Title: The Innovations of Charles T. Ratcliffe
Introduction
Charles T. Ratcliffe is a notable inventor based in Morristown, NJ (US). He holds a total of 9 patents that showcase his contributions to the field of chemical engineering. His work primarily focuses on the catalytic reduction of nitro aromatic compounds, which has significant implications for various industrial applications.
Latest Patents
One of Ratcliffe's latest patents involves the catalytic reduction of nitro aromatic compounds with hydrogen sulfide. This process enhances the reduction of di- or polynitro aromatic compounds by utilizing gaseous H.sub.2 S over a solid catalyst. The addition of CO gas promotes the formation of amino groups from all nitro groups in the molecule. A preferred embodiment of this invention is the reduction of 2,4- and/or 2,6-dinitrotoluene in vapor phase at 325°C over a supported iron or cobalt catalyst on an alumina support. The amino products generated from this process are particularly useful for the production of polyurethane resins.
Another significant patent by Ratcliffe is the conversion of mononitro aromatic compounds to amino compounds. This involves the hydrogenation of mononitroaromatic compounds, especially nitrobenzene and nitrotoluene, using hydrogen sulfide as a reducing agent. A titanium dioxide catalyst is employed at temperatures ranging from 200°C to 400°C and at atmospheric pressure to achieve this transformation.
