| Abstract: | The influences on synthesis pyridine bases over La -ZSM -5 zeolite catalysts were studied. Experimental results showed that the temperature was 400℃; the raw material ratio： formaldehyde（37% ） and acetaldehyde was 1, aldehyde and ammonia was 0.5; the space velocity was about 1200 h^-1. The total yield of pyridine bases is over 85%. The life of La - ZSM - 5 was long. It is an excellent catalyst for synthesis of pyridine bases. |
