Molecular Structure:

Product description: 2-Phosphonobutane-1,2,4-Tricarboxylic Acid PBTCA Molecular Formula: C7H11O9P Molecular Weight: 270.13 CAS: 37971-36-1 EINECS: 253-733-5 Appearance: Clear, colorless to pale yellow aqueous solution 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 and better than other normal organic phosphorus acid, especially under high temperature its antiscale property is far better than that of normal organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. Application: As high-efficient agent of scale and corrosion inhibitor, PBTCA is one of the widespread used and good performing products. 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.
