Georges Sturtz

Title: **Georges Sturtz: Innovator in Phosphonic Chemistry**

Introduction

Georges Sturtz is a distinguished inventor based in Brest, France, known for his impactful contributions to the field of phosphonic chemistry. With a total of eight patents to his name, Sturtz's work focuses on developing new compounds that are critical for various industrial applications, particularly in the extraction of heavy metals.

Latest Patents

Among his latest patents, Sturtz has developed innovative diphosphonic extractants. These new diphosphonic acid diesters feature two phosphorus atoms connected by a hydrocarbon group. Each of the acid functions in the diphosphonate is esterified by a radical with at least three carbon atoms. This process involves treating a corresponding tetramethyl diphosphonate with a weak base, replacing the cations of the base with a radical R through a halide, and finally hydrolyzing the resulting mixed diphosphonate. The compounds produced are suitable for various applications, particularly in the complexing of heavy metals and the extraction of uranium.

Another significant patent from Sturtz is centered on triphosphonic esters, where three phosphorus atoms are bound to a single hydrocarbon group. These esters can have either two or four free acid functions or two salt functions and are produced by reacting an alkaline-metal derivative of a phosphite diester with a diphosphonic acid tetra-ester, followed by hydrolysis. The triphosphonic esters developed by Sturtz also find applications in the extraction of heavy metals.
