| Abstract: | The preparation of p nitrobenzoic acid, a fine chemical product with a high added va lue , from waste polystyrene by nitration oxidation was studied. The affecting factors such as concentration and dosage of nitric acid, reaction pressure, reaction time and catalyst dose were investigated. The yield and the purity of p nitrobenzoic acid were 52% and 99% respectively under the optimum conditions. |
