Title: Innovations of Pierre Coqueret in Lactam Purification

Introduction

Pierre Coqueret, an inventive mind based in Francheville, France, has made significant contributions to the field of chemical engineering through his innovative inventions. With a total of five patents to his name, Coqueret has focused on optimizing processes for the purification of lactams, a group of important organic compounds.

Latest Patents

Among his latest patents, Coqueret developed a groundbreaking process for the purification of lactams, specifically targeting the purification of ε-caprolactam obtained via the cyclizing hydrolysis of aminocapronitrile. His patented method elaborates on eliminating ammonia from the reaction medium during hydrolysis, followed by recovering the lactam in a purified form. The process involves performing distillation in the presence of a base, which results in multiple fractions: a fronts fraction containing more volatile compounds, the desired lactam fraction, and distillation tails with less volatile substances. These distillation tails are subsequently treated using various methods, such as evaporation in thin layers, allowing for the significant recovery and recycling of caprolactam back into the purification process. This innovative method enhances the recovery rates while adhering to the necessary purity standards.
