Title: Bruce A Reinhardt: Innovator in High Temperature Resistant Polyquinoxaline Resins
Introduction
Bruce A Reinhardt is a notable inventor based in Dayton, OH (US). He has made significant contributions to the field of chemistry, particularly in the development of methods for preparing tetraketones and diketones. With a total of 2 patents, his work has implications for high temperature resistant materials.
Latest Patents
Reinhardt's latest patents include the "Preparation of Tetraketones" and "Preparation of Diketones." The first patent outlines a method for preparing tetraketone precursors that are essential in producing high temperature resistant polyquinoxaline resins. This process involves oxidizing suitable diketones with a halogenating agent, such as cupric halide or hydrogen bromide, in the presence of dimethylsulfoxide. The resulting tetraketones have a specific formula where R can be hydrogen or various aryl and heterocyclic radicals.
The second patent focuses on a method for preparing diketone starting materials that are useful in synthesizing tetraketone precursors. This method involves contacting dicarboxylic acid derivatives, which lack alpha hydrogens, with an active-hydrogen compound. The reaction leads to the formation of a reaction intermediate that is subsequently hydrolyzed and decarboxylated to yield the diketone.
