Title: Innovations of Lawrence J Jacoby
Introduction
Lawrence J Jacoby is a notable inventor based in Redding, California. He has made significant contributions to the field of chemical engineering, particularly in the separation processes of zirconium and hafnium. With a total of two patents to his name, Jacoby's work has implications for various industrial applications.
Latest Patents
Jacoby's latest patents include a zirconium-hafnium separation process. This innovative process involves separating zirconium values from hafnium values using an aqueous solution of ZrCl4 and HfCl4, which is then contacted with NH4SCN. The resultant solution is fed into a solvent extraction system containing aqueous HCl and MIBK. The process effectively separates the solvent phase containing MIBK, HSCN, hafnium thiocyanate complex, and any decomposition products of HSCN, leaving behind an aqueous phase raffinate containing NH4Cl, zirconium oxide-chloride, and low concentrations of HSCN. Additionally, Jacoby has developed a method for the removal of 3-mercapto-4-methyl-2-pentanone from zirconium and hafnium. This method prevents the formation of the compound by selectively controlling an ammonium thiocyanate-methyl isobutyl ketone regeneration system, maintaining the pH between 4 and 9, and keeping the temperature below 150°F.
