Title: Elie M Chemtob: Innovator in Phosphoric Acid Technologies
Introduction
Elie M Chemtob is a notable inventor based in Claremont, CA (US). He has made significant contributions to the field of phosphoric acid technologies, holding a total of 4 patents. His work focuses on the production of aluminum fluorophosphates and alkali metal phosphates from impure phosphoric acids.
Latest Patents
Chemtob's latest patents include innovative processes for producing aluminum fluorophosphates and hydrofluoric acid (HF) from impure phosphoric acids. One of his processes involves the aging of wet process phosphoric acid containing iron, fluorine, and aluminum. This method allows for the production of a substantially calcium-free fluoroaluminum phosphate precipitate. The process includes digestion of phosphate ore matrix in recycled phosphoric acid, followed by filtration to remove insoluble residues, precipitation, and aging of the product acid. The fluoroaluminum phosphate can then be decomposed by heating to produce HF and aluminum phosphate.
