In both Sn2 and E2 both the leaving group and the … WebEthylene oxide (EO) is the most commonly used agent in chemical sterilization. Because it is a gas, it rapidly penetrates packaging and items to be sterilized at temperatures tolerated by almost all materials. However, its use is limited by the size of the equipment, the time requirement, and concerns about toxicity.
