Method for dinitration of aromatic compounds |
| abstract |
(57) Abstract: The object of the present invention is to minimize the inhibition of mass transfer and the formation of by-products during a very rapid first nitration, and to repeatedly redisperse an aggregation prone emulsion. The aim is to improve the multiple nitration of aromatics so as to maintain a larger interface and achieve high space-time yields. SOLUTION: The continuous dinitration method is carried out in a single apparatus under an adiabatic condition with an emulsion as a reaction medium, and 1.3 to 3. 5 mol of HNO 3 are charged as a nitronium-containing solution and an aggregation-prone emulsion is maintained by multiple dispersions. At least 20% of the total HNO 3 can be used in the first dispersion of the liquid stream, which takes less than 1 second to make the emulsion. However, preferably the nitronium-containing solution is fully used in the first dispersion of both phases. |
