N,N-diethylaniline

N,N-diethylaniline is an aromatic amine compound with the molecular formula C10H15N and CAS number 91-66-7. It consists of an aniline ring substituted with two ethyl groups on the nitrogen atom. With a molecular weight of 149.23 g/mol, this chemical is classified as a tertiary amine and presents significant health hazards including acute toxicity and specific target organ toxicity after repeated exposure.

N,N-diethylaniline is typically a colorless to pale yellow liquid at room temperature with a characteristic amine odor. It has limited solubility in water but is soluble in organic solvents such as ethanol and ether. The compound has a boiling point around 216°C and a density of approximately 0.93 g/cm³. It is sensitive to light and air, which can cause oxidation and darkening of the product over time.

N,N-diethylaniline is primarily used as an intermediate in the production of dyes, pharmaceuticals, and agrochemicals. It serves as a key building block in organic synthesis, particularly in the manufacture of azo dyes and various pharmaceutical compounds. The substance is also utilized in research and development applications within the chemical industry for creating specialized organic compounds and as a reagent in analytical chemistry procedures.

N,N-diethylaniline requires strict safety precautions due to its acute toxicity classification. Personnel must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin and eye contact, and ensure no eating, drinking, or smoking in work areas. Emergency eyewash stations and safety showers should be readily accessible.

N,N-diethylaniline must be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Use tightly sealed original containers made of compatible materials. Keep away from oxidizing agents, acids, and incompatible materials. Storage areas should be equipped with appropriate spill containment measures and maintained at temperatures below 25°C. Access should be restricted to authorized personnel only, with proper labeling maintained at all times.

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

N,N-diethylaniline disposal must comply with local and national hazardous waste regulations due to its toxicity and environmental impact. The substance cannot be disposed of in regular waste streams or sewers. It requires treatment by licensed hazardous waste disposal companies through appropriate methods such as controlled incineration at high temperatures. All containers must be properly labeled and documented according to waste tracking requirements before collection by authorized waste management services.

N,N-diethylaniline is classified under ADR regulations as Class 6.1 (Toxic substances), Packing Group III. Transportation requires appropriate UN specification packaging and proper hazard labeling including toxic substance markings. Vehicles must carry appropriate emergency response information and drivers need hazardous materials certification. The substance must be segregated from incompatible materials during transport and emergency response equipment should be readily available throughout the journey.

N,N-diethylaniline is subject to various chemical safety regulations including REACH registration requirements in Europe and CLP classification obligations. While not currently listed as a SVHC (Substance of Very High Concern), its Acute Tox. 3 and STOT RE 2 classifications require compliance with workplace exposure limits and safety data sheet provisions. Users must implement appropriate risk management measures and may need to notify relevant authorities depending on usage quantities and applications.
