摘要：

以水为溶剂,质量分数30%的过氧化氢为引发剂,NH₄Fe(SO₄)₂/V₂O₅/Cr₂O₃的复配产物为催化剂,m(马来酸酐)∶m(水)∶m(过氧化氢)=12∶11∶9的条件下,控制反应温度85℃,反应3h,一步合成了水解聚马来酸酐(HPMA)。实验结果表明,产品在投加质量浓度为0.5mg/L时,对CaCO₃的阻垢率达99.87%。

Abstract:

Hydrolyzed polymaleic anhydride (HPMA) has been synthesized in one-step under the following conditions:using a kind of home-made catalyst( the compound of NH₄FeSO₄/V₂O₅/Cr₂O₃) , H₂O as solvent and 30% of H₂O₂ as initiator, m(MA)∶m(H₂O)∶m(H₂O₂)=12∶11∶9, the reaction temperature is 85 ℃, the time of reaction is 3h. The experimental results show that the scale inhibition rate of CaCO₃ reaches 99.87% when ρ (HPMA)=0.5 mg/L.

Key words: hydrolyzed polymaleic anhydride, scale inhibitor, initiator
