摘　　要：文章提供了一种羧酸偏酯 (简称PECA)表面活性剂的合成方法。用合成的表面活性剂作水煤浆分散剂 ,不仅能使制备出的新型水煤浆具有高浓度和高稳定性 ,而且粘度大大降低 ,水煤浆的流动特性和雾化性能得到了显著的改善。文章还对PECA样品的红外光谱图进行了分析 。A synthetic method of partial ester of carboxylic acid (PECA) surfactant was given in the paper. The synthesized products can be used as the dispersant of coal water mixture(CWM), with which the new CWM will have not only high concentration and high stability, but also have a very low viscosity, so which can improve the flow and pulverization behavior of CWM. The paper also analyzed the infrared spectra of PECA samples and studied some rules which reflect the new surfactant how to change the correlative characters of CWM.
