Title: Jacques Benzaria: Innovator in Alkali Metal Recovery
Introduction
Jacques Benzaria is a notable inventor based in Chambly, France. He has made significant contributions to the field of chemical engineering, particularly in the recovery of alkali metals and alkaline-earth metals. With a total of 2 patents, his work has implications for both industrial processes and environmental sustainability.
Latest Patents
Benzaria's latest patents include a method for the recovery of alkali metal or alkaline-earth metal. This innovative method focuses on improving the recovery of alkali metal or alkaline-earth metal terephthalate and alkylene glycol from polyalkylene terephthalate, specifically polyethylene terephthalate (P.E.T.). The process involves saponification reactions initiated by intensive kneading of polyalkylene terephthalate and an alkaline reagent at temperatures ranging from 100°C to 200°C. The alkylene glycol is recovered in gaseous form, either through entrainment by an inert gas or by extraction under low pressure. The resulting alkaline terephthalate or alkaline-earth terephthalate is produced in solid or powder form, making it easy to store, transport, and purify.
Another significant patent is the process for the production of alkaline or alkaline-earth metal terephthalate. This process involves the reaction of an alkali metal or alkaline-earth metal hydroxide with a polyol polyterephthalate, with the optional conversion of the terephthalate into terephthalic acid. Notably, this reaction can be performed without the addition of water or with minimal water, which is beneficial for the treatment of polyol polyterephthalate waste.
