Title: Celebrating the Innovations of Karl-Ludwig Weber

Introduction

Karl-Ludwig Weber, an accomplished inventor based in Dieburg, Germany, has made significant contributions to the field of chemistry through his innovative processes. With two notable patents to his name, Weber's work primarily focuses on the production of amines, which are crucial compounds in various chemical applications.

Latest Patents

Weber's latest inventions include a groundbreaking process for the production of primary and/or secondary amines from oxo compounds. This invention leverages catalytic imination of oxo compounds using ammonia or a primary amine, followed by hydrogenation. A distinctive feature of this process is the use of a novel imination catalyst—an organopolysiloxane containing sulphonate groups—which offers elevated activity. This method is particularly effective in synthesizing isophorone diamine from isophorone nitrile, leading to a reduced content of secondary products and an increase in yield.

Another notable patent from Weber involves the production of 3-aminoethyl-3,5,5-trimethylcyclohexyl amine, commonly known as isophorone diamine. This process initiates with the imination of isophorone nitrile and subsequently undergoes aminating hydrogenation in the presence of a fixed bed hydrogenation catalyst based on Raney cobalt. The catalyst is uniquely produced by mixing a powdery Co-containing Raney alloy with powdery cobalt, followed by sintering and activation through alkali hydroxide leaching. This innovation enhances the yield and space-time yield in the production of isophorone diamine.
