Oxygen scavengers or oxygen absorbers are added to enclosed packaging to help remove or decrease the level of oxygen in the package. They are used to help maintain product safety and extend shelf life. [1] There are many types of oxygen absorbers available to cover a wide array of applications. [2] [3]
It is a volatile oxygen scavenger [2] [3] and reacts in a ratio of 2.8/1 DEHA/O2. It is employed in high pressure (>70 bar) boiler systems due to a very low rate of reaction at low temperatures and pressures. Due to its volatility, it acts as an oxygen scavenger throughout the entire boiler system due to steam carryover.
