摘　　要：以苯膦酰二氯(PPD)和对苯二酚(HQ)为原料,合成了含磷阻燃剂2-(4-羟苯基)苯膦氧化物(BHPPO),并通过FT-IR、1 H NMR、13C NMR、ESI-MS对该化合物结构进行了表征。合成BHPPO的最佳工艺条件是在氮气保护条件下,n(PPD)∶n(HQ)=1∶2.4,反应物浓度为0.8mol/L,反应温度为130℃,反应时间为10h,其收率为91.73%;并通过热重分析研究了BHPPO的热稳定性能。A phosphorus-containing flame retardant bis(4-hydroxyphenyl)phenyl phosphine oxide(BHPPO)was synthesized by the reaction of phenyl phosphonic dichloride(PPD)and hydroquinone(HQ).The chemical structure of the obtained compound was identified by FT-IR,1 H NMR,13 C NMR and ESI-MS.The optimum reaction conditions were determined as follows:in nitrogen atmosphere,the mole ratio of phenyl phosphonic dichloride and hydroquinone was 1∶2.4,40 mL xylene as solvent,reaction temperature was 130℃,the reaction time was 10 h,yield was 91.73%.And the thermal stability of BHPPO was tested by MP and TG.
