Page/Page column 8-9, (2011/10/13)
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.

Page 6 - 7, (2008/06/13)
A process for the preparation of compounds of formula: HO-A-ONO2 (I) wherein A is a C2-C6 alkylene chain by nitration of the corresponding alkanediols with "stabilised" nitric acid is herein disclosed. The process is safer to operators and allows to obtain advantageous yields on an industrial scale.
