| 21. | Dr . Stumbo also developed novel sterilization operations such as ethylene oxide and vapor phase sterilization.
|
| 22. | This discovery he worked out very thoroughly in investigations of ethylene oxide and the polyethylene alcohols.
|
| 23. | This method was all but abandoned upon the discovery that ethylene oxide was a toxic carcinogen.
|
| 24. | It is used in the production of corrosion inhibitor N, N-diethylaminoethanol, by reaction with ethylene oxide.
|
| 25. | Ethylene oxide is industrially produced by direct oxidation of ethylene in the presence of silver catalyst.
|
| 26. | This was treated on the spot with carbon tetrachloride, and later with an ethylene oxide treatment.
|
| 27. | Instruments, supplies and dressings were routinely sterilized by exposure to either high-pressure steam or ethylene oxide.
|
| 28. | Some industrial gas companies may also supply related chemicals, particularly liquids such as bromine and ethylene oxide.
|
| 29. | This material comprises a sterile mixture of water-soluble alkylene oxide copolymers, derived from ethylene oxide and propylene oxide.
|
| 30. | Finally, the devices are packaged and sterilized with ethylene oxide gas, the same method that the device makers use.
