Liquified ethylene oxide
Zawartość strony
Characteristics
Ethylene oxide is obtained as a product of direct oxidation of ethylene with oxygen in the presence of silver as the catalyst. After extraction, the product is purified in the process of rectification. Ethylene oxide produced at our plant shows very high degree of purity (>99.9%.)
Ethylene oxide, due to its physicochemical properties (high reactivity, flammability, explosiveness and toxicity) requires particular care during transport, storage and handling.
Applications
Ethylene oxide is used as a precursor in production of ethylene glycols, polyols (ethylene oxide polymers and co-polymers with propylene oxide), ethanolamines, ethoxylates of fatty alcohols and alkylphenols (non-ionic detergents), as well as in a number of organic syntheses.
Properties
| Appearance |
under normal conditions ethylene oxide is a colourless gas, heavier than the air, with a distinctive odour; for practical purposes it is stored and transported as a liquid, under pressure of nitrogen. |
