, 2017 本发明公开了一种由甘油制备羟基乙酸的方法，包括如下步骤：以甘油为原料，以水为溶剂，以过氧化物为氧化剂，以K类化合物或Ca类化合物为稳定剂，在光照条件下进行氧化降解反应，反应结束后经分离纯化得到所述的羟基乙酸。本发明是通过可见光或紫外光分解过氧化物产生自由基，同时用稳定剂配合，实现产物的选择性调控。本方法制备羟基乙酸的步骤简单，不需加热加压，易于控制；所用氧化剂及稳定剂的价格低廉，降解过程无需有机溶剂；在温和条件下即实现了产物的制备转化，相比现有的石油基来源的小分子原料转化法具有明显优势，是一种潜力巨大 ...

Gongye shui chuli对高级氧化工艺里氧化聚合这种有别于传统完全矿化的新型污染物转化路径做了系统综述。氧化聚合主要借助单/双电子转移来生成有机自由基或者自由基阳离子中间体，经过分子间偶联、链增长反应，把小分子污染物转变为寡聚体或聚合物，达成从“破坏型去除”到“建立型转化”。从自由基与非自由基诱导机制着手，比较了氧化聚合跟矿化路径在反应本质、氧化剂需求、产物特征方面的不同，总结了其在金属基、碳基催化体系、土壤环境中的应用情况。同时，从动力学与热力学角度说明了聚合反应路径的调控策略，还总结了聚合过程的分析方法。结果显示 ...
