STABILITY OF HIGH STRENGTH H2O2
Abstract
Studies of low temperature (-60C. to 0C.) storage of 90% and 98% hydrogen peroxide, both commercial (stabilized) and high purity (unstabilized) in passivated Pyrex glass were completed. Conclusions are the same as earlier reported. Work was devoted to improving the electron paramagnetic resonance equipment especially by the addition of a fast closing valve, thus damping out oscillations caused by stopping the flow, and allowing observation of events in the reaction of neutral solutions of TiCl3 and H2O2 in the 1-100 m sec. time range. This system is now an excellent tool to follow the radical growth and decay in peroxide reactions. To enable direct calculations of rate constants for these reactions, optical absorption studies on the products of the reaction have been begun. Irradiated 'Teflon' FEP fluorocarbon resin containers allow storage of such hydrogen peroxide with between one-half and one-third the decomposition encountered in carefully passivated aluminum or Pyrex glass.
