geometry and linked by 1,2-ethanedisulfonate molecules. This structure is thermally stable to about 235 °C. In the second compound, discrete cationic nonanuclear bismuthate clusters interact electrostatically with trifluoromethanesulfonate anions to pack into a nearly layered assembly. The material undergoes a transformation to Bi2O3 upon loss of the triflate groups at about 385 °C. Both materials demonstrate
本文通过阴离子模板法报告了两个阳离子铋酸盐簇的合成,表征和应用。在温和的水热处理下合成了这些化合物,并通过粉末和单晶X射线衍射,红外光谱和热重分析对其进行了表征。第一种材料由阳离子六核铋酸盐簇八面体组成,并由1,2-乙烷二磺酸盐分子连接。该结构在约235°C的温度下具有热稳定性。在第二种化合物中,离散的阳离子非核铋酸盐簇与三氟甲磺酸根阴离子发生静电相互作用,堆积成几乎分层的组件。材料经历了向Bi 2 O 3的转变在约385℃失去三氟甲磺酸酯基团。两种材料都证明在这些稀有阳离子无机结构的阴离子导向组装中使用了磺酸根基团。还报道了3D八面体铋簇材料在酸性多相催化中的应用。

A liquid phase hydrogenolysis of acetal compounds such as cyclic acetals and cyclic ketals are fed to a reaction zone and reacted in the presence of a noble metal catalyst supported on a carbon or silica support to make hydroxy ether mono-hydrocarbons in high selectivity, without the necessity to use acidic co-catalysts such as phosphorus containing acids or stabilizers such as hydroquinone.
