Description

1,2-Epoxy Ethane CAS NO 75-21-8, more commonly known as ethylene oxide, is a fundamental and highly versatile epoxide compound. It serves as a critical chemical intermediate in the synthesis of numerous industrial and consumer products, valued for its high reactivity and ability to form ethylene glycols. This product is essential for manufacturers in the chemical, pharmaceutical, and sterilization industries, where it is used to produce surfactants, solvents, and as a direct sterilizing agent for medical equipment.

Application

• Chemical Synthesis: Primary feedstock for the production of ethylene glycols (antifreeze, polyester fibers, PET resins).
• Surfactant & Detergent Manufacturing: Key intermediate in the production of ethoxylates, which are non-ionic surfactants used in soaps, detergents, and emulsifiers.
• Medical & Pharmaceutical Sterilization: Widely used as a low-temperature sterilant for heat-sensitive medical devices, surgical kits, and pharmaceutical packaging.
• Fumigation Agent: Employed for the sterilization of spices, foodstuffs, and other agricultural products to control microbial contamination.
• Production of Glycol Ethers: Used to manufacture solvents for paints, inks, and cleaning formulations.
• Polymer Industry: Serves as a monomer and chemical modifier in the production of specialty polymers and polyols for polyurethanes.
