Procedure

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 methacrolein, methyl ethyl ketone, ammonia and optionally an inert gas is supplied in the reactor to proceed the gas phase catalytic reaction while maintaining the suitable reaction temperature. Thus, a reaction product gas containing 2,3,5-collidine and 2-ethyl-5-methylpyridine is obtained.
