1-HYDROXYETHYLIDENEDI (PHOSPHONIC ACID) (HEDP)
HEDP is transparent sticky liquid with light yellow or colorless and density 1.34-1.48 g/cm3. It is stable in higher temperature and alkali, acid and oxidation resisting, and has a good antiscaling under 200℃,decomposed in more than 250℃. It is used as antiscaling agent of boiler, water pipeline, circle water etc. and be widely used in power plant, chemical factory and oil refinery etc.
