11. Ethylene oxide is isomeric with acetaldehyde and with vinyl alcohol.12. The best sterilization methods are steam, ethylene oxide gas, dry heat and chemical germicides. 13. It is also coated with magnesium stearate and finally sterilized with ethylene oxide gas. 14. Catalytic hydroformylation of ethylene oxide gives hydroxypropanal which can be hydrogenated to propane-1, 3-diol: 15. It is a cyclic tetramer of ethylene oxide which is specific for the lithium cation. 16. Williams worries that some chemicals sprayed on fruit, including ethylene oxide , may also be suspect. 17. Andersen recognized the need and the Andersen Tube was packaged and sterilized with ethylene oxide . 18. Ethylene oxide is one of the most important raw materials used in large-scale chemical production.19. Polymerization of ethylene oxide is an exothermic process. 20. The produced ethylene oxide is purified by rectification.
