Aniline

Aniline, also known as aminobenzene or phenylamine, is an organic compound with the formula C₆H₅NH₂. It is a colorless, oily liquid that is a primary amine, meaning it has an amino group directly attached to a benzene ring. aniline has a characteristic, faintly fishy odor when pure, but older samples often acquire a yellow or reddish hue due to oxidation. It is an important industrial chemical, serving as a precursor to many other chemicals, particularly for the production of polyurethane foams, agricultural chemicals (such as herbicides and fungicides), and most notably, various dyes and pigments. The substance is also a critical component in rubber processing and the manufacturing of pharmaceuticals. The chemical reactivity of aniline arises from its nucleophilic nature, enabling it to participate in a wide range of reactions including electrophilic aromatic substitutions and reactions with carbonyl compounds, and is also moderately toxic through inhalation, ingestion, or skin contact. The chemical is important for both its industrial applications and its complex chemical properties.

Aniline meaning with examples

• The factory's effluent was carefully monitored for aniline, ensuring the environmental impact of the dye production process was minimized. Stringent regulations were in place to control the release of this potentially harmful substance into the local waterways.
• Chemists utilized aniline as a crucial starting material for synthesizing various organic compounds, including pharmaceutical ingredients. Its versatility stems from the reactivity of the amino group bonded directly to the aromatic ring. It enables diverse chemical transformations.
• During the dye manufacturing process, aniline was mixed with other reactants to form the vibrant colors of textiles and other materials. The color of the resulting products was based on the complex reactions that involved this substance, creating bright pigments.
• The researchers studied the long-term health effects of occupational exposure to aniline in a chemical plant environment. Safety protocols were in place to minimize worker's risk and promote the safe use of the substance in industries.
• In the early 20th century, the discovery of aniline dyes revolutionized the textile industry, creating a whole new range of brilliant colors and patterns. It helped create a significant shift in the products available to customers at the time.
