General description
吗啉是一种杂环仲胺。它由二乙醇胺和硫酸的缩合形成。 其在-180℃下的IR光谱和拉曼光谱已有报道。 吗啉的晶体结构已150K条件下确定。 8至40GHz区域内吗啉的微波光谱已有研究。 据报道，抗坏血酸阴离子和谷胱甘肽可抑制二氧化氮和吗啉之间的水反应。 拉曼光谱和理论计算的构象研究表明，吗啉的赤道椅构象在纯液态中占主导地位。 利用 分支杆菌菌株RP1降解吗啉已有报道。
Application
吗啉适合用作通过分支杆菌菌株对吗啉进行生物降解研究中的试验化合物。
它可用于以下研究：
它可用于以下研究：
- 与O- 甲酰基苯硼酸一起，作为1,3-二氢-1-羟基-3-吗啉-4-基-2,1-苯并氧杂硼杂环戊烯的合成反应物。
- 作为缓蚀剂并保持锅炉给水的碱性pH值。
- 作为吗啉的双（β-酮烯醇化物）镍（II）加合物中的反应物。
- 作为用于比色定量测定C-2未取代的吩噻嗪衍生物的试剂之一。
- 作为α,β-不饱和化合物的定量测定中的反应物。
