HEDP.NA2 cas:7414-83-7

Sodium Hydroxyethylidene-1,1-Diphosphonic Acid HEDP·Na2 cas:7414-83-7, its full English name is Dissolve salt of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid; Chemical products, with the chemical formula C2H6O7P2 Na2, HEDP·Na2 is an organic phosphate based scale and corrosion inhibitor that can form stable complexes with various metal ions such as iron, copper, and zinc, and dissolve oxides on metal surfaces. Its appearance is colorless to slightly yellow transparent liquid or white solid powder; HEDP·Na2 is widely used in industrial circulating cooling water systems such as power, chemical, metallurgical, and fertilizer industries, as well as for scale and corrosion inhibition in medium and low pressure boilers, oilfield water injection, and oil pipelines; HEDP·Na2 can be used as a cleaning agent for metals and non metals in the textile industry, a peroxide stabilizer and fixing agent in the dyeing industry, and a complexing agent in the cyanide free electroplating industry.In general, when HEDP·Na2 is used as a scale inhibitor, its concentration is usually controlled at 2-20mg/L; When used as a corrosion inhibitor, the concentration range is generally 20-100mg/L; When used as a cleaning agent, the commonly used concentration is 1000-2000mg/L. Moreover, in practical applications, HEDP·Na2 is usually used in combination with polycarboxylate scale inhibitors and dispersants.
