초록

실리카-알루미나에 담지된 팔라듐 촉매를 제조하여 아크로레인과 암모니아로부터 피리딘과 β-피콜린의 합성반응에 사용하였다. 시간이 경과함에 따라 촉매표면에 생성된 침적물에 의하여 촉매의 활성이 크게 감소하였다. TPR 실험 결과 이 침적물은 아크로레인과 암모니아의 축합 중합에 의하여 생성됨을 알 수 있었다. 전화율과 피리딘 및 β-피콜린의 생성속도는 아크로레인의 분압이 증가할수록 감소하였다. 침적물의 양과 촉매재생 온도는 아크로레인의 분압에 따라 증가하였으나 암모니아의 분압에는 큰 영향을 받지 않았다.

Pd/SiO₂-Al₂O₃ catalysts were prepared for the synthesis of pyridine and β-picoline from acrolein and ammonia. The activity of these catalysts decreased considerably by the formation of deposits on catalyst surface during the reaction. TPR study showed that the deposits were formed by the condensation polymerization of acrolein and ammonia. The conversion and production rate of pyridine and β-picoline decreased with the partial pressure of acrolein. The amount of deposits and the regeneration temperature of spent catalysts increased with the partial pressure of acrolein but they were independent of the concentration of ammonia.
