Key Properties and ApplicationsIsopentane boasts remarkable volatility and flammability, making it an essential component in industrial and laboratory settings. Common applications include its use in the production of polyurethane foams as a blowing agent, as a solvent, and as a refrigerant. With rapid evaporation and effectiveness in chemical processing, isopentane is also employed in calibration standards and as a chemical intermediate. Its purity, low boiling point, and compatibility with organic solvents provide significant practical benefits across diverse industries.
Safe Storage and Handling GuidelinesProper storage of isopentane is crucial for safety due to its low flash point and high volatility. This chemical should be kept in cool, well-ventilated areas, far from heat sources, sparks, or open flames. Specialized sealed containers, drums, or tankers ensure containment. Adhering to recommended storage practices preserves product stability and shelf life, which is up to 24 months. Always use appropriate protective gear to minimize the risk of inhalation or accidental contact.
Regulatory and Environmental ConsiderationsIsopentane has a UN Number 1265 and is classified as a flammable liquid (Hazard Class 3, Packing Group II). Environmental care is vital, as it is a volatile organic compound and a potential groundwater contaminant. Safe handling, transport, and storage are necessary to minimize risks. Compliance with international transport and packaging regulations is mandatory for distributors, exporters, and importers.
FAQs of Isopentane:
