Abstract

This paper presents our research efforts in the discovery of pioneering synthetic routes and designing low molecular-weight maleic-anhydride (MA) homopolymers and MA-n-octyl acrylamide (AAO) copolymers (YMR-series) and their application as scale inhibitors for mineral scales. Hence, the solvent-free, eco-friendly, rapid microwave-assisted method has been developed for the first time to synthesize these antiscalants with higher yield and better efficiency. The inhibition ability on the CaSO₄ and CaCO₃ scale is 100 % with a 3 ppm dosage level at pH 10.45 and temperature 70 °C.

Morphological changes of the CaCO₃ and CaSO₄ scales due to the strong inhibition action of YMR-series polymers have been studied by scanning electronic microscopy (SEM) and X-ray powder diffraction (XRD) analysis. It is also observed that the anti-scaling effect of the polymers greatly depends on the molecular weight, while MA copolymers show better inhibition efficiency compared to MA homopolymers.

马来酸酐基矿物阻垢剂的新型单锅微波合成及其应用

本文介绍了我们在发现开创性合成路线、设计低分子量马来酸酐（MA）均聚物和马来酸酐-正辛基丙烯酰胺（AAO）共聚物（YMR-系列）以及将其用作矿物垢阻垢剂方面所做的研究工作。因此，我们首次开发了无溶剂、环保、快速的微波辅助方法来合成这些产率更高、效率更高的阻垢剂。通过扫描电子显微镜（SEM）和 X 射线粉末衍射（XRD）分析，研究了 YMR 系列聚合物的强抑制作用导致的 CaCO3 和 CaSO4 鳞片的形态变化。研究还发现，聚合物的防垢效果在很大程度上取决于分子量，而与 MA 均聚物相比，MA 共聚物显示出更好的抑制效率。
