摘　　要：以马来海松酸和醋酸铈为原料,在氮气保护下合成马来海松酸铈,研究工艺参数对产物的影响.通过傅立叶红外光谱仪(FT-IR)、扫描电镜(SEM)、能谱仪(EDAX)和X-射线衍射仪(XRD)对产物进行分析和表征.结果表明:马来海松酸和醋酸铈反应的最佳摩尔比为1∶1.8,反应温度为60℃,时间为6 h,产率达95%以上,马来海松酸中的-COO-与Ce3+发生了化学键合,形成离子键,马来海松酸铈属于非晶态化合物.The cerium maleopimarate was synthesized from maleopimaric acid and cerium acetate under nitrogen atmosphere, the influences of the technologic parameters were investigated by the test patterns. The target product was analysised and characterized by Fourier transform infrared spectrometer（FT-IR）, Scanning electron microscope（SEM）, Energy dispersive X-ray microanalysis（EDAX） and X-ray diffraction （XRD）. The results indicate that when the mole ratio of maleopimaric acid and cerium acetate was 1 ： 1.8, reaction temperature was 60 ℃, reaction time was 6 hours, the product yield could be up to 95 %. A ionic bond was occured in the maleopimaric acid between -CO0-and Ce3＋. The cerium maleopimarate was a amorphous compound.
