Synthesis of Anhydride-2-Acrylamido-2-Methyl-Propane Sulfonic Acid Copolymers and Its Scale Inhibition Performances Toward Calcium Sulfate
摘要
Abstract
Some kinds of new scale inhibitors have been used in production for the inhibition of the precipita?tion of calcium sulfate in industrial equipment. The copolymer maleic anhydride-2-acrylamido-2-methyl-propane sulfonic acid (PMA-PAMPS) were synthesized by using maleic anhydride (MA) and 2-acrylamido-2-meth?yl-propane sulfonic acid(AMPS)as raw materials and potassium persulfate as initiator.The copolymer was char?acterized by FT-IR and elemental analysis, and the scale inhibition performance of it was analyzed at different concentrations and temperatures. The results show that the scale inhibition rate of PMA-PAMPS is 92.09% after 3 mg/L of the scale inhibitors was added into the solution with the mass concentration of calcium of 1.510 g/L at 60 ℃. The PMA-PAMPS has good scale inhibition performance even at 60 ℃-80 ℃. The scan electron micro?scope of the sample crystals also demonstrates that the polymer has higher scale inhibition efficiency.关键词
