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.
