Vacuum Distillation of Hydrogen Peroxide
On the Vacuum Distillation of Hydrogen Peroxide
Hydrogen peroxide is active and easy to decompose when heated, so if you want to refine it, the method of vacuum distillation is very good.
Vacuum distillation is performed in a low-pressure environment. Because the pressure is reduced, the boiling point of the liquid also decreases. Hydrogen peroxide has a high boiling point under normal pressure and is easy to decompose when heated. In a vacuum environment, its boiling point can be greatly reduced, so it can be distilled at a lower temperature to reduce the risk of decomposition.
When performing this operation, a delicate device is required. First of all, there is a closed distillation kettle to hold hydrogen peroxide and can withstand a certain negative pressure. Connect the vacuum pump to create a vacuum environment. The efficiency of the vacuum pump is related to the level of vacuum, which cannot be ignored. Furthermore, the distillation kettle needs to be equipped with a precise temperature control device, because the hydrogen peroxide is distilled within a suitable temperature range to ensure its quality and yield.
During distillation, slowly heat up, observe the hydrogen peroxide gradually turn into steam, rise up, and through the condensation device, reproduce into a liquid, and flow into the collection container. During this process, impurities are mostly left in the distillation kettle, so as to achieve the purification of hydrogen peroxide.
However, vacuum distillation of hydrogen peroxide is not without risks. If the vacuum degree is not properly controlled, or the temperature fluctuation is too large, it may lead to the decomposition of hydrogen peroxide, which may even cause danger. Therefore, the operator needs to be skilled and always pay attention to the changes of various parameters to ensure the safety and efficiency of the operation.
In summary, vacuum distillation of hydrogen peroxide is a good method of purification, but it is necessary to operate carefully and control the conditions to obtain pure hydrogen peroxide for various required domains.
