Overview
ME3-C2H4, commonly referred to as ethylene, is a fundamental hydrocarbon with the molecular formula C2H4. It is a colorless gas with a faint sweet and musky odor when pure. Ethylene is one of the most important organic chemicals globally, serving as a precursor to numerous industrial products. Ethylene is primarily produced through steam cracking of hydrocarbons, a process that breaks down larger molecules into smaller ones. Its significance in the chemical industry stems from its role as a building block for polymers, plastics, and other synthetic materials.
Physical and Chemical Properties
ME3-C2H4 is a highly flammable gas with a boiling point of -103.7°C and a melting point of -169.2°C. Its density is approximately 1.178 kg/m³ at standard conditions. The compound is slightly soluble in water but mixes well with most organic solvents. The double bond in ethylene makes it highly reactive, enabling it to participate in various chemical reactions, including polymerization, oxidation, and halogenation. These properties are exploited in industrial processes to produce polyethylene, ethylene oxide, and other derivatives.
Main Applications
ME3-C2H4 is predominantly used in the production of polyethylene, the most common plastic globally. It is also a key ingredient in the manufacture of ethylene oxide, ethylene glycol, and vinyl acetate, which are essential for antifreeze, polyester fibers, and adhesives, respectively. In agriculture, ethylene serves as a plant hormone to regulate fruit ripening. Additionally, it is used as a fuel in some industrial applications due to its high energy content. The versatility of ethylene underscores its critical role in modern industry.
Safety and Storage
Due to its high flammability, ME3-C2H4 must be handled with extreme caution. It should be stored in a cool, dry, well-ventilated area away from ignition sources and oxidizing agents. Proper grounding and bonding are essential to prevent static discharge. Personal protective equipment (PPE), including gloves and goggles, should be worn when handling ethylene. In case of leakage, evacuate the area and use appropriate gas detectors to monitor concentrations. Always follow local safety regulations and guidelines.
B2B Procurement Guide
When procuring ME3-C2H4, buyers should prioritize suppliers with a proven track record of safety and quality. Verify the purity levels, which typically range from 99.5% to 99.9%, depending on the application. Transportation and storage conditions should comply with international standards such as ISO and OSHA. Price negotiations should consider volume discounts, with reference prices ranging from $500 to $800 per ton. Ensure that the supplier provides proper documentation, including safety data sheets (SDS) and certificates of analysis (CoA).
