Abstract: Using urea,acetic acid and phosphorus trichloride as raw materials,ammonium salt of 1-aminocthylidenediphosphonic acid(NH4AEDP) has been synthesized with yield of 40%. The scale and corrosion inhibition tests of AEDP and HEDP(1-hydroxycthylidenediphosphonic acid) showed that AEDP is better than HEDP.

Key words: 1-Aminoethylidenediphosphosphonic acid, Synthesis, Corrosion inhibitor Scale inhibitor
