Ethylene Oxide sterilization is a chemical process consisting of four primary variables: gas concentration, humidity, temperature and time. Ethylene oxide is an alkylating agent that disrupts the DNA of microorganisms, which prevents them from reproducing.
The conversion from epoxyethane to the diol takes place in two stages. First the epoxide reacts with carbon dioxide to form 1,3-dioxolan-2-one (ethene carbonate): An organophosphorus compound is used as the catalyst. Ethene carbonate is then reacted with water to form ethane-1,2-diol and regenerates carbon dioxide.igure 1 Uses of ethane-1,2-diol. By far the most important uses of the diol is in the manufacture of polyesters, particularly PET (polyehylene terephthalate), used widely for clothes and for packaging. Another important use is as a coolant in engines.
