Reaction Steps
When the process of the present invention is performed in the form of a fixed bed, the catalyst of the present invention is packed in a reactor and heated to a reaction temperature. Then, the mixture of methyl ethyl ketone, formaldehyde and ammonia was allowed to proceed through the gas phase catalytic reaction while maintaining the suitable reaction temperature. Thus, a reaction product containing 2,3,5-collidine, 2,3,6-collidine and 2,3,5,6-tetramethylpyridine is obtained.
