With a total of 3 patents to his name, Zumstein's work has had a considerable impact on various applications in the industry.
Latest Patents
One of Zumstein's latest patents is focused on a racemization process for optically active carboxylic acids or salts. This innovative method allows for the conversion of inactive or undesirable enantiomers of compounds, such as naproxen or ibuprofen, into usable and desirable enantiomers. The process utilizes nitrogenous bases like methylbenzylamine and involves heating an aqueous solution of optically active compounds in the presence of an alkali metal hydroxide. This approach not only enhances efficiency but also avoids the formation of amides, which can have deleterious consequences.
Another significant patent involves the production of particulate polyimide polymers. This process describes the creation of aromatic polyimides in particulate form, utilizing a homogeneous solution of polyamic acid derived from a mixture of an aromatic tetracarboxylic dianhydride and a specific compound. The method effectively prevents the agglomeration of wet polyimide polymers, which can lead to operational challenges in reactors and agitators.
