Latest Patents

One of Kassner's latest patents is a process for preparing quinolinic acid. This invention focuses on improved methods for manufacturing quinolinic acid by utilizing a higher concentration of reactants in the initial step. The process involves oxidizing quinoline with hydrogen peroxide in an aqueous sulfuric acid solution, in the presence of copper sulfate, to create copper quinolinate. Subsequent steps convert this copper quinolinate into quinolinic acid by treating it with alkali, which precipitates the copper as insoluble cupric oxide. The method emphasizes a thermally controllable and safe reaction, minimizing by-product formation. Another significant patent by Kassner is for preparing substituted 2-benzoylbenzoic acids. These compounds serve as intermediates for creating valuable chromogenic phthalide compounds, achieved by reacting certain substituted 3,3-diphenylphthalides with a lower alkanoic acid and water.
