Overview
Chlorobenzene is a monocyclic aromatic compound produced by chlorination of benzene. It serves as a foundational chemical in industrial organic synthesis due to its reactivity as an electrophile. The chemical is classified as a halogenated hydrocarbon and is manufactured globally at scale, with major producers in China, Europe, and North America. Industrial-grade chlorobenzene typically has a purity of ≥99%, while analytical grades may reach 99.9%. Its production is closely regulated due to environmental and health concerns, requiring compliance with standards like REACH and TSCA.
Physical and Chemical Properties
As a polar aprotic solvent, chlorobenzene exhibits moderate volatility (vapor pressure: 11.8 mmHg at 25°C) and relatively low water solubility (500 mg/L at 20°C). Its aromatic ring structure contributes to chemical stability, though it undergoes electrophilic substitution reactions. The compound's flash point is 29°C, classifying it as a flammable liquid. Notable chemical behaviors include participation in Friedel-Crafts reactions and resistance to hydrolysis. Its refractive index (1.5241 at 20°C) and dielectric constant (5.62 at 25°C) make it useful in specialized applications requiring specific solvation properties.
Main Applications
Approximately 60% of global chlorobenzene production is used to manufacture nitrochlorobenzenes, key intermediates for dyes and pesticides like DDT (now restricted). It serves as a high-boiling solvent for adhesives, paints, and degreasing formulations in metalworking. In electronics, ultra-pure grades are employed in semiconductor production. The pharmaceutical industry utilizes chlorobenzene as a building block for drugs including antihistamines. Emerging applications include its use as a heat transfer fluid in high-temperature systems, though this represents a niche market segment.
Safety and Storage
Chlorobenzene is classified as harmful (Xn) under EU regulations and requires hazard statements H226 (flammable) and H332 (harmful if inhaled). Storage must comply with NFPA 30 guidelines for flammable liquids, using approved containers (typically steel or fluorinated polyethylene) with nitrogen blanketing recommended for large quantities. Personnel handling the chemical should wear chemical-resistant gloves (nitrile or Viton), splash goggles, and respiratory protection in poorly ventilated areas. Spill containment measures include absorption with inert materials like vermiculite, never water spray due to fire risk.
B2B Procurement Guide
Industrial buyers should specify required purity (technical grade typically 98-99%, chemical pure ≥99.5%), moisture content (<0.1% preferred), and packaging (200kg steel drums or ISO tanks for bulk). Confirm supplier certifications including ISO 9001 and Responsible Care compliance. Market prices fluctuate with benzene feedstock costs and regional demand. Consider FOB versus CIF terms carefully, as chlorobenzene falls under Class 3 hazardous materials for transport. Quality verification should include GC analysis certificates for critical applications.
