A process for the production of 3-cyanopyridine by ammoxidation of 2-methyl-1,5-pentanediamine to form 3-cyanopyridine, optionally carried out as an oxidative ammonolysis process.

Processes for producing 3-cyanopyridine from 2-methyl-1,5-pentanediamine

A base synthesis process and catalyst for the preparation of pyridine or its alkylpyridine derivatives involving the catalytic reaction of one or more aldehydes and/or ketones containing from one to about five carbon atoms, with at least one reactant having more than one carbon atom, with ammonia in the gas phase. The catalyst comprises an effective amount of a large-pore zeolite having been prepared with a silica to alumina ratio of at least 15, and at least a first dimension having first channels formed by twelve-membered rings, and a second dimension having second channels formed by ten- or twelve-membered rings which intersect the first channels. The preferred zeolite is a zeolite having the structure of zeolite beta.

Pyridine base synthesis

There are provided processes for preparing quinolines by vapor phase reaction of a substituted or unsubstituted aniline base, formaldehyde and a C.sub.2 -C.sub.4 aldehyde wherein the aldehydes:aniline base molar ratio is at least 2:1. More preferred processes of the invention achieve high selectivities and yields of 8-methylquinoline, and high conversions of the aniline base.
