Title: The Innovative Contributions of Andrew Szalkiewicz
Introduction
Andrew Szalkiewicz is a notable inventor based in New York, NY (US). He has made significant contributions to the field of chemistry, particularly in the area of selective hydrogenation processes. With a total of 2 patents to his name, Szalkiewicz continues to push the boundaries of innovation in his field.
Latest Patents
His latest patents include methods for the selective hydrogenation of dinitrile to omega-aminonitrile. In one patent, a dinitrile is hydrogenated to an omega-aminonitrile using hydrogen in an aprotic solvent with a supported rhodium catalyst and ammonia present. The catalyst is prepared by hydrolyzing a rhodium (III) halide with strong aqueous base at elevated temperatures, followed by drying the supported rhodium hydroxide and hydrogenating the dried product. This method achieves high conversions, selectivity to aminonitrile, and catalyst recyclability. Another patent details the selective hydrogenation of dinitrile to omega-aminonitrile catalyzed by a rhodium complex. This process involves reacting a dinitrile with hydrogen in the presence of a solvent and a catalyst to form an omega-aminonitrile, such as epsilon-aminocapronitrile, with high selectivity.
