HEDP

HEDP, also known as 1‑Hydroxy Ethylidene‑1,1‑Diphosphonic Acid, is an organophosphoric acid corrosion inhibitor supplied by Shandong Province Huantai County Jinlong Chemical Co., Ltd. The compound has the molecular formula C2H8O7P2 and a molecular weight of 206.02 g mol‑1. It chelates iron, copper and zinc ions, forming stable complexes that prevent scale formation and metal corrosion. The supplier lists the product as highly stable and readily soluble in water, facilitating easy dosing in industrial systems.

Typical solid‑state appearance is a white crystalline powder with a density around 1.40 g cm‑3. Solubility exceeds 100 g L‑1 at 25 °C, and a 1 % aqueous solution usually exhibits a pH of 2‑4, indicating strong acidity. The compound remains chemically stable at high pH values and resists hydrolysis under ordinary light and heat, making it suitable for high‑temperature water‑treatment loops. It can be blended with other water‑treatment chemicals without adverse reactions, a common practice in cooling‑tower and boiler chemistry programmes.

Primary end‑users include oil‑field operators, power‑plant boiler managers and manufacturers requiring corrosion control in process water. The supplier offers flexible trade terms such as FOB or CIF and accepts L/C or T/T payments, while the minimum order quantity is arranged per buyer requirement. Prospective buyers should request the latest safety data sheet and confirm any required certifications before finalising the purchase.
