Technical parameters

Ethylene oxide is one of the simplest cyclic ethers. It is a heterocyclic compound. Its chemical formula is C2H4O. It is a toxic carcinogen and an important petrochemical product. The chemical properties of ethylene oxide are very active. It can undergo ring-opening addition reactions with many compounds and can reduce silver nitrate. It is easy to polymerize after being heated and can decompose in the presence of metal salts or oxygen. Ethylene oxide is a colorless and transparent liquid at low temperature, and a colorless gas with ether pungent odor at normal temperature. The vapor pressure of the gas is high, reaching 141kPa at 30°C. This high vapor pressure determines the epoxy Strong penetrating power during ethane fumigation and disinfection. Ethylene oxide has a bactericidal effect, is non-corrosive to metals, has no residual odor, and can kill bacteria (and its endospores), molds and fungi, so it can be used to disinfect some items and materials that cannot withstand high temperature disinfection. . Ethylene oxide is the second-generation chemical disinfectant after formaldehyde. It is still one of the best cold disinfectants. It is also the four major low-temperature sterilization technologies (low-temperature plasma, low-temperature formaldehyde steam, ethylene oxide). , Glutaraldehyde) the most important member. Ethylene oxide is also mainly used to make various other solvents (such as cellosolve, etc.), diluents, non-ionic surfactants, synthetic detergents, antifreeze, disinfectants, tougheners and plasticizers, etc. . Because ethylene oxide is flammable and has a wide explosive concentration range in the air, it is sometimes used as the fuel component of fuel gasification explosive bombs. The harmful combustion products are carbon monoxide and carbon dioxide. Most of the ethylene oxide is used to make other chemicals, mainly ethylene glycol. Ethylene oxide is flammable and explosive, and it is not easy to transport over long distances, so it has strong regional characteristics.

Application:

①Sterilization:

Ethylene oxide has a bactericidal effect, is non-corrosive to metals, has no residual odor, and can kill bacteria (and its endospores), molds and fungi, so it can be used to disinfect some items and materials that cannot withstand high temperature disinfection.

② basic chemical raw material:

Ethylene oxide is mainly used to make ethylene glycol (raw material for polyester fiber), synthetic detergents, non-ionic surfactants, antifreeze, emulsifiers, and ethylene glycol products. It is also used to produce plasticizers, Lubricants, rubber and plastics, etc.
