Description and application:

Hydroxyethylenediphosphonic acid or OEDPK — is a colorless crystals. OEDP acid belongs to the class of diphosphonic acids, which have a high complexing ability and resistance to hydrolysis. OEDF acid is highly soluble in water, acids, alkalis, methanol and ethanol.

OEDF acid is used:

• as an inhibitor of salt deposition in the oil industry;
• as a salt deposition inhibitor for hot water systems with open water intake;
• as a complexing reagent in the chemical and textile industries;
• for the control of plant diseases in agriculture;
• as a complexing reagent, an inhibitor of salt deposition in water-circulation cooling systems of industrial enterprises and thermal power plants, in closed heat supply systems, in hot water supply systems, as well as as a reagent for washing salt deposition at various industrial facilities;
• in the process of bleaching all types of cellulose at the chelation stage in the pulp and paper industry.
