摘要

用液氯和过氧化苯甲酰引发剂（BPO）对碳酸乙烯（EC）进行光热氯化反应，为碳-氢氯化反应提供了一条绿色途径。然而，间歇式反应器面临的挑战包括反应时间长和氯利用效率低。这些限制可以通过微通道反应器技术有效地克服。本研究开发了一种绿色、安全的环氧乙烷选择性氯化制碳酸氯乙烯（CEC）工艺。在微通道反应器中，以液氯为氯化剂，BPO为引发剂，在紫外照射下进行反应。经参数优化后，最优条件下的EC转化率为99.5%，CEC收率为84.1%。

Photothermal synergistic chlorination of ethylene carbonate in a solvent-free microchannel reactor

The photothermal chlorination of ethylene carbonate (EC) using liquid chlorine and benzoyl peroxide (BPO) initiator offers a green approach to C-H chlorination. However, batch reactors present challenges including prolonged reaction times and low chlorine utilization efficiency. These limitations may be effectively overcome through microchannel reactor technology. This study developed a green, safe process for selectively chlorinating EC to chloroethylene carbonate (CEC). In the microchannel reactor, liquid chlorine served as chlorinating agent and BPO as initiator under UV irradiation. After parameter optimization, the optimal conditions achieved 99.5% EC conversion and 84.1% CEC yield.
