2° Amines to N-Nitrosamines: Reaction with NaNO2

2° Amines to N-Nitrosamines: Reaction with NaNO₂

Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

科学领域:

材料科学材料科学材料科学
化学工程是化学工程的重要组成部分.
能量材料能量材料

背景情况:

甘 (NG) 是一种液体爆炸物,需要稳定才能安全处理和储存.
胺 (Mel) 提供了一个潜在的晶体矩阵,用于固定能量材料.

研究的目的:

准备和表征胺和酸甘油 (Mel/NG) 的固体粉状化合物.
研究制备方法对Mel/NG化合物的形态和稳定性的影响.

主要方法:

通过蒸发胺和酸甘油溶液来制备Mel/NG化合物.
使用环境条件蒸发和在降低压力下喷雾闪光蒸发 (SFE).
分析材料形态和稳定性随着时间的推移.

主要成果:

梅尔/NG固体粉状化合物已成功制备,含有高达45%重量的NG.
在SFE过程中,在晶体胺基质中产生了较小的无形酸甘含量.
随着时间的推移,在Mel/NG材料中通过蒸发观察到酸甘的逐渐丧失,这表明长期稳定性有限.

结论:

胺可以作为酸甘的宿主矩阵,形成固体粉状化合物.
SFE方法在控制酸甘含量的形态方面具有优势.
梅尔/NG化合物的长期稳定性受到酸甘蒸发的限制,因此需要进一步研究以提高稳定性.
