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. Usually use ethylene oxide-carbon dioxide (the ratio of the two is 90:10) or ethylene oxide-dichlorodifluoromethane mixture, mainly used for disinfection of hospitals and precision instruments. Ethylene oxide is flammable and explosive, and its chemical properties are very active. It can undergo ring-opening addition reactions with many compounds. It is not easy to transport over long distances, so it has strong regional characteristics. Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Avoid light. The storage temperature should not exceed 30°C. It should be stored separately from acids, alkalis, alcohols, and edible chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment.

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.
