Introduction
1. Aniline is mainly used for the preparation of methylene dianiline and related compounds by condensation with formaldehyde. The diamines are condensed with phosgene to give methylene diphenyl diisocyanate, a precursor to urethane polymers.
2. Other uses include rubber processing chemicals (9%), herbicides (2%), and dyes and pigments (2%).
3. As additives to rubber, aniline derivatives such as phenylenediamines and diphenylamine, are antioxidants.
4. The principal use of aniline in the dye industry is as a precursor to indigo, the blue of blue jeans.
