Ethylene oxide, also known as ethylene oxide and oxane, is the simplest cyclic ether. It is a colorless and flammable gas at room temperature and a colorless and easy-flowing liquid below 10.7°C. It has the smell of ether. Its vapor is irritating to the eyes and nasal mucosa. It is miscible with water, ethanol, alcohol, and ether. Its chemical properties are very active. It can react with many compounds to form explosive mixtures with air. The explosion limit is 3%-100% (volume). Ethylene oxide is a highly toxic substance. The allowable amount in the air is 100PPM. Inhalation of ethylene oxide can cause anesthetic poisoning. Ethylene oxide is a very important fine chemical raw material. It can be derived into a variety of fine chemical products such as ethylene glycol, non-ionic surfactants, ethanolamine, ethylene glycol ether, etc., and can be extended to produce four to five thousand products such as synthetic detergents, emulsifiers, antifreeze agents, plasticizers, lubricants, pesticides, fumigants, etc. Chemicalbook has a very wide range of applications. In the cosmetics industry, it can be used as a consistency regulator for the production of creams, toothpastes, and shaving creams. In the pharmaceutical industry, it can be used as a base for ointments, lotions, and suppositories. In the rubber industry, it can be used as a lubricant and dispersant. In the chemical fiber industry, it can be used as a polymerization monomer for dyeable polyesters. In military weapons, the main component of the BLU-82 giant bomb used by the United States during the Vietnam War was liquid ethylene oxide. The lethality of the BLU-82 giant bomb was quite huge, equivalent to a small nuclear explosion. It is widely used in medical disinfection and industrial sterilization. It is often used for gas fumigation disinfection of food, textiles, and heat-unstable drugs and surgical instruments that cannot be disinfected by other methods, such as leather, cotton products, chemical fiber fabrics, precision instruments, biological products, paper, books, documents, certain drugs, rubber products, etc.
