Synthesis of nitrogen-containing organic compounds (NOCs), especially higher-order NOCs, is very energy intensive, and traditional methods emit a high amount of CO₂ equivalents into the environment. To lower emissions and alleviate the energy requirements of the process, we propose the use of gas over liquid non-thermal plasma (NTP) as a substitute. In this work, we investigate the formation of higher-order NOCs from butylamine and subsequently study the process’s changing reaction chemistry with gas mixtures, reactor temperature, and treatment time. Different compounds in the form of aliphatic and aromatic amines, nitriles, and azoles were observed. Under the optimized conditions, our proposed reactor was able to achieve a production efficiency of 49.4 g/kWh with pure argon gas at −20 °C. The selectivity of the products varied with gas mixtures, reactor temperature, and treatment time due to altering reaction pathways which are discussed in more detail. An insight into the dielectric barrier discharge (DBD) conditions for obtaining different plasma chemistry in NOC synthesis can thus provide a foundation to develop a novel synthetic approach.

利用微秒脉冲介质阻挡放电从丁胺合成高阶含氮有机化合物

含氮有机化合物(NOCs)尤其是高阶NOCs的合成是非常耗能的，传统方法会排放大量CO ₂等价物进入环境。为了降低排放并减轻工艺的能源需求，我们建议使用气体非热等离子体 (NTP) 作为替代品。在这项工作中，我们研究了丁胺形成高阶 NOC 的过程，并随后研究了该过程随气体混合物、反应器温度和处理时间的变化而变化的反应化学。观察到脂肪族和芳香族胺、腈和唑形式的不同化合物。在优化条件下，我们提出的反应器能够在-20℃下使用纯氩气实现49.4g/kWh的生产效率。由于反应途径的改变，产物的选择性随气体混合物、反应器温度和处理时间而变化，对此将进行更详细的讨论。
