以4,4'-二(氯甲基)联苯和2,3-丁二酮-亚磷酸三甲酯(1:1)加合物为原料合成了标题化合物,采用核磁共振谱、质谱、红外光谱和紫外可见光谱对化合物进行结构表征.在静态空气气氛中用热重-差示扫描量热分析法(TG-DSC)对其进行了热分析研究:168～436 ℃之间质量损失76.67%,最后的固体残留物为联苯骨架不完全燃烧的残留物.在272 ℃有一个放热峰,在210、302 ℃分别出现强吸热峰.结果表明该固态化合物在168 ℃以下很稳定.

In this paper, 3, 3'-(biphenyl-4, 4'-diyl) dipentane-2,4-dione was synthesized using4,4'-bis(chloromethyl)biphenyl and 2,2,2-trimethoxy-4,5-dimethyl-1,3,2-dioxaphospholene as starting materials. Its molecule structure was characterized by ~1HNMR,MS, IR and UV-Vis spectra. The thermal properties of 3, 3'-( biphenyl-4, 4'-diyl) dipentane-2, 4-dione were studied based on the TG-DTG and DSC-DDSC analyses in a static air at-mosphere. In a temperature range from 168 ℃ to 436 ℃, a mass loss of 76.67% was observed.The last solid residue was consid-ered generally as the remnants of biphenyl skeleton after incom-plete combustion. The maximum peak of heat release at 272 ℃ in DTG was resulted from exothermal decomposition reactions. The maximum peak of heat absorption at 210 ℃ and 302 ℃ in DSC was resulted from endothermic reactions, respectively. The test re-sults showed the compound had higher thermal stability at 168 ℃.
