Cyclopentane

Cyclopentane is a cyclic saturated hydrocarbon with the molecular formula C5H10 and CAS number 287-92-3. It consists of five carbon atoms arranged in a ring structure, each bonded to two hydrogen atoms. With a molecular weight of 70.13 g/mol, cyclopentane belongs to the cycloalkane family and is classified as a flammable liquid requiring careful handling due to its fire hazard properties.

Cyclopentane is a colorless, volatile liquid at room temperature with a characteristic petroleum-like odor. It has a boiling point of approximately 49°C and is practically insoluble in water due to its non-polar nature. The compound readily dissolves in organic solvents such as alcohols, ethers, and hydrocarbons. Its low boiling point and high volatility make it easily evaporable at ambient conditions.

Cyclopentane is primarily used as a blowing agent in the production of polyurethane foams for insulation applications in refrigerators, freezers, and building materials. It serves as an environmentally friendly alternative to CFCs and HCFCs. Additionally, cyclopentane finds applications as a solvent in organic synthesis, as a component in specialty chemical formulations, and in research laboratories for various analytical and synthetic procedures.

Cyclopentane requires careful handling due to its flammable nature (Flam. Liq. 2, Danger signal word). Use appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and flame-resistant clothing. Ensure adequate ventilation to prevent vapor accumulation and eliminate all ignition sources. Handle in areas equipped with fire suppression systems and maintain grounding procedures to prevent static electricity buildup during transfer operations.

Cyclopentane must be stored in a cool, well-ventilated area away from heat sources, sparks, and open flames due to its Class 3 flammable liquid classification. Use appropriate containers made of compatible materials and ensure proper grounding. Store in areas with temperature control below 25°C and maintain adequate separation from oxidizing agents and incompatible chemicals. Implement proper inventory rotation and regular container inspection procedures.

In case of skin contact with cyclopentane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention while keeping the person conscious and calm.

Cyclopentane disposal must comply with local, national, and EU waste regulations as it is classified as hazardous waste. Contact licensed waste disposal companies specialized in flammable liquid treatment. Small quantities can be recovered through distillation for reuse when economically viable. Never dispose of cyclopentane through regular drains, sewers, or municipal waste systems. Maintain proper waste documentation and follow the European Waste Catalogue classification procedures.

Cyclopentane transport falls under ADR Class 3 (flammable liquids), Packing Group II classification. It requires appropriate UN-specification packaging with proper labeling including GHS02 pictogram and hazard identification. Transport vehicles must be equipped with appropriate safety equipment and drivers require ADR certification. Shipping documents must include proper shipping names, hazard classes, and emergency response information according to dangerous goods regulations.

Cyclopentane is subject to REACH regulation requiring registration for quantities above one tonne per year. It falls under CLP classification as Flam. Liq. 2 and Aquatic Chronic 3, requiring appropriate labeling and safety data sheets. The substance is not currently listed as SVHC (Substance of Very High Concern). Industrial users must comply with workplace exposure limits and implement appropriate risk management measures according to the supplied exposure scenarios.

Cyclopentane is available through OYSI, a specialized European distributor of technical chemicals serving industrial customers across Europe. OYSI provides cyclopentane in various packaging sizes suitable for different industrial applications, ensuring compliance with European chemical regulations. As a professional chemical distributor, OYSI offers technical support, safety documentation, and reliable supply chain management for customers requiring cyclopentane for their manufacturing processes.
