Title: Lise Layeillon: Innovator in Acetic Acid Production
Introduction
Lise Layeillon is a prominent inventor based in Lacq, France. She 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 her name, Layeillon's work has advanced the methods used in these important chemical processes.
Latest Patents
Layeillon's latest patents include a method for preparing acetic acid and/or methyl acetate in the presence of iridium and platinum. This invention relates to a process for the preparation of these chemicals in the liquid phase through the carbonylation of methanol and/or the isomerization of methyl formate. The process utilizes a homogeneous catalyst system that includes iridium, a halogen-containing promoter, and carbon monoxide.
Another notable patent focuses on improving the stability and preventing the deactivation of the catalyst during the manufacture of acetic acid and/or methyl acetate. This process involves a first reaction step where a methyl formate isomerization reaction is conducted in a liquid phase medium, followed by a flash step that partially vaporizes the reaction medium. The resulting non-vaporized liquid fraction maintains a content of formic acid and methyl formate at least equal to 1% by weight.
