Product Remarks
Remarks
<div id="cke_pastebin" style="text-align: justify;">
At high temperature of 250 Deg C HEDP also resulting good corrosion and antiscaling effect. <br />
<br />
It's good resistance towards High and Low pH value makes it unique and better than that of other organophosphoric acids (salt). HEDP also resulting high chlorine oxidation tolerance properties.<br />
<br />
HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. </div>

Industrial Area
<p style="text-align: justify">
Synthesis / Manufacturing Process of HEDP:<br />
The primary raw materials used to manufacture HEDP are acetic anhydride and either phosphorus acid or phosphorus Trichloride. The phosphorus trichloride is converted to phosphorus acid within the reaction vessel, and then reacts with the acetic anhydride.</p>
<p style="text-align: justify">
Uses / Application of HEDP<br />
HEDP is used as a strong Chelating Agent for Metal Ions like Ca, Mg & Fe in water Treatment, Textile, Sugar Processing, Dye, Soaps & Detergents.<br />
<br />
Properties :<br />
<br />
HEDP is a 60% active aqueous solution and is part of the Biphosphonic Acid Group. It is highly water soluble and stable under harsh conditions, which makes it ideal for water treatment. The main uses in the water treatment industry are, reverse osmosis formulation, cooling water treatment, boiler water treatment, swimming pools, scale and corrosion inhibitor.<br />
</p>
<p style="text-align: justify;">
<strong>Handling</strong> : HEDP 60% is slightly toxic by ingestion, practically non-toxic on dermal application, moderately irritating to the skin and corrosive to the eyes. Care should be taken to avoid contact with skin and eyes. In case of contact, flush the affected area with plenty of water. Goggles and rubber gloves should be used at all times when working with the concentrated material.<br />
<br />
<strong>Storage</strong> : Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Over time, pressure may increase causing containers to burst Handle and open container with care.</p>
