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. The generated and collected gas mixture is then mixed with oxygen, thus the nitric oxide in the gas mixture converts—by reacting with oxygen—into nitrogen dioxide, then this homogeneous gas is dissolved in water, thus giving us nitric acid. In this chemical reaction system two sets of chemical reactions take place; one on the surface of the solution(s) that produces the main part of the gas mixture, and this is the major part of the chemical reaction system. In the liquid phase of the reaction processes form the metallic ascorbates as well as the alkyl ascorbates. All the same can be done with isoascorbic acid; the chemical reactions will go somewhat slower.
在这项发明中,建立了新的化学反应和新的化学过程,这些化学反应和化学过程可以与设计的系统一起使用,以产生二氧化氮、一氧化氮、硝酸以及金属抗坏血酸盐或烷基抗坏血酸盐,无论是作为主要产品还是作为次要产品。抗坏血酸溶液在室温或升高温度下与硝酸钠、硝酸钾、硝酸钙或烷基硝酸盐(如异丁基硝酸盐、钡硝酸盐或银硝酸盐溶液)反应。所有第二反应物,除了烷基硝酸盐(如异戊基硝酸盐、异丙基硝酸盐或异丁基硝酸盐),以及第一反应物抗坏血酸,均为水溶液。反应容器中含有抗坏血酸溶液;在一定压力下,所选的水溶性硝酸盐溶液被输送到这个溶液中。通过添加所选的硝酸盐溶液,产生氮氧化物和一氧化氮的气体混合物。生成并收集的气体混合物然后与氧气混合,因此气体混合物中的一氧化氮通过与氧气反应转化为二氧化氮,然后这种均相气体被溶解在水中,从而产生硝酸。在这种化学反应系统中,发生了两组化学反应;一组在溶液表面上产生气体混合物的主要部分,这是化学反应系统的主要部分。在反应过程的液相中形成金属抗坏血酸盐和烷基抗坏血酸盐。使用异抗坏血酸也可以完成相同的操作;化学反应速度会稍慢一些。
