Using the oxidized, carboxylic acid-containing form of MPEG-750, esterification with racemic vitamin E affords a new surfactant (TPG-lite) that functions as an enabling, nanoreactor-forming amphiphile for use in many types of important reactions in synthesis. The presence of a single ester bond is suggestive of simplified treatment as a component of (eventual) reaction waste water, after recycling
使用氧化的,含羧酸的形式的MPEG-750,与外消旋维生素E酯化可得到一种新型的表面活性剂(TPG-lite),该表面活性剂可作为形成纳米反应器的两亲物,可用于合成中许多类型的重要反应。单个酯键的存在暗示了在循环后作为(最终)反应废水成分的简化处理。许多类型的反应,包括胺化,铃木-宫浦,S Ñ将Ar和其他几种元素直接与TPGS-750-M进行比较,得出的结论是,TPG-lite可以在水中充当等效的形成纳米胶束的表面活性剂。通过DLS和冷冻TEM分析收集的初步证据支持了这些实验观察。在计算机上对TPG-lite的水生毒性和致癌性进行的评估表明,它是安全使用的。
