Title: The Innovations of Harry W. Barnum
Introduction
Harry W. Barnum is a notable inventor based in Edison, NJ (US). He has made significant contributions to the field of chemistry and materials science, holding a total of 4 patents. His work primarily focuses on the development of advanced gellant materials for various applications.
Latest Patents
Barnum's latest patents include innovative formulations such as "Overtreated higher dialkyl dimethyl ammonium clay gellants." This invention describes the production of novel higher dialkyl dimethyl ammonium clays that exhibit superior gellant effectiveness in oxygenated organic liquids. For instance, a layered dioctadecyl dimethyl ammonium montmorillonite is prepared through the reaction of sodium montmorillonite with a 12 to 25% excess of the corresponding quaternary chloride. This overtreatment process is preferably conducted in a mixture of water and organic solvent, which helps disperse the clay and dissolve the quaternary ammonium salt. Additionally, Barnum's work on polyolefin-based greases demonstrates that these can be gelled by overtreated higher dialkyl dimethyl ammonium clays, which contain a minimum of 12% excess of the quaternary ion moiety over their ion exchange capacity.
