摘要

发现新的环境友好型可回收光敏剂是开发未来光氧化化学应用的关键。我们在此报告了在可见光介导的单线态氧（1O2）光化学中对一组不同取代的生物基羟基蒽醌的评估。这类化合物被有效地固定在氧化铝支架上，这为从下游反应混合物中去除它们提供了一种简单的方法。此外，还对使用带有固定催化床的流动反应器的综合工艺进行了评估，并将其性能与均相条件进行了比较。

Batch to Continuous Flow Visible‐Light Photooxidations Using Alumina Supported Hydroxyanthraquinones

The discovery of new environmentally friendly recyclable photosensitizers is key to develop future applications in photooxidation chemistry. We report here the evaluation of a set of differently substituted biobased hydroxyanthraquinones in the context of visible light mediated singlet oxygen (1O2) photochemistry. This class of compounds is efficiently immobilized on alumina supports, which offers a simple way of removing them from the reaction mixture downstream. An integrated process using a flow reactor with a fixed catalytic bed is also evaluated and its performance is compared with homogeneous conditions.
