Hypophosphorous Acid HO2P CAS:6303-21-5 - Quality China Suppliers & Factory for Your Chemical Needs

Hypophosphoric acid, a mineral acid with the chemical formula H4P2O6, features phosphorus in a formal oxidation state of +Commonly found in solid form as dihydrate H4P2O6·2H2O, this acid is unique due to its phosphorus atoms being identical and connected by a P–P bond. As a noteworthy product of our China-based factory, we ensure the highest quality of hypophosphoric acid. Additionally, isohypophosphoric acid, a structural isomer of hypophosphoric acid, possesses one phosphorus atom bonded directly to a hydrogen atom, while also being linked to another phosphorus atom by an oxygen bridge. This configuration results in a mixed anhydride of phosphorous acid and phosphoric acid, where the phosphorus atoms exhibit +3 and +5 oxidation states respectively. For reliable suppliers of hypophosphoric acid, our factory in China is your ideal choice, providing superior products to meet your needs

    Product Introduction

    Disulfuric acid, also known as "secondary hypophosphoric acid", is a colorless oily or deliquescent crystal. It is an important product in fine chemicals. Disulfuric acid is a reducing agent and a strong monoprotic acid. Its aqueous solution is acidic and it can gradually oxidize in the air at room temperature. Contact with H2O2 will cause combustion. It will also burn when reacting vigorously with oxidants. It can decompose into highly toxic phosphine gas under high heat, even causing explosion. It is corrosive.

    ⚠️
    High reactivity with oxidants and H2O2; risk of toxic phosphine gas decomposition.
    ⚗️
    Strong monoprotic acid (K = 9×10-2) and highly effective reducing agent.
    ⚙️
    Key applications in chemical plating, esterification catalysis, and refrigerants.

    Disulfuric acid is often added to soft drinks because it is not absorbed. Therefore, it has low danger, but very concentrated disulfuric acid can harm the gastrointestinal tract. When the solid acid is heated to 130-140℃, it will undergo disproportionation decomposition into PH3 and H3PO4. Its main uses are as a reducing agent for chemical plating, to prevent the discoloration of phosphoric resin, and can also be used as a catalyst in esterification reactions, refrigerants, especially for the production of high-purity disodium disulfide. There are various preparation methods for disulfuric acid, among which the common industrial preparation methods include ion exchange resin method and electrodialysis method, etc.

    Frequently Asked Questions
    What are the primary physical properties of Disulfuric acid?
    Disulfuric acid is a colorless oily liquid or deliquescent crystal. It is a strong monoprotic acid and acts as a potent reducing agent.
    What happens when Disulfuric acid is heated?
    When solid Disulfuric acid is heated to 130-140℃, it undergoes disproportionation decomposition, resulting in the formation of PH3 (phosphine gas) and H3PO4 (phosphoric acid).
    Is Disulfuric acid dangerous to handle?
    Yes, it is corrosive and can decompose into highly toxic phosphine gas under high heat. It also poses a combustion risk when in contact with H2O2 or strong oxidants.
    What are the main industrial applications of this acid?
    It is primarily used as a reducing agent for chemical plating, a catalyst in esterification reactions, a refrigerant, and to prevent discoloration in phosphoric resins.
    How is Disulfuric acid prepared industrially?
    Common industrial preparation methods include the ion exchange resin method and the electrodialysis method.
    Can Disulfuric acid be used in food or drinks?
    It is sometimes added to soft drinks as it is not absorbed by the body, presenting low danger in diluted forms; however, high concentrations can harm the gastrointestinal tract.
