hydrogenolysis is introduced to achieve a fast, inexpensive and widely applicable procedure. In addition to the synthetic part, Fourier transform infrared (FTIR) spectroscopy using a fibre optic attenuated total reflection (ATR) sensor was applied to monitor the formation of sensitive key intermediates, resulting in optimized reaction times. By applying this in-line technique, the possibility of real-time
描述了一种方便的合成高达12个单元的单分散低聚(乙二醇)的方法。引入了一种新颖的裂解方案来代替费力的氢解反应,以实现快速,廉价且可广泛应用的程序。除合成部分外,还应用了使用光纤衰减全反射(ATR)传感器的傅立叶变换红外(FTIR)光谱技术来监测敏感关键中间体的形成,从而优化了反应时间。通过应用这种在线技术,在惰性条件下进行实时分析的可能性得到了令人印象深刻的证明。
