pathway can be followed for the synthesis of the desired end products. One such example is the synthesis of octyl-ethers from biomass-based glycols, which can be made either via the telomerization of 1,3-butadiene or the direct etherification of long linear alkenes. For both processes active and selective catalysts have been developed in our groups and their activity and selectivity have been investigated
人们对生物质增值的兴趣日益浓厚,引发了全球范围内寻找新的催化路线来转变交通燃料和有价值的化学物质中基于生物质的衍生物的探索。预期在大多数情况下,可以遵循一个以上的催化途径来合成所需的最终产物。一个这样的例子是由基于生物质的二醇合成辛基醚,其可以通过1,3-丁二烯的端粒化或长直链烯烃的直接醚化来进行。对于这两种方法,我们小组都开发了活性催化剂和选择性催化剂,并在无溶剂条件下研究了它们的活性和选择性。1,3-丁二烯的端粒化提供线性均相的Pd / TOMPP(TOMPP = Tris-(o-甲氧基苯基)膦)催化剂可高产率(最高80%)合成辛基醚。对于乙二醇与1-辛烯的直接醚化反应,H-Beta沸石是非常有前途的非均相催化剂,可生产支链辛基醚,收率高达80%。在这项工作中,详细说明了催化剂性能和乙二醇结构的影响,并讨论了两种催化途径的优缺点。
