| titleOfInvention | 3-methylpyridine continuous production system |
| abstract | The utility model provides a 3-methylpyridine continuous production system, which comprises a second reaction device, a second separation device, a third reaction device, a third separation device, a hydrogen supply device and an ammonia absorption tower; the 2-methyl pentanediamine takes hydrogen as a carrier and is suitable for reacting under the action of a deamination catalyst to obtain a second reaction product; the second separation device is suitable for separating 3-methylpiperidine, hydrogen and ammonia from the second reaction product; the 3-methylpiperidine takes hydrogen as a carrier and is suitable for reacting under the action of a dehydrogenation catalyst to obtain a third reaction product; a third separation means adapted to separate 3-methylpyridine and hydrogen from the third reaction product; the hydrogen is respectively returned to the hydrogen supply device for recycling, and the ammonia is recovered through the ammonia absorption tower. The utility model provides high production efficiency recycles hydrogen and ammonia to the by-product, improves energy comprehensive utilization, and the catalyst that uses in addition has higher selectivity and catalytic activity, improves the yield of 3-methylpyridine by a wide margin. |
