Abstract: A powdered catalyst material based on aluminum oxide, which contains at least one basic metal oxide and at least one noble metal from the platinum group of the Periodic Table of Elements in addition to aluminum oxide. The catalyst material is obtainable by loading a support material already stabilized by basic oxides by renewed impregnation with further basic oxides. After drying and calcining this post-impregnated material at temperatures below 800° C., the catalytically active noble metals are also incorporated into the support material by impregnation.

Abstract: Particulate magnesium ethoxide having a high coarse particle content can be obtained in a simple and economical manner by the present invention, which provides a process for preparing particulate magnesium ethoxide having a coarse grain content, and includes reacting metallic, optionally activated, magnesium with liquid ethanol under pressure at a temperature above 78° C.
