PBTC 50%
SINOBIO
2-Phosphonobutane -1,2,4-Tricarboxylic Acid
(PBTC)
CAS No. 37971-36-1
Molecular Formula: C7H11O9P
Molecular weight: 270.13
Structural Formula:
Properties:
PBTC 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.
Specification:
Item | Standard |
Appearance | Index Appearance Water white to pale yellow liquid |
Active Acid % | 49.0 - 51.0 |
Phosphorous acid as PO33- % | 0.5 max |
Phosphoric acid as PO43 % | 0.2 max |
Chloride as Cl ppm | 10.0 max |
PH (1% solution) @20 °C | 1.5-2.0 |
Density (20℃),g/cm3 | 1.270 min |
Iron content (Fe ppm) | 10.0 max |

Application:
PBTC has been widely used in industry as a sequestering agent and calcium carbonate scale inhibitor for applications in industrial water treatment and industrial cleaning. It 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.
Package and Storage:
PBTC 50% : 250 kg drum or 1250 kg / IBC
Storage for one year in shady room and dry place.
