摘要
聚乙二醇(木钉) 稳定了钯 nanoparticles 被准备并且在 thermoregulated 木钉双相系统适用于 1,5-cyclooctadiene (1,5 货到付款) 的选择加氢,它允许反应在一在一个阶段裂口在更低的温度跟随的高温单相。在优化反应条件下面, 1,5 货到付款和环辛烯(COE ) 的选择的变换分别地是 100 和 98% 。催化剂能被析相作用容易与产品分开并且没有明显的损失,在活动和选择为 6 再使用次。
Polyethylene glycol (PEG)-stabilized palladium nanoparticles were prepared and applied to the selective hydrogenation of 1,5- cyclooctadiene (1,5-COD) in thermoregulated PEG biphase system, which allows a reaction in a single-phase at a higher temperature followed by a phase split at a lower temperature. Under the optimized reaction conditions, the conversion of 1,5-COD and the selectivity of cyclooctene (COE) were 100 and 98%, respectively. The catalyst could be easily separated from the product by phase separation and reused for 6 times without evident loss in activity and selectivity. 2007 Yan Hua Wang.
