Abstract: HEDP was synthesized by three- step reaction from phosphrous trichloride and acetic anhydride， and the corrosion inhibition property of HEDP was investigated． The conditions of acetylation were stud- ied． The results indicated that the optimum acetylation reaction conditions were as follows: temperature was 100 ℃， the dropping rate of acetic anhydride was from fast to slow， n［( CH3 CO) 2 O］∶ n( PCl3 ) = 1 ∶ 3． The best conditions for use of HEDP were: concentration 10 mg /L， temperature 60 ℃， time 24 h． The corrosion inhibition rate and scale inhibition rate were 86． 6% and 93． 8%， respectively．

Key words:手机彩票平台 HEDP; corrosion inhibition performance; scale performance
