Description
Summary:The use of active nitrogen emitted from social activities, pyridine derivatives were synthesized from ammonium carbonate and ethanol in a single reactor system. Ammonium carbonates, a promising nitrogen source recoverable from sewage water, was employed in this study. Using nickel supported on hydrotalcite (Ni/HT) as the catalyst, a 2.1% yield of pyridines and 88% selectivity for methylpyridine were achieved. Time-course analysis of reaction products revealed that nickel catalyzes the oxidation of ethanol in the initial reaction stage, followed by hydrotalcite-catalyzed ring formation. Additionally, pyridine derivatives were synthesized from other nitrogen sources, including ammonium bicarbonate, ammonium carbamate, and urea. Pyridine derivatives were also successfully synthesized from recovered ammonium bicarbonate from ammonia solution.
