HEDP acid


Oxyethylene diphosphonic acid (OEDP) is a known complexing agent and corrosion inhibitor. OEDP is a quaternary acid with acid-base properties. In the molecule there are, in fact, acid centers and hydroxyl groups. Forms stable complexes with Fe, Cu and Zn ions.

Scope:

1) in the oil industry. As an example: in an oil preparation plant for refining, heat exchangers were cleaned after 10 days, and with the use of OEDP only after 4-5 months;

3) in agriculture OEDF is used in the production of chelated fertilizers. It is also known that OEDP – growth regulator, with pronounced antiviral and antimicrobial action. Prevents the formation of scale in drip irrigation systems;

3) due to the ability to form complexes with calcium, slows down curing; construction mixtures based on cement and gypsum;

4) in the food industry it is used as a preservative and stabilizer of food fats;

5) can act as a substitute for Trilon B (interacts with hydroxylamine) in the process of making colored paper or in the development of photographs;

6) known methods of bleaching cellulose of different types in the paper industry using OEDP.
