Title: Pierre Dixneuf - Innovator in Chemical Processes
Introduction
Pierre Dixneuf, based in Rennes, France, is a distinguished inventor renowned for his contributions to the field of chemical synthesis. With a record of two patents, he has made significant strides in the synthesis of saturated amino acids and the co-production of olefins and esters, reflecting his innovative spirit and technical expertise.
Latest Patents
Pierre Dixneuf holds two notable patents that showcase his inventive capabilities. The first patent is titled "Process for preparing saturated amino acids or saturated amino esters comprising a metathesis step." This method involves synthesizing a saturated long-chain α,ω-amino ester (acid) through a two-step process. The first step utilizes cross-metathesis between an acrylic first compound and a monounsaturated second compound, which includes at least one nitrile, acid, or ester trivalent function. The second step entails hydrogenation of the resultant monounsaturated nitrile ester (acid) using the same metathesis catalyst as a hydrogenation catalyst.
The second patent, "Process for co-producing olefins and esters by ethenolysis of unsaturated fats in non-aqueous ionic liquids," describes a process that reacts unsaturated fat with ethylene in a metathesis reaction using non-aqueous ionic liquids. This innovative technique produces an olefinic fraction along with a composition of monoalcohol or polyol esters, particularly from oleic sunflower seed oil and oleic rapeseed oil, enhancing the efficiency of resources in oleochemical industries.
Career Highlights
Throughout his career, Pierre Dixneuf has been associated with prestigious organizations such as the Institut Francais Du Pétrole and Arkema France. His work at these companies has been pivotal in advancing research and development in chemical processes, particularly in the synthesis and application of innovative materials.
