The invention relates to a new nitration system, comprising dinitrogen pentoxide dissolved in liquid sulphur dioxide. The invention also relates to a process for nitrating aromatic compounds, where the nitration agent used is dinitrogen pentoxide dissolved in sulphur dioxide. This process is particularly favourable for nitration of aromatics that are unstable under acidic conditions. Further, this process has given very good results when nitrating aromatics that hardly have been possible to nitrate by using known nitration systems reported in the literature. |
