Aniline is widely used in the production of polyurethane foams, which are essential in manufacturing mattresses, furniture cushions, and insulation materials. It serves as a precursor in the synthesis of methylene diphenyl diisocyanate (MDI), a key component in polyurethane production. Additionally, aniline is employed in the dye industry for creating various synthetic dyes, including indigo and azo dyes, which are used in textiles, leather, and paper. It also plays a role in the production of rubber chemicals, such as antioxidants and vulcanization accelerators, enhancing the durability and performance of rubber products. Furthermore, aniline is utilized in the pharmaceutical industry for synthesizing drugs like paracetamol and sulfa drugs, contributing to medical treatments. Its applications extend to agrochemicals, where it is used in the production of herbicides and pesticides, aiding in crop protection and agricultural productivity.
