    Abstract: Methods of forming a nitrate ester include combining at least one nitrate salt and sulfuric acid to form a nitrating solution and adding an aliphatic polyol to the nitrating solution. Nitrate esters formed by this method may be, for example, triethylene glycol dinitrate (TEGDN), pentaerythritol tetranitrate (PETN), diglycerol tetranitrate (DGTN), 1,1,1-tris(methylol)ethane trinitrate (TMETN), 1,2,4-butanetriol trinitrate (BTTN), nitroglycerin (NG), diethylene glycol dinitrate (DEGDN), ethylene glycol dinitrate (EGDN), metriol trinitrate (MTN), nitrocellulose (NC), or 1,2-propanediol dinitrate (PDDN).

    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.
