<P>PROBLEM TO BE SOLVED: To provide a method for producing a pyridine base in a high yield, in which an aliphatic aldehyde, an aliphatic ketone or its mixture is used as a raw material. <P>SOLUTION: This method for producing the pyridine base comprises subjecting an aliphatic aldehyde, an aliphatic ketone or its mixture to a vapor-phase catalytic reaction with ammonia in the presence of a zeolite catalyst containing at least one kind selected from titanium and cobalt, and boron and silicon as constituent elements. The zeolite catalyst preferably contains further an ion and/or a compound of at least one kind of an element selected from the group consisting of elements of the groups 12-14. For example, acetaldehyde may be cited as the aliphatic aldehyde, the aliphatic ketone or its mixture. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
