摘要：

以绿色化学为基础,研究了水解聚马来酸酐 (HPMA)的绿色合成工艺。结果表明,以H₂O₂ 替代过氧化苯甲酰 (BPO)引发剂,用水替代有机溶剂,通过一釜多步串联反应,可实现HPMA的清洁生产,彻底消除传统工艺对环境的污染。采用该工艺合成的产品溴值低、相对分子质量高、阻垢性能好,达到了国家优等品标准。

Abstract:

Based on green chemistry,the cleaner production of HPMA(hydrolyzed polymaleic anhydride) has been studied. The results show that the aim is achieved by using multistage series reactions with H₂O₂ to replace initiating agent BPO and water to replace organic solvent in a still. It avoids the environmental pollution caused by the traditional techniques. The products made by this method have low bromine-value,high molecular weight,excellent scale-inhibition,and reaches the class-product national standard.

Key words: hydrolyzed polymaleic anhydride, scale inhibitor, cleaner production techniques
