Latest Patents
One of his latest patents is titled "Process for recovery of pyridine-2,3-dicarboxylic acid." This process involves recovering pyridine-2,3-dicarboxylic acid from a process stream during its preparation. The method utilizes nanofiltration at a pH higher than 4.5, with a preferred pH range between 7 and 9, and a concentration factor in nanofiltration greater than 3. The process stream is typically formed by the mother liquor obtained from the oxidation of a suitable quinoline or 2,3-lutidine, followed by the separation of solid material.
Another significant patent by Maas is "Process for the preparation of dibenzylamine." This innovative process involves the hydrogenation of benzaldehyde in the presence of ammonia and a palladium-containing catalyst. The method allows for the preparation of dibenzylamine with high selectivity and complete conversion of benzaldehyde in a relatively short reaction time, making it commercially attractive. A palladium-carbon catalyst is preferably used in this process.
