Effectiveness and product safety considerations have motivated efforts to improve existing oxygen scavengers and to develop substitutes for commercial products. Improved and new products can be evaluated by properly conducted measurements of their reaction rates with oxygen. Certain product safety aspects, formation of toxic vapors and stability vis-a-vis autodecomposition can be determined by measurements of vapor concentrations under saturation conditions and by determination of autodecomposition rates respectively. These methods have been used to evaluate the suitability of solutions of hydrazine and hydrazine compounds in oxygen scavenger applications.
