Addition of Pore-Forming Agents and Their Effect on the Pore Architecture and Catalytic Behavior of Shaped Zeolite-Based Catalyst Bodies.

Porous materials, such as solid catalysts, are used in various chemical reactions in industry to produce chemicals, materials, and fuels. Understanding the interplay between pore architecture and catalytic behavior is of great importance for synthesizing a better industrial-grade catalyst material. In this study, we have investigated the modification of the pore architecture of zeolite-based alumina-bound shaped catalyst bodies via the addition of different starches as pore-forming agents.

Synthesis and Complexation of a Free Germanide Bearing a Tridentate N-Heterocyclic Substituent.

The tris-N-heterocycle germanide (tmim)Ge () (tmimH = tris(3-methylindol-2-yl)methane) was synthesized by nucleophilic substitution for the tmim trianion on GeCl·dioxane. In combination with the previously reported (tmim)Si and (tmim)P analogues, it provides a convenient model for investigating the influence of the central atom on the properties of isoelectronic ligands. Complexation of the germanide (tmim)Ge to CuCl resulted in the dimeric chloro cuprate [(tmim)GeCu(μ-Cl)] , which is prone to dissociation in MeCN to form the neutral, solvated germylcopper (tmim)GeCu(NCMe).
