摘要
利用柱层析分离橡胶用复合抗氧剂,通过热重分析仪、傅里叶变换红外光谱、气相色谱-质谱联用、核磁共振氢谱、X射线荧光光谱和高效液相色谱等仪器分析其组分。结果表明,该复合抗氧剂由质量分数约68%的抗氧剂ODA、质量分数约21%的抗氧剂1520及质量分数约11%的烷烃油组成。
The compound antioxidant was separa ted by column chromatography, and the components were analyzed by thermo gravimetry analyzer, Fou rier transform infrared spectroscopy, gas chromatog raphy mass spectros copy, nuclear magnetic reso nance hydrogen spectrum, X-ray fluorescence spec troscopy and high performance liquid chromatogra phy. The results showed that the composite antioxidant was composed of antioxidant ODA with the mass fraction of about 68% , antioxidant 1 520 with mass fraction of about 21% and alkane oil with mass frac tion of ll%.
