Abstract
Official abstract text for this publication.
The invention relates to a process for preparing aromatic amines by hydrogenation of corresponding nitroaromatics by means of hydrogen, and also an apparatus suitable for this purpose. In particular, the invention relates to a process for preparing toluenediamine (TDA) by hydrogenation of dinitrotoluene (DNT).
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus, comprising: a reactor, a driving jet nozzle at one end of the reactor, adapted for injecting a reaction mixture from a bottom region of the reactor via an external loop into the bottom region of the reactor, an inlet adapted for a nitroaromatic at one end of the reactor, an inlet adapted for hydrogen, and a measuring device adapted to detect partial or complete blocking of the inlet adapted for the nitroaromatic after improper con…
