Explodability and detonability of mixtures of hydrogen peroxide and organic matter
other
The explosive properties of mixtures of hydrogen peroxide and isopropanol were determined The mixtures appear to detonate in a well-defined range of concentrations and show extremely fast reactions in an adjacent range of concentrations if initiated by shock wave stimuli. The upper boundary of organic matter concentrations at which initiation can be initiated appears to depend on temperature by margins of about 10 to 15%. The lower boundary is hardly affected by temperature
Initiation by exposure to heat may lead to detonation as well. This implies that venting may not be sufficient to reduce the hazard at these concentrations. The range of concentrations at which detonable properties were observed upon initiation by thermal stimuli is similar to the ranges observed with shock stimuli The test (SCB) and test procedure applied in testing with thermal stimuli appear to be very suitable for this type of testing.
