? Detailed Introduction of HEDP

✔ What is HEDP?

HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) is a phosphonic acid-based chelating agent and scale inhibitor widely used in industrial water treatment. It effectively prevents the formation of calcium carbonate, calcium sulfate, and other mineral scales while providing strong corrosion inhibition in metal-based systems.

✔ CAS Number & Chemical Formula:

• CAS Number: 2809-21-4

• Chemical Formula: C₂H₈O₇P₂

? Product Types & Specifications

? Applications of HEDP in Various Industries

✔ Water Treatment Industry

• Cooling Water Systems: Prevents scaling and corrosion in industrial cooling towers and air-conditioning systems.

• Boiler Water Treatment: Ensures efficient heat exchange by reducing scale deposits in boilers.

• Reverse Osmosis (RO) Membrane Protection: Extends membrane lifespan by preventing mineral deposits.

✔ Oil & Gas Industry

• Drilling Fluid Additive: Reduces scale formation in oil wells and pipelines.

• Oilfield Water Injection Systems: Enhances water flow efficiency by minimizing mineral buildup.

✔ Detergent & Cleaning Industry

• Chelating Agent in Cleaning Formulations: Improves stability and effectiveness of liquid detergents, soaps, and industrial cleaners.

• Metal Cleaning Solutions: Protects iron, steel, and copper surfaces from corrosion.

✔ Textile & Paper Industry

• Bleaching Stabilizer in Pulp & Paper Processing: Enhances hydrogen peroxide stability, reducing fiber damage.

• Fabric Processing & Dyeing: Prevents metal ion interference, ensuring uniform dyeing results.

✔ Chemical Processing Industry

• Electroplating & Metal Finishing: Reduces scale and deposits on metal surfaces.

• Pharmaceutical & Cosmetics Industry: Used as a chelating agent in personal care formulations.

? Working Principle of HEDP

1. Scale Inhibition:

• Binds with calcium, magnesium, and iron ions, preventing the formation of hard scales like calcium carbonate (CaCO₃) and calcium sulfate (CaSO₄).

2. Corrosion Prevention:

• Forms a protective film on metal surfaces, reducing oxidation and rust formation in pipelines and machinery.

3. Chelation & Dispersing Effect:

• Keeps metal ions suspended in solution, preventing deposit buildup in industrial systems.

? Production Method & Raw Materials

✔ Raw Materials Used:

• Phosphorous Acid (H₃PO₃)

• Acetic Acid (CH₃COOH) or Ethanol

• Formaldehyde (CH₂O)

✔ Production Process:

1. Reaction: Phosphorous acid reacts with acetic acid or ethanol in the presence of formaldehyde.

2. Polymerization: The mixture undergoes controlled heating to promote polymer formation.

3. Purification & Filtration: The crude HEDP is purified to remove unwanted by-products.

4. Drying & Packaging: The liquid is either sold as a solution or dried into powder form.
