Vol.2, No.3 (2009), 688-690 LARGE SCALE PROCESS OF MESALAMINE Neti Srinivasan and Jaydeepkumar Lilakar 689 Preparation of 2-Hydroxy-5-nitro benzoic acid 3 To a stirred solution of potassium hydroxide (70 kg, 1250 mol) and water (250 L) was added 2 (50 kg.The most of commercial benzoic acid is produced by the reaction of toluene with oxygen at temperatures around 200 C in the liquid phase and in the presence of cobalt and manganese salts as catalysts. It can be prepared also by the oxidation of benzene with concentrated sulphuric acid or carbon dioxide in the presence of catalysts. Other methods.
The mechanism in figure 1 was to combined 4-aminobenzoic acid and ethanol in a reflux reaction with the addition of sulphuric acid as a catalyst to produce the product. Figure 1 Method: In week one of the experiment, 4-aminobenzoic acid (3.0g), methylated spirits (20cm 3 ) and concentrated sulphuric acid (3.0ml) was added to a dry round bottom flask (100cm 3 ).
