Organic nitrates are prepared from mono-, di- or polyhydric alcohols by (i) simultaneously feeding a first continuous-flow microreactor unit with (a) concentrated nitric acid, (b) acetic anhydride, (c) optionally, a catalytic amount of a strong inorganic acid other than nitric acid, and (d) optionally, a solvent, to obtain a solution of acetyl nitrate, and (ii) simultaneously feeding a second continuous-flow microreactor with the solution of acetyl nitrate obtained in step (i) and said mono-, di- or polyhydric alcohol in liquid form or dissolved in a solvent to obtain a solution of said organic nitrate, and (iii) optionally, isolating said organic nitrate from the solution obtained in step (ii). The process of the invention is particularly suited for mono-nitration of dihydric alcohols such as 1,4-butanediol.
Synthesis of cyclic N-nitrourethanes by the simultaneous oxidative desulfurization and nitration of cyclic thiourethanes

six‐membered cyclicthiourethanes with acetyl nitrate results in a vigorous reaction that generates copious amounts of red–brown nitrogen oxide fumes and produces the corresponding cyclic N‐nitrourethanes in high yields (>95%). The overall yield of the cyclic N‐nitrourethanes starting from an aminoalcohol using the “thiourethane” route is superior to the conventional route going through the cyclic urethane
