Aniline solution is widely used in the production of dyes and pigments, particularly for creating vibrant colors in textiles, leather, and paper industries. It serves as a key intermediate in synthesizing methylene diphenyl diisocyanate (MDI), a crucial component in manufacturing polyurethane foams, adhesives, and coatings. Additionally, it is employed in the pharmaceutical industry to produce various drugs, including analgesics and antipyretics. In the rubber industry, aniline acts as an antioxidant and vulcanization accelerator, enhancing the durability and performance of rubber products. It is also utilized in the synthesis of herbicides and pesticides, contributing to agricultural productivity. Furthermore, aniline derivatives are used in the production of photographic chemicals and as corrosion inhibitors in metal treatment processes.
