Abstract:The vapor-phase condensation of aniline to diphenylamine has been studied in a downflow differential reactor at 370-426°C and under atmospheric pressure using H-151 ALCOA catalyst. An initial rate equation based on the Langmuir-Hinshelwood model, i.e. surface reaction control with a similar dual site mechanism, has been proposed:The effects of different mass transfer resistances, of longitudinal and of radial dispersion have been taken intoconsideration. The rate constant value at 404°C is I .488 X lo-' (k mol… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
