Abstract
A method for producing pyridine bases which gives improved yield and comprises reacting in a gas-phase an aliphatic aldehyde, aliphatic ketone or mixture thereof with ammonia in the presence of a zeolite containing titanium and/or cobalt and silicon as zeolite constituent elements in which the atomic ratio of silicon to titanium and/or cobalt is about 5 to about 1000.
Claims8
A method for producing pyridine bases which comprises reacting in a gas-phase an aliphatic aldehyde, aliphatic ketone or mixture thereof with ammonia in the presence of a zeolite containing silicon and at least one member from the group consisting of titanium and cobalt, as zeolite constituent elements in which the atomic ratio of silicon to titanium and/or cobalt is about 5 to about 1000.
