Abstract

Using maleic anhydride as raw material, sodium tungstate as catalyst, hydrogen peroxide as oxidizing agent, calcium hydroxide as initiator, the synthesis conditions of the best scale inhibition performance of poly epoxy succinic acid were studied by using the method of polymerization: maleic anhydride dosage was 9.8g, the catalyst sodium tungstate amount used is 0.33g, the cyclization response pH value is 4, the initiator calcium hydroxide joins the quantity is 0.5g , polymerization temperature 82 C, polymerization time 2h. The scale inhibition performance of the poly epoxy succinic acid was evaluated by atomic absorption spectrophotometry: When gathers the poly epoxy succinic acid joins the quantity is 8mg/L, the best effect of the scale inhibition rate of barium sulfate is 98%; When gathers the poly epoxy succinic acid joins the quantity is 40mg/L, the best effect of the scale inhibition rate of strontium sulfate is 90.4%.
