    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: Organic nitrites can be produced from a compound which is a mono/polyhydric alcohol or an aldehyde- or ketone-derivate thereof after de-aeration of the same, using NO gas, and stored in an environment saturated with gaseous NO. Organic nitrites produced according to the invention exhibit less impurities and improved storage stability compared to conventionally produced nitrites. The organic nitrites of the invention can easily be formulated into pharmaceutical compositions and have utility for the treatment of various conditions.

    Abstract: An alkyl nitrite can be produced on an industrial scale with a high efficiency and with a low yield of by-products by the process wherein nitrogen oxide-containing feed gas is brought into an alkyl alcohol liquid in a distillation column reactor while circulating a liquid fraction, produced in the reactor and containing the alkyl alcohol, through a circulation path including a lower section of the reactor and a cooler to remove the reaction heat vigorously generated in the reactor, and while controlling the weight ratio of the circulating liquid fraction to the total alkyl alcohol fed into the reactor to 50:1 to 200:1, the molar ratio of the total alkyl alcohol fed to the reactor and contained in the circulating liquid fraction to nitrogen oxide in the feed gas to 20:1 to 150:1, and the content of the alkyl alcohol in the liquid fraction to 15 to 60% by weight; and the resultant gas fraction containing the target alkyl nitrite is collected from the reactor.

    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.
