摘　　要：利用液相反应法成功制备了马来松香/CaO有机无机杂化材料。通过正交试验法对制备工艺进行探讨,研究各工艺参数对产率的影响。结果表明：温度338K、反应时间30min、Ca（NO3）2的初始浓度0.215mol/L时产率最高。采用傅立叶红外光谱、带能谱仪（EDAX）的扫描电镜（SEM）和X射线衍射（XRD）等技术对杂化材料进行了分析和表征。结果表明,利用该方法制得的马来松香/CaO杂化材料属于晶态化合物,产物中的—COO-与Ca2＋发生了化学键合;马来松香钠和Ca（NO3）2物质的量之比影响马来松香/CaO杂化材料的纯度,制备纯的马来松香/CaO杂化材料,马来松香钠和Ca（NO3）2物质的量之比应该控制在1∶1.2～1∶1.5之间。The maleated rosin/CaO hybrid material was synthesized by liquid-phase method.The process conditions were investigated by orthogonal experiment. The results showed that the condition for the optimum yield was as follows： temperature 338 K, reaction time 30 min, Ca（NO3）2 initial concentration 0.215 mol/L. Maleated rosin/CaO hybrid material was characterized by Fourier transform infrared spectrometry（FT-IR）, scanning electron microscopy（SEM）, energy dispersive X-ray microanalysis（EDAX） and X-ray diffraction（XRD）. The results reveal that the obtained maleated rosin/CaO is crystalline compound, and chemical bonding occurs between —COO-and Ca2＋. The purity of the maleated rosin/CaO hybrid material was affected by the amount ratio of sodium maleated rosinate to Ca（NO3）2, which should be controlled between 1∶1.2 to 1∶1.5.
