Abstract (en)
[origin: WO9600216A1] Improved Chichibabin aminations of pyridine bases are described which are conducted under a pressurized gas phase containing ammonia and in the presence of a selected additive which increases the reaction rate, and also in preferred processes favorably alters the isomer ratios and product yields from the aminations while benefiting product workup and recovery as well.
