APPLICATIONS |
||
| Aromatic amines are much weaker bases than the aliphatics. One of the most important aromatic amines is aniline, a primary aromatic amine replacing one hydrogen atom of a benzene molecule with an amino group. It is a pale brown liquid at room temperature; boiling at 184 C, melting at -6 C; slightly soluble in water and freely soluble in ether and alcohol. It causes serious industrial poisoning. The substance may have effects on the blood, resulting in formation of methaemoglobin. Repeated or prolonged exposures may be carcinogenic. Commercial aniline is obtained from nitrobenzene which is prepared from benzene with nitric acid by electrophilic substitution reaction or from chlorobenzene by heating with ammonia in the presence of copper catalyst. It is also obtained as a by-product of coal tar. In commerce the term of aniline oil blue refers to the pure one while aniline oil red indicates a mixture of aniline and toluidines with equimolecular weights. Aniline is the starting material in the dye manufacturing industry. It forms aniline colors when combined with other substances, particularly chlorine or chlorates. Aromatic amines are weaker bases reacting with strong acids to form amides. Anilide is an amide derived from aniline by substitution of an acyl group for the hydrogen of NH2. Acetanilide is from acetic acid and aniline. Aniline is converted into sulfanilic acid which is the parent compound of the sulfa drugs. Aniline is also important in the manufacture of rubber-processing chemicals, explosives, plastics, antioxidants and varnishes. Amines take part in many kinds of chemical reactions and offer many industrial applications. N,N-Dimethylaniline is used as an intermediate to manufacture dyes, vanillin, tetramethyldiaminobenzophenone (white to greenish solid used as important intermediate for making dyes, pigments and photosensitizers) and other organic products. It is also used as a stabilizer for colorimetric peroxidase determination. | ||
