Abstract
A method for completely reducing an inorganic halide to obtain a non-halogen inorganic substance and/or hydride thereof and preferably anhydrous hydrogen halide fluid using inorganic halide substances, such as sulfur hexafluoride, nitrogen trifluoride, tungsten hexafluoride, uranium hexafluoride and others by reduction with a reducing agent at a proper temperature. The reducing agents may be molecular hydrogen, inorganic hydrides and inorganic metallic elements; molecular hydrogen is preferable, but in certain instances the inorganic hydrides are used, as well as inorganic metallic elements such as calcium and magnesium.
Claims16
A method for the synthesis of anhydrous hydrogen halide and at least one non-halogen inorganic substance comprising:
- fully and anhydrously reacting one or more inorganic halides with only one reducing agent to produce anhydrous hydrogen halide and at least one non-halogen inorganic substance, wherein the reducing agent is hydrogen and wherein the reaction is carried out at a reaction zone temperature such that Tm≦TRZ<Tb, wherein Tm is the melting point of the non-halogen inorganic substance, TRZ is the temperature of the reaction zone, and Tb is the boiling point of the non-halogen inorganic substance.
A method for the synthesis of anhydrous hydrogen fluoride and at least one non-halogen inorganic substance comprising:
- anhydrously reacting one or more inorganic fluorides with only one reducing agent to produce anhydrous hydrogen fluoride and at least one non-halogen inorganic substance, wherein the reducing agent is hydrogen and wherein the reaction is carried out at a reaction zone temperature such that Tm≦TRZ≦Tb, wherein Tm is the melting point of the non-halogen inorganic substance, TRZ is the temperature of the reaction zone, and Tb is the boiling point of the non-halogen inorganic substance.
