Abstract
This invention provides a three-step process for converting n-butene into high purity 1,3-butadiene, via a vinylcyclohexene intermediate. In the first step of the process, n-butene and molecular oxygen are contacted with a Group VIII metal oxide catalyst. If nitrobenzene is employed as the oxidizing agent in place of molecular oxygen then aniline is produced as a secondary product of the process.
