💡 Commercial Applications
Ethylene oxide is a colorless gas used extensively in various commercial and industrial applications. It is commonly used as a sterilizing agent for medical equipment and supplies due to its ability to penetrate materials and kill microorganisms. Additionally, it is used in the production of various chemicals such as ethylene glycol, which is used in the manufacturing of antifreeze, polyester fibers, and plastics.
Ethylene oxide is also used in the production of ethylene oxide derivatives, such as surfactants, solvents, and antifreeze. These derivatives are utilized in various industries, including the textile, automotive, and pharmaceutical industries. In the textile industry, ethylene oxide derivatives are used as emulsifiers, dispersants, and detergents. In the automotive industry, they are used as antifreeze additives. In the pharmaceutical industry, ethylene oxide derivatives are used in drug formulations, as well as in the production of antibiotics and steroids.
In the pharmaceutical industry, ethylene oxide is used in the sterilization of pharmaceutical products and medical devices. It is particularly effective at sterilizing heat-sensitive materials that cannot be sterilized by traditional methods such as autoclaving. Ethylene oxide gas is also used in the production of certain drugs and medications, such as antibiotics, hormones, and steroids. Additionally, ethylene oxide derivatives are used as excipients in drug formulations to improve solubility, stability, and bioavailability.
⚗️ Chemical & Physical Properties
Ethylene Oxide is a colorless gas at room temperature with a slightly sweet odor. It is highly reactive and flammable, posing a potential hazard to health and safety.
With a molar mass of 44.05 g/mol and a density of 1.52 g/cm³, Ethylene Oxide is heavier than air. In comparison to common household items, Ethylene Oxide has a lower molar mass than water (18 g/mol) and a higher density than air (approximately 1.2 g/cm³).
The melting point of Ethylene Oxide is -111.3°C, and the boiling point is 10.7°C at standard atmospheric pressure. These values are significantly lower than those of water (melting point of 0°C, boiling point of 100°C), making Ethylene Oxide a volatile compound.
Ethylene Oxide is sparingly soluble in water, with a solubility of 8.3 g/L at 20°C. It has a low viscosity, allowing it to flow easily. In comparison to common household items, Ethylene Oxide is less soluble in water than salt (358 g/L at 0°C) and vinegar (1000 g/L at 20°C) and has a lower viscosity than honey.
🏭 Production & Procurement
Producing Ethylene Oxide typically involves the direct oxidation of ethylene with oxygen over a silver catalyst. This process results in the formation of Ethylene Oxide as the primary product, along with carbon dioxide and water as byproducts.
Ethylene Oxide can be procured commercially through various chemical suppliers or manufacturers. It is commonly transported in its liquid form in specialized containers, such as cylinders or tankers, due to its flammable and reactive nature.
When procuring Ethylene Oxide, safety precautions must be strictly adhered to, as it is a highly volatile and potentially hazardous substance. Specialized equipment and training are required for handling, storing, and transporting Ethylene Oxide safely.
