Reaktionsschritte
The process for the production of 1,5-dinitronaphthalene according to the invention is based on the direct nitration of naphthalene by nitric acid having a concentration of 72–87 wt.-% without mononitronaphthalene isolation. The washing of the reaction products with water and acetone leads to 1,5-dinitronaphthalene of high purity [≧98 wt.-%]. The acetone and nitric acid used in the process may be recovered and returned into the process. 1,8-dinitronaphthalene is produced in the process as a by-product.
