The organic process, I .e., anthraquinone process, I .e., 2-ethylanthraquinone catalytic hydrogenation, oxidation, extraction, and dilution to the desired product concentration are generally used in industry.
colorless transparent liquid. The density of 30% hydrogen peroxide at 25 °c was 1.11g/mL. Hydrogen peroxide is a very weak acid, is a strong oxidant, high concentration of hydrogen peroxide in contact with organic matter can make its combustion, and manganese dioxide will be an explosion.
The product is used as a germicidal disinfectant. Due to the high cost, it is not used much in industrial circulating water except for small systems, and the commonly used dose in small systems is about lOOmg/L. It can also be used as bleaching agent in textile printing and dyeing, paper industry and food industry.
high concentration of hydrogen peroxide solution and vapor have strong irritation and corrosive effect on human body. Content in more than 30% of the solution in contact with the skin, will make it white and tingling; Contact with the eyes can cause inflammation, and even Burns. The content of more than 50mg/kg can strongly stimulate the eyes and mucous membranes, and train the respiratory organs. The concentration limit of the short-term exposure of the human body to hydrogen peroxide vapor is 75mg/kg, and when the concentration exceeds lOOmg/kg, it is life-threatening. A large amount of water should be used to rinse the contact areas of the body. The concentration of less than 86% of industrial hydrogen peroxide, as long as the conditions meet the requirements, at room temperature is not explosive. Products with a concentration higher than 86% can only be exploded in the presence of a high energy source. The vapor-phase hydrogen peroxide can undergo an explosion under one condition. Its explosive limit concentration at atmospheric pressure is about 26 rnourn3. A gas phase containing 90% H202 is safe as long as it is kept below 115 °c. Hydrogen peroxide should be avoided from contact with certain inorganic agents and away from combustibles. Not co-stored with oxidizing substances such as organic and inorganic substances.
This product contains hydrogen peroxide (H202) should be 26.0% ~ 28.0%(g/g).
This product is a colorless clear liquid; Odorless or ozone-like odor; Oxide or reductant that is rapidly decomposed and foam, light-prone deterioration.
take 2ml of this product, accurately weigh it, put it in a 200ml bottle, dilute it to the scale with water, and shake it well; Take 10ml for precise measurement, put it in an Erlenmeyer flask, and add 20ml of dilute sulfuric acid, titrate with potassium permanganate titrant (0.02mol/L). Each 1 ml of potassium permanganate titration solution (0.02mol/L) is equivalent to 1.701mg of h202.
Disinfection antiseptic.
