胺化是指向有机物分子中引入氨基(-NH2)生成胺的反应过程,有时也称氨解。 最常用的胺化剂是氨水、氨气和液氨,有时也用碳酸氢铵、尿素、伯胺和仲胺等。
The different varieties of catalysts,process conditions (temperature,hydrogen partial pressure,etc. ) have an effect on amination process and quality control of products.
通过不同品种催化剂、工艺条件(温度、氢气分压等)对胺化反应进程的质量控制进行了讨论,认为胺化反应最终产物粗叔胺中伯/仲胺及残余醇的含量是影响成品质量的关键因素。
