Propylbenzene

Propylbenzene is an aromatic hydrocarbon compound with the molecular formula C9H12 and CAS number 103-65-1. It consists of a benzene ring with a propyl group attached, having a molecular weight of 120.19 g/mol. This flammable liquid belongs to the alkylbenzene family and is classified as a hazardous substance requiring careful handling due to its flammability and potential health effects.

Propylbenzene is a colorless liquid with a characteristic aromatic odor typical of benzene derivatives. It has low water solubility but is miscible with most organic solvents including alcohols, ethers, and hydrocarbons. The compound has a relatively low vapor pressure and moderate volatility at room temperature, making it suitable for various industrial applications while requiring appropriate ventilation during use.

Propylbenzene is primarily used as an intermediate in chemical synthesis and as a solvent in various industrial processes. It serves as a precursor for the production of other aromatic compounds, including pharmaceuticals, dyes, and specialty chemicals. Additionally, it finds application in the manufacture of surfactants, polymer additives, and as a component in certain formulations requiring aromatic solvents with specific properties.

Propylbenzene requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume extraction systems to prevent inhalation exposure. Avoid contact with skin and eyes, eliminate ignition sources due to its flammable nature, and ensure proper grounding of equipment to prevent static electricity buildup during transfer operations.

Propylbenzene should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Storage areas must be equipped with appropriate fire suppression systems and spill containment measures. Keep containers away from incompatible materials such as strong oxidizing agents and ensure storage temperatures remain within recommended limits to maintain product stability and safety.

Propylbenzene contact requires immediate action: for skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting due to aspiration toxicity risk and seek immediate medical care.

Propylbenzene disposal must comply with local and national waste regulations as it is classified as hazardous waste. The substance should be collected in appropriate containers and disposed of through licensed hazardous waste treatment facilities. Incineration at high temperatures in authorized facilities is typically the preferred disposal method. Never discharge into sewers, waterways, or soil due to its environmental impact classification.

Propylbenzene is classified under ADR Class 3 (flammable liquids), Packing Group III for transportation. It requires appropriate UN-specification packaging, proper labeling with hazard pictograms, and transport documentation including safety data sheets. Vehicles must be equipped with appropriate fire extinguishing equipment, and drivers require ADR training certification. Emergency response information must accompany shipments during transport.

Propylbenzene is subject to various European regulations including REACH registration requirements and CLP classification obligations. It must be labeled with GHS pictograms (GHS02, GHS08, GHS07, GHS09) and carry the signal word 'Danger'. While not currently listed as a SVHC substance, it requires compliance with occupational exposure limits and environmental protection measures in accordance with national implementations of EU directives.
