The direct chemical conversion of cocoa butter triglycerides, a material available as a postmanufacture waste stream from the food industry, to 1-decene by way of ethenolysis is reported. The conversion of the raw waste material was made possible by use of 1 mol % of the [RuCl(Bu-phoban)(3-phenylindenyl)] catalyst. The process has been investigated in both batch and flow conditions, where the latter approach employs a Teflon AF-2400 tube-in-tube gas-liquid membrane contactor to deliver ethylene to the reaction system. These preliminary studies culminate in a continuous processing system, which maintained a constant output over a 150 min period tested.

据报道，可可脂甘油三酯可通过乙烯分解直接化学转化为1-癸烯，可可脂甘油三酯是食品工业制造后废物流中可获得的一种材料。使用1 mol%的[RuCl(Bu-phoban)(3-苯基茚基)]催化剂可实现对这种原始废料的转化。该过程已在间歇和连续流动条件下进行了研究，后者采用聚四氟乙烯AF-2400管中管气液膜接触器将乙烯输送到反应系统中。这些初步研究最终形成了一个连续加工系统，在150分钟的测试期间保持了恒定的产量。
