| Abstract: | Hydrogen peroxide containing impurities has caused a lot of explosion accidents. In this study, a simple device that using a glass vessel was made, cupric chloride was added into hydrogen peroxide, and properties of runaway reaction of hydrogen peroxide were evaluated. As a result, when copper ion exists over 0.04%, 50 g of 30%-hydrogen peroxide has caused runaway reaction. Besides, it has been confirmed that the shape of the reactor and initial temperature influence runaway reaction. |
