Abstract:
The invention relates to a method and to a device for removing contaminants arising during the production of aliphatic or alicyclic nitric acid esters, in particular for removing contaminants from nitrated crude nitric acid esters, which nitrated crude nitric acid esters arise during the nitration of monovalent or multivalent aliphatic or alicyclic alcohols capable of nitration, after the separation of the final nitrating acid, and to a production system for nitrating monovalent or multivalent aliphatic alcohols capable of nitration with subsequent purification of the nitrated nitric acid esters.

Claim (Index 1):
An apparatus for removing impurities obtained in the preparation of aliphatic or cycloaliphatic nitric esters by removing impurities from crude nitric esters obtained in the nitration of nitratable monohydric or polyhydric aliphatic or cycloaliphatic alcohols, after removal of the residual nitrating acid, via treatment with at least one washing medium, wherein the apparatus comprises the following devices:\n (a) at least one dispersing device for contacting and emulsifying crude nitric esters to be purified and a washing medium; and, (b) arranged downstream of the dispersing device, a tube reactor for introducing the emulsion comprising the crude nitric esters to be purified and the washing medium and produced in the dispersing device, wherein the tube reactor is equipped with mixing elements for introducing additional mixing energy, so that the impurities initially present in the crude nitric esters are at least partially removed during passage of the emulsion through the tube reactor and are at least partly transferred into the washing medium and neutralized thereby during passage of the emulsion through the tube reactor; and (c) arranged downstream of the tube reactor, a separation device for separating the nitrated products which have been freed of the impurities from the washing medium.
