Latest Patents
One of his latest patents is titled "Process for the isolation of crystalline 1,3-cyclohexanedione." This invention provides a method for isolating crystalline 1,3-cyclohexanedione from the crude product formed during the catalytic gaseous phase cyclization of 5-oxohexanoic acid. The process involves adding an auxiliary component to the crude product, followed by distillation to remove reaction water and achieve a defined concentration of the auxiliary component. The resulting crystalline 1,3-cyclohexanedione is then filtered off. Another significant patent is for "8-Oxo-5,6,7,8-tetrahydro-2-quinolone and process for the preparation." This novel compound is synthesized by hydrolyzing the hydrochloride of the corresponding 8-chloro compound or the hydrobromide of the corresponding 8-bromo compound, followed by dehydrogenation.
