2-Phosphonobutane -1,2,4-Tricarboxylic Acid (PBTCA)
Molecular Formula: C7H11O9P Molecular weight: 270.13
Dequest 7000
Structural Formula:
Properties:
This product has structural features of both phosphonic acid and carboxylic acid group, which enable its excellent antiscale corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can also improve the solubility of zinc salt, has good chlorine oxidation resistance and good composite synergy.

Usage:
PTBCA is the widely used high efficient agent as composite antiscale corrosion inhibitor, it is also the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as antiscale corrosion inhibitor, especially suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkali and high index of condense multiples, it is used as chelating agent and metal detergent in lavation fields.
PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other water treatment agents.
