| titleOfInvention | Process for the production of high purity hydrofluoric acid |
| abstract | The invention relates to a new process for the production of high-purity hydrofluoric acid which meets the high quality requirements, e.g. B. the electronics industry, should suffice. DOLLAR A According to the concept of the invention, the inorganic compound is hydrogen fluoride, which by small amounts of semimetals such. B. B, Si, Ge, As, Sb, Se, Te and Po or metals such as. B. Ca, Mg, Fe, etc. is contaminated with suitable reactants in organic fluorine compounds containing only carbon, fluorine and possibly hydrogen. DOLLAR A The fluorine-containing organic compounds are now subjected to various cleaning stages which are characteristic and very effective for organic substances. The resulting very pure organic fluorine compounds are decomposed by suitable measures in such a way that very pure inorganic hydrofluoric acid as well as carbon dioxide and water are produced. DOLLAR A In particular, simple derivatives from the series of methane or ethane compounds can be used as fluorine compounds, preferably mono-, di-, tri- and tetrafluoromethane or tetra-, penta- or hexafluoroethane, the preparation of which in a manner known per se mostly from analogous chlorine compounds. |
