在这方面的贡献，沸石分子筛的结构参数的影响，在乙醇转化为1，3-丁二烯进行了研究。因此，合成了两个材料系列。首先，沸石-β已经被脱硅以实现分级结构。这种沸石太不稳定了。然而，进行的反应证实，结晶度，微孔结构和转化率之间存在联系。第二系列包括常规和中孔LTA。我们合成了类似的材料，平均孔宽分别为5.9和7.0 nm。在所考虑的反应中使用那些导致转化率随孔径的显著增加。
In this contribution, the influence of structural parameters of zeolites in the transformation of ethanol into 1,3-butadiene has been investigated. Therefore, two material series were synthesized. First, a zeolite-β has been desilicated to achieve a hierarchical structure. This zeolite turned out being too unstable. Nevertheless conducted reactions confirmed, that there is a connection between crystallinity, microporous structure and conversion. The second series comprised conventional and mesoporous LTAs. We synthesized similar materials with mean pore widths of 5.9 and 7.0 nm, respectively. Using those in the considered reaction led to a significant increase of the conversion with the pore size.
