Aniline Distributor & Supplier in kolkata India - East India Chemicals

Aniline a colorless oily liquid present in coal tar. It is used in the manufacture of dyes, drugs, and plastics, and was the basis of the earliest synthetic dyes.Phenol can be produced from aniline by reacting aniline with a mixture of sodium nitrite and hydrochloric acid to give benzene diazonium chloride, that when heated gently, gives off nitrogen to leave phenol.

vizag chemical Aniline is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine. Its main use is in the manufacture of precursors to polyurethane and other industrial chemicals. Like most volatile amines, it has the odor of rotten fish. It ignites readily, burning with a smoky flame characteristic of aromatic compounds.

Uses

The largest application of aniline is for the preparation of methylene dianiline and related compounds by condensation with formaldehyde (as discussed above). The diamines are condensed with phosgene to give methylene diphenyl diisocyanate, a precursor to urethane polymers. Other uses include rubber processing chemicals (9%), herbicides (2%), and dyes and pigments (2%). As additives to rubber, aniline derivatives such as phenylenediamines and diphenylamine, are antioxidants. Illustrative of the drugs prepared from aniline is paracetamol (acetaminophen, Tylenol). The principal use of aniline in the dye industry is as a precursor to indigo, the blue of blue jeans.

Aniline is also used at a smaller scale in the production of the intrinsically conducting polymer polyaniline.

Some early American rockets, such as the Aerobee and WAC Corporal, used Aniline with Furfuryl alcohol as a fuel with nitric acid as an oxidizer. The combination is hypergolic, igniting on contact between fuel and oxidizer. It is also dense, and can be stored for extended periods.
