Soluble in acid, alkali and glycerol, slightly soluble in water, alkaline solution (pHl0 ~ 11), aqueous solution is unstable, easy to release active oxygen. In cold, dry air, the higher the purity of sodium perborate is more stable. Decomposition in 40 °c or humid air, and the release of oxygen. At 63 ° C, it dissolves in its own water of crystallization, and forms a viscous solid block. Above 70 °c, three crystals of water are lost to form a monohydrate. At higher temperatures, in the presence of the free base, decomposition is facilitated. With dilute acid, hydrogen peroxide is produced. When treated with concentrated sulfuric acid, oxygen and ozone are released. It is also easy to be catalyzed by other substances such as lead oxide, manganese dioxide, potassium permanganate, silver nitrate, copper oxide, cobalt oxide and platinum black. |

DISODIUMPERBORATETETRAHYDRATE - Preparation Method
Open Data Verified Data
The chemical synthesis method is to dissolve solid sodium hydroxide, mix with borax solution, adjust the concentration of the solution to 26Be with concentrated mother liquor, and remove insoluble matter by filtration after fully stirring, the partial sodium borate solution is fed into the reactor, adjusted to a suitable concentration with the mother liquor, and then a magnesium silicate stabilizer is added, and then hydrogen peroxide is added to control the flow rate of the hydrogen peroxide, and the reaction is carried out at a temperature not exceeding 35 °c. After completion of the reaction, cooling crystallization, centrifugal separation, drying, prepared sodium perborate product.
