The complexity of hydrogen peroxide production technology and the dangers in the production process determine that there are certain safety hazards, especially new equipment should pay more attention to strengthening the daily safety prevention technology, and the safety control operation point of the production process is very important. Wuxi hydrogen peroxide with higher concentration (more than 10%) is used in textile, leather, paper, and wood manufacturing industries as bleaching and deodorizing agents. Hydrogen peroxide is also one of the components of hair dyes, and is also used as a material for synthesizing organic raw materials (catechol), medicine, metal surface treatment agent, polymerization initiator, etc. Can also be used as rocket propellant. Hydrogen peroxide manufacturers are mainly used for sterilization and external medical purposes, such as wound disinfection. The best ratio for testing blood: 6% hydrogen peroxide plus 0.005% methylene blue. Industrial hydrogen peroxide is another hydrogen oxide besides water. The viscosity is slightly higher than that of water, and the chemical properties are unstable. Generally, it is stored in the form of a 30% or 60% aqueous solution, and its aqueous solution is commonly known as hydrogen peroxide. Hydrogen peroxide has strong oxidizing properties and is weakly acidic. So, what are the potential risks in the hydrogen peroxide production process and how to effectively prevent accidents?
Hydrogen peroxide properties:
- Basic properties
The chemical formula of hydrogen peroxide is H2O2. Pure hydrogen peroxide is a light blue viscous liquid. It can be miscible with water in any proportion. It is a strong oxidant. The aqueous solution is commonly known as hydrogen peroxide, which is colorless, transparent and liquid.
Hydrogen peroxide itself does not burn, but it can react with combustibles to release a lot of heat and atmosphere, causing fire and explosion. When the pH value is 3.5~4.5, hydrogen peroxide is the most stable, easily decomposed in alkaline solution, and can also decompose strong light events, especially short-wave radiation. When heated to above 100°C, it begins to decompose rapidly.
It forms explosive mixtures with various organic substances such as sugar, starch, alcohols, petroleum products, etc., and explodes under the action of shock, heat or electric spark. Hydrogen peroxide, in contact with many inorganic compounds or impurities, rapidly decomposes and explodes, releasing large amounts of heat, oxygen and water vapor.
At present, my country mainly adopts the production process of hydrogen peroxide to produce anthraquinone, and it is very important how to avoid the danger of accidents when accidents occur in all aspects of production.
