摘要： The method of continuously monitoring the concentration of Grignard reactant in the "Freeport Process" cell for producing organolead compounds which comprises utilizing a reference half cell consisting of an electrode in anhydrous ether solution with a platinum group sample electrode in a solution of process Grignard reactant and adjusting upwardly the concentration of Grignard when it falls below a value of 0.02M. Also included in the invention are preferred reference half cells utilizing lead and zinc in anhydrous solvent selected from glycol diethers, such as diethylether of tetraethylene glycol (DETEG) and optionally tetrahydrofuran (THF) as a stripping solvent.
