| 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 studied.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（CH3CO）2O] ∶ 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. |
