Abstract:

Results confirmed the possibility and expediency of converting silicon fluoride gases evolved in the production of superphosphate to hydrogen fluoride with the simultaneous production of quality silica. The new technological scheme of production ensures the possibility of producing a mixture of ammonium bifluoride and ammonium fluoride with a concentration of 9496. During decomposition of ammonium bifluoride and fluoride with sulfuric acid the degree of liberation of fluorine as hydrogen fluoride reaches 97. The method developed for producing hydrogen fluoride makes it possible to organize this production without harmful waste products. Author
