Reactor for the nitration of aromatic compounds, production plant comprising said reactor and nitration process using said reactor

Abstract

The present invention relates to a reactor (1000) configured to nitrate a stoichiometric excess of an aromatic compound (1) with nitric acid (2) in the presence of sulfuric acid (3) in a continuous process under adiabatic conditions, the reactor (1000) comprising a plurality of static dispersion elements (310) arranged in a spaced-apart relationship to form a plurality of reaction chambers (400) inside the reactor (1000), wherein at least one of the reaction chambers (400) has a largest cross-sectional area (420') that is larger than that of the in flow direction preceding reaction chamber (400), and at least two of the reaction chambers (400) have an internal volume that is larger than that of the in flow direction preceding reaction chamber (400). The present invention also relates to a production plant for producing a nitrated aromatic compound, comprising the reactor (1000) according to the invention, and to a continuous process for producing a nitrated aromatic compound, comprising adiabatically reacting an aromatic compound (1) with nitric acid (2) in the presence of sulfuric acid (3) in the reactor of the invention (1000) or in the production plant of the invention.
