    Abstract: A method for producing nitrous acid ester in which nitric oxide, oxygen, and an alcohol are reacted, thereby generating nitrous acid ester includes a step of generating nitrous acid ester by supplying a bottom liquid from a bottom part of the reaction column, and nitric oxide and/or carbon monoxide, a step of supplying nitrous acid ester to the reaction column; a step of supplying a reaction liquid containing water, nitric acid, and the alcohol to a nitric acid condensing column from the reactor; and a step of separating a low-boiling point component by distillation from the reaction liquid under control of a concentration of the alcohol in a condensed liquid being generated at a bottom part of the nitric acid condensing column to be less than 4.0% by weight so as to introduce the condensed liquid into the reactor from the nitric acid condensing column.

    Abstract: Nitration of organic compounds and organic nitrogen compounds produced.Organic nitrogen compounds are formed in the vapor phase by organic radical formation by reaction of an organic compound with hydroxyl radicals derived from the reaction between hydrogen peroxide and nitrogen dioxide and the nitration of the organic radicals, suitably with nitrogen dioxide. The process may be conducted as a single stage process using an excess of nitrogen dioxide over that required for hydroxyl radical formation. The production of hydroxyl radicals is maximized by the use of a catalytic solid surface such as a solid acid or an acidic oxide or mixed oxide. The product may be a mixture of some or all of the nitrite, nitrate and nitro-derivative which may be used as such, e.g. as a fuel additive, as a source of the individual compounds or as a feedstock for a further synthesis.

    Abstract translation: 生成有机化合物和有机氮化合物的硝化。 通过有机化合物与过氧化氢和二氧化氮之间的反应衍生的羟基自由基反应形成有机氮化合物，并适当地用二氧化氮硝化有机氮化合物。 该方法可以作为使用过量二氧化氮超过羟基自由基形成所需的二氧化氮的单阶段方法进行。 通过使用催化固体表面如固体酸或酸性氧化物或混合氧化物，使羟基自由基的产生最大化。 产物可以是一些或全部亚硝酸根，硝酸根和硝基衍生物的混合物，可以如此使用。 作为燃料添加剂，作为单独化合物的来源或作为进一步合成的原料。
