He has made significant contributions to the field of chemical engineering, particularly in the development of innovative processes and compositions. With a total of 2 patents, his work has advanced the understanding and application of chemical reactions in industrial settings.
Latest Patents
Antonio's latest patents include a zeolite support loaded with a base material for use in the coupling of aniline and nitrobenzene. This invention provides a composition suitable for use in a reaction zone where aniline is reacted with nitrobenzene to obtain intermediates of 4-aminodiphenylamine. The solid support has interior channels with the base material loaded into the channels. The cross-sectional dimensions of the channels are designed to provide a restricted transition state, improving the selectivity of the reaction in favor of the intermediates. Additionally, the invention outlines a method for loading the base material in the solid support and a process for carrying out the reaction using this composition.
Another significant patent involves the catalytic hydrogenation of nitrobenzene to produce 4-aminodiphenylamine (4-ADPA). This method allows for the preparation of 4-ADPA by charging nitrobenzene into a reaction zone under hydrogen pressure, in the presence of a strong organic base and a catalyst for hydrogenation. The method is designed to be a one-step process, providing improved yields and selectivities. The invention emphasizes the importance of molar ratios of aniline to nitrobenzene and the choice of hydrogenation catalyst.
