| titleOfInvention | Process for the production of freon |
| abstract | The present invention relates to an integrated process for the production of hydrogen fluoride, trichlorofluoromethane and dichlorodifluoromethane via the intermediate reaction between sodium bifluoride and hydrogen chloride. Sodium bifluoride is prepared from the reaction of ammonium fluoride and hydrogen fluoride with sodium nitrate. Ammonium fluoride may be prepared, in turn, by the reaction of fluosilicic acid with ammonia and water. The principal intermediate reaction between sodium bifluoride and hydrogen chloride results in the manufacture of hydrogen fluoride which may be utilized either to prepare freons by reaction with carbon tetrachloride or to prepare freons together with hydrogen fluoride by reaction with a mixture of methane and chlorine. |
