The reaction is very interesting and is a very good way to practice lab skills. Nitronium ions attack on aromatic rings, majorly at ortho and para positions which further form ortho and para-products. Air is continually fed to the reactor and intimately mixed with the toluene charge and the reactor is maintained at a pressure of about pounds per square inch. The separated benzoic acid can be purified by washing the recovered product with fresh toluene and again separating the precipitated benzoic acid. This is the common yield for this reaction. you are sving my life thank y but just one question , the KOH comes from where ? = 0 g of water = 1%. acid is formed. The benzoic acid product thus obtained is relatively stable to prolonged periods at elevated temperatures. It could also be due to impurities From the melting point value, it can be deduced that the product is o-toluic acid, as the melting 5. One of the simplest elements in the class of toluenes is toluene, which is benzene with one methyl substituent. Appearance: Colourless liquid with a benzene-like odour
