| 摘 要： | 以2,4-二叔丁基苯酚和自制的4,4'-联苯基双二氯化膦溶液为主要原料,在三乙胺的存在下制得亚磷酸酯型抗氧剂2,4-二叔丁基苯酚-4,4'-联苯基(P-EPQ)。实验表明:在一定的反应条件下,当三乙胺和4,4'-联苯基双二氯化膦的摩尔比为5∶1时,产品P-EPQ的收率达到最高值86%,纯度为99.7%。P-EPQ的受热分解温度高达350℃,因此它作为辅助抗氧剂,广泛应用于PP、ABS、PC等多种塑料材料的加工及应用中。

| Abstract: | The phosphite antioxidant Irgafos P-EPQ was synthesized using 2,4-di-tert-butylphenol and self-made 4, 4＇-biphenyl-bis-dichlorophosphine solvent as main raw materials in the presence of triethylamine. The experiment showed that the yield of Irgafos P-EPQ could reach 86% and the purity was 99. 7% when n（triethylamine）：n（4,4＇-biphenyl-bisdichlorophosphine） was 5：1 under certain reaction conditions. As a secondary antioxidant,Irgafos P-EPQ could be widely applied to various engineering plastics such as ABS ,PC and PA due to its decomposition temperature was up to 350℃. |
