SYNTHESIS AND CHARACTERIZATION OF 4- AMINO-3, 5- DIBROMO- TOLUENE FROM P-TOLUIDINE

Abstract

Introduction:\xa0O-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.\xa0Materials and Methods:\xa0Chemically it is a mono-substituted benzene derivative that is one in which a single hydrogen atom from the benzene molecule has been replaced by a univalent group, in this case, CH3.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.\xa0Results and Discussion:\xa0The methyl group makes it around 25 times more reactive than benzene in such reactions. The concentrated product’s melting point was 50-52°C.\xa0Conclusion:\xa0In 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.
