Systems and methods of producing chemical compounds are disclosed. An example chemical production system includes a combustion chamber having intake ports for entry of a gas mixture. An igniter ignites the gas mixture in the intake chamber to facilitate a reaction at a high temperature and high pressure. A nozzle restricts exit of the ignited gas mixture from the combustion chamber. An expansion chamber cools the ignited gas. The expansion chamber has an exhaust where the cooled gas exits the expansion chamber. A chemical compound product is formed in the expansion chamber. |

A complex method was developed for the conversion of an ammonium fluoride solution and an ammonium fluoride/potassium fluoride solution into sodium bifluoride, active sodium fluoride and hydrogen fluoride, with potassium nitrate as a co-product and a concentrated solution of ammonium nitrate as a by-product. Quickly settling crystals of sodium bifluoride containing a very small amount of water after centrifugation are obtained with high efficiency from the reaction which occurs during the mixing of a concentrated solution of sodium fluoride in aqueous nitric acid with the ammonium fluoride solution. The by-product of the reaction is a very concentrated solution of ammonium nitrate. Potassium nitrate is precipitated from the ammonium fluoride/potassium fluoride solution after the addition of ammonium nitrate and after cooling. The mother solution formed in the crystalization is applied to the precipitation of sodium bifluoride. The production of hydrogen fluoride and active sodium fluoride takes advantage of the technically known thermal decomposition of sodium bifluoride as obtained according to the invention. Active sodium fluoride and hydrogen fluoride can be produced in different ratios, since either product of the thermal decomposition of sodium bifluoride may be partially applied to the precipitation of additional sodium bifluoride. |
