PROCESS FOR PREPARING QUINOLINE BASES

摘要

There are provided processes for preparing quinolines by vapor phase reaction of a substituted or unsubstituted aniline base, formaldehyde and a C2-C4 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.
