摘要

设计和开发了一种低成本的3D打印标准化流动光化学装置，用于大多数实验室使用的光化学灯的压力驱动流动系统。在这项研究中，光化学反应器是用聚丙烯3D打印的，这有助于快速优化反应器的几何形状和灯罩系统的实验设置。为了证明这种优化方法的快速性，在3D打印反应器中，将Kessil LED灯用于一系列甲苯的溴化，收率高，停留时间低至27秒。该反应与间歇光化学反应相比较有利，并且能够扩大到75 mmol h−1的产率。

3D printed reactors and Kessil lamp holders for flow photochemistry: design and system standardization

A low-cost 3D printed standardized flow-photochemistry setup has been designed and developed for use with a pressure-driven flow system using photochemistry lamps available in most laboratories. In this research, photochemical reactors were 3D printed from polypropylene which facilitated rapid optimization of both reactor geometry and experimental setup of the lamp housing system. To exemplify the rapidity of this approach to optimization, a Kessil LED lamp was used in the bromination of a range of toluenes in the 3D printed reactors in good yields with residence times as low as 27 s. The reaction compared favorably with the batch photochemical procedure and was able to be scaled up to a productivity of 75 mmol h⁻¹.
