Title: The Innovative Contributions of Daniel Marchand
Introduction
Daniel Marchand is a notable inventor based in Jurancon, France. He has made significant contributions to the field of chemical engineering, particularly in the production of acetic acid and methyl acetate. With a total of three patents to his name, Marchand's work focuses on improving industrial processes through innovative catalytic systems.
Latest Patents
One of Marchand's latest patents is titled "Modification of the catalytic system in an industrial process for making acetic and/or methyl acetate acid." This invention describes a continuous process for manufacturing acetic acid and/or methyl acetate. It involves modifying the composition of a rhodium-based homogeneous catalyst by gradually adding an iridium compound during the continuous operation of the installation. This process allows for the transition from a rhodium-only catalyst to a rhodium and iridium catalyst without halting production, while also reducing the water content in the reaction medium.
Another significant patent is the "Process for improving the stability and/or preventing the deactivation of the catalyst during the manufacture of acetic acid and/or of methyl acetate." This process includes a reaction step involving methyl formate isomerization in a liquid phase medium, followed by a flash step for partial vaporization. The method ensures that the non-vaporized liquid fraction maintains a minimum content of formic acid and methyl formate, enhancing the stability of the catalyst used.
