Organic Phosphonic Acid

2-Phosphonobutane -1,2,4-Tricarboxylic Acid (PBTCA)

          CAS No. 37971-36-1        Dequest 7000   EINECS: 253-733-5

    Molecular Formula: C7H11O9P          Molecular weight: 270.13

    Structural Formula:                SynonymsPBTC  PBTCA

    Properties:

    PBTCA has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

    Usage and Dosage:

    PBTCA is a high efficient agent as scale and corrosion inhibitor. It is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent.

    PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.

    Packing and Storage:

    Normally 250kg or 550LBS net in 200L drum, 1000kg or 2700LBS in IBC, or per customers. Storage for one year in shady room and dry place.
