Hydrogen Peroxide Distillation
On the Method of Distillation of Hydrogen Peroxide
If you want to refine hydrogen peroxide, the method of distillation is quite crucial. Hydrogen peroxide is a chemical substance that is active and easy to decompose when heated, so you need to be cautious when distilling.
At the beginning, prepare exquisite utensils. Choose a high-quality glass still, because of its heat resistance and stable chemical properties, it can reduce the reaction with hydrogen peroxide. With a precise thermometer, it can determine the temperature and control the distillation process.
times, control the temperature of distillation. Although the boiling point of hydrogen peroxide is higher than that of water, it decomposes into water and oxygen when heated too quickly. Therefore, the heating should be slow, preferably in a water bath or an oil bath, so that the heating is uniform and the temperature rises smoothly. Usually, under appropriate pressure, the temperature is maintained at a certain range to slowly vaporize the hydrogen peroxide and avoid its violent decomposition.
Furthermore, take good care of the steam. When the hydrogen peroxide steam rises and passes through the condenser, it is necessary to ensure that the condensation effect is good. Circulate with cold water to quickly liquefy the steam and collect the pure hydrogen peroxide liquid. The collection vessel should also be clean and dry to prevent impurities from mixing and damaging its purity.
Also, pay attention to safety. Hydrogen peroxide is oxidizing, and open flames and flammable substances should be avoided in the operation room. And the distillation process is guarded by a special person to check the changes in the equipment and temperature. In case of abnormal speed, the experiment will be smooth and the personnel will be safe.
In short, the distillation of hydrogen peroxide is related to the equipment, temperature, steam treatment and safety. Do it carefully to obtain high-purity hydrogen peroxide to meet all requirements.
