N2 - 3,5-Dimethylpiperidine (DPI) is a crucial fine chemical used in the pesticide industry. The selective catalytic hydrogenation of DPI is of significant importance for efficient and sustainable production. In this study, we developed a novel, clean continuous process using a trickle bed reactor (TBR) for the hydrogenation of 3,5-dimethylpyridine (DPY) to DPI. This process offers enhanced efficiency, stability, and high-quality DPI production. Via detailed investigation of the impregnation solution pH, along with the distribution and electronic state of Ru species on the Ru/C catalyst, we have revealed the key factors for influencing catalytic performance. The findings provide valuable insights for optimizing catalyst properties, leading to the successful application of Ru/C catalysts in the continuous hydrogenation of pyridine derivatives, including DPY. This work holds significant potential for efficient large-scale continuous production of DPI and related compounds.
