Overview
1,1,1,2,2,3,3-Heptafluoropropane (HFC-227ea) is a synthetic fluorinated hydrocarbon widely used in industrial and commercial applications. Its chemical stability and environmental properties make it a preferred choice in refrigeration and fire suppression systems. The compound is part of the hydrofluorocarbon (HFC) family, designed to replace ozone-depleting substances like CFCs and HCFCs. HFC-227ea is known for its non-flammability and low toxicity, which enhances its safety profile in critical applications. It is commonly used in data centers, museums, and other environments where water-based fire suppression systems could cause damage. The compound's high thermal stability ensures reliable performance under varying conditions.
Physical and Chemical Properties
HFC-227ea is a colorless, odorless gas at room temperature, with a boiling point of -16.4°C and a melting point of -131°C. Its density as a liquid is 1.41 g/cm³ at 25°C, making it heavier than air. The compound exhibits low solubility in water, which minimizes environmental impact in case of accidental release. The molecular weight of HFC-227ea is 170.03 g/mol, and its molecular formula is C3HF7. Its key chemical properties include high thermal stability and resistance to decomposition under normal conditions. These characteristics contribute to its effectiveness as a refrigerant and fire suppressant, ensuring long-term performance without degradation.
Main Applications
HFC-227ea is primarily used as a refrigerant in industrial cooling systems and as a fire suppression agent in enclosed spaces. Its non-flammable nature and rapid heat absorption make it ideal for protecting sensitive equipment in data centers, telecommunications facilities, and electrical substations. In fire suppression systems, HFC-227ea is marketed under the trade name FM-200. It extinguishes fires by removing heat and interrupting the chemical chain reaction of combustion. The compound is also used in specialty applications such as aerosol propellants and medical inhalers, where its inert properties are advantageous.
Safety and Storage
While HFC-227ea is considered safe for most applications, proper handling and storage are essential to prevent accidents. The compound should be stored in a cool, dry, well-ventilated area away from heat sources and open flames. Cylinders must be secured upright to prevent tipping and potential leakage. Exposure to high concentrations of HFC-227ea can cause dizziness or asphyxiation due to oxygen displacement. Personal protective equipment (PPE), including gloves and goggles, is recommended when handling the gas. In case of leakage, evacuate the area and ventilate thoroughly before re-entry.
B2B Procurement Guide
When procuring HFC-227ea, buyers should prioritize suppliers who provide certificates of analysis (CoA) to verify purity and compliance with industry standards such as ISO 5149 and ASTM D6806. Bulk purchases typically offer cost savings, but storage capacity and shelf life should be considered. Procurement professionals should also evaluate the supplier's logistics capabilities, including safe transportation and handling procedures. Pricing varies based on quantity and market conditions, with reference prices ranging approximately $50-$100 per kg. Long-term contracts may provide stability in volatile markets.
