Title: Fedor Poppelsdorf: Innovator in Chemical Processes
Introduction
Fedor Poppelsdorf is a notable inventor based in Charleston, WV (US). He has made significant contributions to the field of chemical engineering, particularly in the development of processes that utilize dialkyl carbonates and improve hydrogenation reactions. With a total of 5 patents to his name, Poppelsdorf's work has implications for the production of commercially valuable products.
Latest Patents
One of Poppelsdorf's latest patents is a process for the hydrolysis of dialkyl carbonates. This innovative process allows for the utilization of dialkyl carbonates formed as by-products in the synthesis of oxalic acid esters. The method involves contacting a mixture containing the by-product with an aqueous solution of a metal carbonate under hydrolyzing conditions. This results in the conversion of the dialkyl carbonate to the corresponding alkanol, which can then be recycled for further use in the continuous process.
Another significant patent is related to the hydrogenation of alkyl oxalates. Poppelsdorf has developed an improved calcined hydrogenation catalyst shape that features an annular configuration with an open center core. This design enhances the catalyst's crush strength while maintaining catalytic activity. The catalyst shapes are particularly effective for the hydrogenation of alkyl oxalates to ethylene glycol, allowing the reaction to occur at lower temperatures and minimizing by-product formation.
