摘要
Poly(aspartic acid-itaconic acid) copolymer was synthesized from aspartic acid (Asp) and itaconic acid (Ita) under microwave irradiation. The effects of microwave power, microwave irradiation time, molar ratio of itaconic acid and aspartic acid, catalyst type, catalyst and organic solvent content on copolymer yield, and the performance for inhibition of CaCO3 fouling were investigated. It was found that the product yield achieved a highest record of 95% when the amount of catalyst NaH2PO4 was 0.012 mol, the amount of organic solvent propylene carbonate was 16 mL, the molar ratio of Asp/Ita was 3: 1, the microwave output power was 1200 W and the irradiation time was 5.5 min. And the product performance for inhibition of calcium carbonate also reached a highest value of 94.38%. Structural characterization of the product showed that the product was the aspartic acid-itaconic acid copolymer.
