Abstract: In this invention new chemical reactions, new chemical processes are established, and these chemical reactions, chemical processes can be used with the designed system to produce nitrogen dioxide, nitric oxide and calcium ascorbate or calcium isoascorbate. The reaction vessel contains the aqueous ascorbic acid solution or aqueous isoascorbic acid solution. The temperature in the reaction vessel at the start of the reaction is at temp. 55° C. Into this solution is injected calcium nitrite dissolved in water. The gases generated by the chemical reactions are collected in the gas vessel. Here two sets of chemical reactions take place; one on the surface of the solution that produces the bulk of the gas mixture. In the liquid phase, the reactions go slow; and it gives nitric acid, calcium ascorbate and nitric oxide. Instead of calcium ascorbate one can use isoascorbate, in that case the chemical reactions will go somewhat slower.

Abstract: In this invention new chemical reactions, new chemical processes are established, and these chemical reactions and chemical processes can be used with the system designed to produce nitrogen dioxide, nitric oxide, nitric acid as well as metallic ascorbates or alkyl ascorbates, either as main or as secondary products. Ascorbic acid solution is reacted at room temperature or at elevated temperature with either sodium nitrite or potassium nitrite or calcium nitrite or alkyl nitrite such as isobutyl nitrite or barium nitrite or silver nitrite solution. All the second reactants except alkyl nitrites such as isoamyl nitrite or isopropyl nitrite or isobutyl nitrite, as well as the first reactant, ascorbic acid, are in aqueous solutions. The reaction vessel contains the ascorbic acid solution; into this solution, under, certain pressure, is delivered the choosen aqueous nitrite solution. Gas mixture of nitrogen dioxide and nitric oxide is produced by addition of the choosen nitrite solution.

Abstract: In this invention a new chemical process is established and a system designed to produce those compounds according to the process that is part of this invention. In this chemical system, chemical reactions take place at two places when the reactants are in liquid forms; one sort of chemical reactions take place on the surface of the solution pool and another sort of chemical reactions in the solution medium. From the surface reactions the system produces gases; nitrogen dioxide, nitrogen oxide and water; in the deep, in the solution medium, the system produces solid(s), liquid and gases. The solid(s) may be inorganic salt(s) or organometallic salt(s), and sometimes solid element(s), as iodine, for example. For the liquid it will be nitric acid and water, for the gas, it will be nitrogen oxide, for the solid can be different salt(s), depend on the chemical reaction design.
