOROPROPANE AND/OR 1,1,1,3,3,3,-HEXAFLUOROPROPANE

A process for the manufacture of CF3CH2CHF2 and/or CF3CH2CF3 is disclosed. The process involves (a) reacting HF and at least one halopropene of the formula CX3CCI=CCIX (where each X is independently F or Cl) to produce a product including both CF3CCI=CF2 and CF3CHCICF3; (b) reacting CF3CCI=CF2 and/or CF3CHCICF3 produced in (a) with hydrogen to produce a product including CF3CH2CHF2 and/or CF3CH2CF3; and (c) recovering CF3CH2CHF2 and/or CF3CH2CF3 from the product produced in (b). In (a), the CF3CCI=CF2 and CF3CHCICF3 are produced in the presence of a fluorination catalyst comprising at least one chromium-containing component selected from (i) a crystalline alpha- chromium oxide where at least 0.05 atom % of the chromium atoms in the alpha-chromium oxide lattice are replaced by divalent copper, and (ii) a chromium-containing composition of (i) which has been treated with a fluorinating agent.
