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