Abstract: In the invented process for producing a nitro compound, an organic substrate and nitrogen dioxide are reacted in the presence of oxygen or are reacted in a molar ratio of nitrogen dioxide to the organic substrate of less than 1 to yield a corresponding nitro compound. The reaction may be performed in the presence of N-hydroxyphthalimide or other imide compounds. Such organic substrates include (a) aliphatic hydrocarbons, (b) alicyclic hydrocarbons, (c) non-aromatic heterocyclic compounds each having a carbon atom on a ring, which carbon atom is bonded to a hydrogen atom, (d) compounds each having a carbon-hydrogen bond at the adjacent position to an aromatic ring, and (e) compounds each having a carbon-hydrogen bond at the adjacent position to a carbonyl group. This process can efficiently nitrate an organic substrate even under relatively mild conditions.

Abstract: 本发明提供一种硝酸烷基酯的生产方法,以离心萃取设备为酯化反应分离器,使含有硫酸和硝酸的混合酸溶液从离心萃取设备的重相入口进入,使烷基醇从离心萃取设备的轻相入口进入,烷基醇与硝酸的进料摩尔比为1:1.0-3.0,混合酸与烷基醇在10~60 ℃的温度和800-2000转/分的转速下进行酯化反应;生成的粗酯和废酸在离心力的作用下分为轻相和重相,轻相粗酯经离心萃取器的轻相出口被排出,重相废酸经离心萃取器的重相出口被排出;粗酯经常规碱洗和水洗后,脱水干燥、净化,得到精制的硝酸烷基酯。本发明的方法使酯化反应、反应产物与废酸的分离在同一反应器内同时完成,极大地缩短了反应产物与废酸的接触时间,有效地避免了副反应的发生,从根本上保证了酯化过程的安全。

Abstract: 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.
