Aniline (C₆H₅NH₂) is an organic compound consisting of a phenyl group attached to an amino group. It is a colorless to brownish oily liquid with a characteristic odor. Aniline is one of the most important building blocks in the chemical industry, primarily serving as a precursor to a vast array of downstream products.

Methylene Diphenyl Diisocyanate (MDI) Production: This is by far the largest application for Aniline. MDI is a key component in the manufacturing of polyurethanes, which are widely used in:

Foams: For insulation, furniture, automotive seating, and bedding.

Coatings: For protective and decorative finishes.

Adhesives: For bonding various materials.

Elastomers: For durable and flexible products.

Rubber Processing Chemicals: Energy Applications:Aniline is used in the synthesis of rubber accelerators and antioxidants, which are crucial for improving the properties and longevity of rubber products like tires, belts, and hoses.

Dyes and Pigments: It serves as a fundamental intermediate in the production of a wide range of synthetic dyes and pigments for textiles, paints, and inks.

Pharmaceuticals: Aniline derivatives are used in the synthesis of various pharmaceutical drugs and intermediates.

Agrochemicals: Used in the production of herbicides and pesticides.

Explosives: In the manufacture of certain explosive compounds.
