application and synthesis of sodium hydroxyethylidene diphosphonate
uses hedp • na is an organic phosphonic acid scale and corrosion inhibitor, with iron, copper, zinc and other metal ions to form a stable complex, can dissolve the metal surface oxide. in 250 ℃ can still play a good corrosion and scale inhibition effect, at high ph is still very stable, easy to hydrolysis, the general conditions of light and heat is not easy to break down. acid and alkali resistance, chlorine oxidation resistance than other organic phosphonic acid (salt) is good. can be formed with metal ions in water, especially calcium ions to form six ring chelate, which has a good scale inhibition effect and a significant dissolution effect, when used in combination with other water treatment agent, showing the ideal synergistic effect the hedp • na is the most suitable for acid formulations of scale inhibitors and detergents, hedp • na is hydroxy ethylidene diphosphonic acid
