Industrial processes for manufacturing amines Original Research Article

Commercial processes for manufacturing methylamines, C2–C5 alkylamines, cyclohexylamines, and DABCO are reviewed with emphasis on technology developments that have occurred during the last fifteen years. New technologies which have been explored include zeolite-catalyzed methylamines processes, direct amination of isobutylene to produce t-butylamine, and catalytic distillation for production of butylamines and cyclohexylamine. Opportunities for further process improvements are discussed.
