SYNTHESIS AND CHARACTERIZATION OF 4- AMINO-3, 5- DIBROMO- TOLUENE FROM P-TOLUIDINE
Abstract
Introduction: O-toluidine is an organic compound with the chemical formula CH3C6H4NH2. It is the most important of the three isomer toluidines. It is a colorless liquid although commercial samples are often yellowish. It is a precursor to the herbicides metolachlor and acetochlor. Toluene, formally known as toluol, is a clear, water-insoluble liquid with the typical smell of paint thinners. Materials and Methods: Chemically it is a mono-substituted benzene derivative that is one in which a single hydrogen atom from the benzene molecule has been replaced by a univalent group, in this case, CH3. Toluene reacts as a normal aromatic hydrocarbon towards electrophilic aromatic substitution. Then the mixture is filtered with the help of the filtration method and the product is further dried in a hot air oven and 4- Amino-3, 5- dibromo-toluene is formed as a brominated product. The organic layer was separated and washed once with brine and dried over sodium sulphate to give 4-bromop-toluidine in 98.7% purity. Results and Discussion: The methyl group makes it around 25 times more reactive than benzene in such reactions. The concentrated product’s melting point was 50-52°C. Conclusion: In the face of demands for sustainable and ecologically friendly organic synthesis, clean organic reaction processes which do not use harmful organic solvents are encouraged and are in great demand today.
