Potassium salt of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP·K2)
CAS No. 21089-06-5
Alias:Hydroxyethylidene diphosphonic acid potassium salt
Molecular formula:C2H6O7P2 K2
Structural formula:
HEDP·K2 is the potassium salt of HEDP. Compared with the sodium salt of HEDP, HEDP·K2 has higher solubility under neutral conditions and is an excellent inhibitor of calcium carbonate scale. HEDP·K2 is mainly used for metal corrosion inhibition, swimming pool antifouling, metal cleaning, container cleaning, iron scale control, metal pretreatment, low-pressure boiler water treatment, and circulating water treatment.
| Item | Indicator |
| Appearance | Colorless to slightly yellow transparent liquid |
| Active ingredient（HEDP）/% | 26.0～30.0 |
| Total phosphorus( PO43-)/% | 24.7～26.7 |
| pH(1%Aqueous solution) | 6.0～8.0 |
| Density（20℃）)/g·cm-3 | 1.30～1.40 |
| Fe /mg·L-1 | ≤20.0 |
HEDP·K2 is packed in plastic barrels, 30kg or 250kg per barrel, which can also be determined according to user needs. HEDP·K2 should be stored in a cool place indoors, and the storage period is ten months.
HEDP·K2, pay attention to labor protection when handling, avoid contact with skin, eyes, etc., rinse with plenty of water after contact.
