The synthesis route of Potassium salt of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP•K2) is typically achieved through the neutralization reaction of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) with potassium hydroxide (KOH) in an aqueous solution. The resulting mixture is then spray-dried to obtain the final product.

Frequently Asked Questions

What is HEDP Kx?
HEDP·Kx is the potassium salt of HEDP. Compared with the sodium salt of HEDP, HEDP·Kx has higher solubility under neutral conditions and is an excellent inhibitor of calcium carbonate scale. HEDP·Kx is mainly used for metal corrosion inhibition, swimming pool antifouling, and also for metal cleaning, container cleaning, iron fouling control, metal pretreatment, low pressure boiler water treatment, circulating water treatment.
