Open Data Verified Data
light yellow powder, the goods are often made into small round particles. The melting point is about 675 ° C., the relative density is 2. 805, there are dihydrate and octahydrate. Density 2. 805G/cm3. It is easy to absorb moisture, when water or dilute acid will react to generate 02. With strong oxidation, can strongly oxidize some metals, and other flammable products placed together with the occurrence of combustion. In the molten state, almost no decomposition, but encountered Cotton, charcoal powder or aluminum powder can occur when the explosion, the use of caution. Easy to absorb moisture, and water or dilute acid, the formation of hydrogen peroxide, and violent heat. The generated hydrogen peroxide is unstable. The oxygen is released by immediate decomposition, so the oxygen is released by heating the sodium peroxide aqueous solution. Sodium peroxide with strong oxidants, such as potassium permanganate, the role also shows reducibility. It is insoluble in ethanol and can react with carbon dioxide in the air to release oxygen.

SODIUM PEROXIDE GRANULAR GR FOR ANALYSIS - Preparation Method
Open Data Verified Data
Metal sodium oxidation method molten metal sodium was preheated to 180 ° C. Or higher, and injected into the oxidation furnace at a pressure of 39. A high-speed compressed air flow of 2-44.1Pa oxidizes and Burns sodium at 300-350 ° C., and the generated sodium peroxide is gradually cooled to below 100 ° C. Through free sedimentation to obtain a sodium peroxide finished product.

SODIUM PEROXIDE GRANULAR GR FOR ANALYSIS - Application
Open Data Verified Data
can be used as oxygen supply agent, strong oxidant, with bleaching. Oxygen-increasing agent. Commonly used in the absence of air, such as mine, tunnel, diving, spacecraft, etc., can be exhaled carbon dioxide into oxygen, for people to breathe. Sodium peroxide is commonly used in industry as a bleaching agent, disinfectant, disinfectant, deodorant, oxidant, etc. Sodium peroxide is generally prepared by heating sodium metal to 300 °c in a stream of dry air that does not contain carbon dioxide. Due to its easy deliquescence and easy reaction with carbon dioxide, it must be stored in a sealed vessel.

SODIUM PEROXIDE GRANULAR GR FOR ANALYSIS - Safety
Open Data Verified Data
It has a strong oxidation, in the molten state encountered Cotton, carbon powder, aluminum powder and other reducing substances will be an explosion. Therefore, it should be safe to store and not to contact with flammable materials. With small iron drum packing, barrel seal, every 10 barrels for a box (white iron leather), each box of 50kg net weight. Moisture-absorbing agent is placed in the box, the box is covered by a solid and dry wooden box, and an iron waist or iron wire is attached. The package shall be marked with "oxidant" and "corrosive substance. It is a Class I inorganic oxidant. Should be stored in a cool, ventilated, dry warehouse. It is preferable to store it in a specialized library. The container must be sealed to avoid direct sunlight, with special attention to moisture and water resistance. When loading and unloading should be light to prevent packaging damage. Keep the items in the inventory first-in first-out, found that the package rust, should be handled in a timely manner. Regular examinations should be strengthened. Risk code: GB 5.1 class 51002. UN0.1504; IMDG CODE P. 5184, category 1. Fire, can only be covered with dry sand, fine stone, absolutely not water l toxicity and protection: strong erosion of the skin and mucous membranes, splash into the eyes will cause vision loss, and even blindness. If you accidentally splash into the eyes, you should immediately rinse with water for 15min, and then admitted to the hospital for treatment. If it is spattered on the skin, it should also be quickly rinsed with plenty of water and neutralized with boric acid water. Staff should wear protective equipment for labor protection.
