Isothermal decomposition of hydrogen peroxide dihydrate.
We present a new method of growing pure solid hydrogen peroxide in an ultra high vacuum environment and apply it to determine thermal stability of the dihydrate compound that forms when water and hydrogen peroxide are mixed at low temperatures. Using infrared spectroscopy and thermogravimetric analysis, we quantified the isothermal decomposition of the metastable dihydrate at 151.6 K. This deco...
متن کاملThe Decomposition of Hydrogen Peroxide by Liver Catalase
1. The velocity of decomposition of hydrogen peroxide by catalase as a function of (a) concentration of catalase, (b) concentration of hydrogen peroxide, (c) hydrogen ion concentration, (d) temperature has been studied in an attempt to correlate these variables as far as possible. It is concluded that the reaction involves primarily adsorption of hydrogen peroxide at the catalase surface. 2. Th...
متن کاملCatalytic Decomposition of Hydrogen Peroxide in the Presence of Synthesized Iron-Manganese oxide Nanocomposites via Different Methods
The special application of iron-manganese oxide nanocatalysts has been investigated in decomposition of hydrogen peroxide. In this research, iron-manganese oxide nanocomposites were synthesized by co-precipitation, sol-gel and mechanochemical methods using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared on the variou...
متن کاملControlling Non-Catalytic Decomposition of High Concentration Hydrogen Peroxide
Hydrogen peroxide (H2O2) is a strong oxidizing agent. High concentration H2O2 or High Test Peroxide (HTP) has been used extensively in the past in propulsion applications as mono and bipropellant. At low temperature, HTP can be catalytically decomposed to water and oxygen. Drawbacks to this approach include catalyst poisoning due to the presence of stabilizers in HTP, and susceptibility of the ...
متن کاملA Model for Thermal Decomposition of Hydrogen Peroxide
A one-dimensional model has been developed to investigate the thermal decomposition of rocket grade hydrogen peroxide (HP) in a stream of previously decomposed HP products. The model developed assumes steady, one-dimensional adiabatic flow and includes basic mass balances, droplet evaporation, gasphase decomposition kinetics, droplet dynamics, and control volume conservation laws. The code is a...
