| titleOfInvention | Process for preparing pyridine bases |
| abstract | A process for preparing simultaneously pyridine bases including 2-methylpyridine and 4-methylpyridine, occasionally, together with pyridine from acetaldehyde and ammonia by gas phase catalytic reaction, characterized in that the gas phase catalytic reaction is conducted in the presence of a catalyst prepared by (A) incorporating at least one compound containing at least one metal selected from the group consisting of tungsten, manganese, nickel, iron, cobalt, molybdenum, uranium, lead, silver, copper and tin into silica-alumina simultaneously with preparation of the silica-alumina, or (B) subjecting silica-alumina to ion exchange with ions of at least one metal selected from the group consisting of manganese, nickel, iron, cobalt, uranium, lead, silver, copper and tin to adsorb the ions on said silica-alumina. According to the process of the present invention, there can be obtained the desired pyridine bases in high yield, whereas formation of by-products including high boiling point pyridine derivatives is remarkably suppressed. The catalyst employed in the present process has a high resistance to the reaction atmosphere. |
