Continuous process of synthesis of compounds that comprise at least one funu00c7u00e7o Amina

摘要

Continuous process of synthesis of compounds that comprise at least one funu00c7u00e7o amine. The present invention relates to a process for the manufacture of amines by hydrogenation of nitriles - compounds in the presence of a catalyst.It is more and more particularly to a manufacturing process of Diamines by continuous hydrogenation of compounds dinitrilas in the presence of a catalyst based on a metal Raney.The process according to the present invention deals with the control of molar flows of compounds, nitriles - and mass flows of catalyst in the reactor type piston of hydrogenation to minizar the formation of impurity and degradation of the activity of the catalyst.
