N-ethylaniline

N-ethylaniline is an organic chemical compound with the molecular formula C8H11N and CAS number 103-69-5. It belongs to the family of aromatic amines, specifically an N-alkylated derivative of aniline where an ethyl group is attached to the nitrogen atom. With a molecular weight of 121.18 g/mol, this substance is classified as hazardous with acute toxicity properties and potential for organ damage upon repeated exposure.

N-ethylaniline is typically a colorless to pale yellow liquid at room temperature with a characteristic amine odor. As an aromatic amine derivative, it exhibits moderate polarity due to the nitrogen atom while maintaining hydrophobic characteristics from the benzene ring and ethyl group. The compound has limited water solubility but is generally soluble in organic solvents such as alcohols, ethers, and hydrocarbons.

N-ethylaniline serves primarily as an intermediate in organic synthesis and chemical manufacturing processes. It is commonly used in the production of dyes, pigments, and pharmaceutical intermediates. The compound also finds application in the synthesis of rubber chemicals, antioxidants, and various specialty chemicals. Its aromatic amine structure makes it valuable for creating complex organic molecules in industrial chemistry applications.

N-ethylaniline requires careful handling due to its acute toxicity classification (Acute Tox. 3). Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection when vapor exposure is possible. Work should be conducted in well-ventilated areas or under fume hoods. Avoid skin contact, inhalation, and ingestion. Emergency eyewash stations and safety showers should be readily accessible in work areas.

N-ethylaniline should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers upright and protect from physical damage. Storage areas should be equipped with appropriate spill containment measures and maintained at stable temperatures. Ensure proper labeling with hazard information and restrict access to authorized personnel only.

Immediate action is required upon contact with N-ethylaniline due to its toxicity. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult emergency services for serious exposures.

N-ethylaniline disposal must comply with local and national hazardous waste regulations due to its toxic classification. The substance cannot be disposed of in regular waste streams or sewers. Arrange disposal through licensed hazardous waste contractors who can handle toxic organic compounds. Small quantities may require specific treatment methods such as incineration at authorized facilities. Always consult local environmental authorities for specific disposal requirements.

N-ethylaniline is classified under ADR as Class 6.1 (toxic substances), Packing Group III for transportation purposes. This classification requires specific packaging standards, labeling with appropriate hazard symbols, and transport documentation. Vehicles must carry appropriate emergency equipment and drivers need proper training for hazardous materials transport. Shipping containers must meet UN specification requirements for toxic liquids.

N-ethylaniline is subject to REACH regulation requiring registration for manufacture or import in quantities above one tonne per year. The substance falls under CLP classification as Acute Tox. 3 and STOT RE 2, requiring appropriate hazard communication through safety data sheets and labeling. It is not currently listed as a SVHC (Substance of Very High Concern), but users must comply with occupational exposure limits and risk management measures.
