摘　　要：用丙酮作为萃取剂,以正丁苯为内标物,采用萃取-气相色谱法测定顺丁橡胶中抗氧剂264含量。结果表明,萃取-气相色谱法操作简便、灵敏度高、分析速度快、精度高,测得的抗氧剂264含量相对偏差和相对标准偏差都小于2%,符合质量控制要求。The content of antioxidant 264 in the butadiene rubber was determined by using acetone extraction and gas chromatography with n-butylbenzene as the internal standard. This method was simple and fast, and had high sensitivity and high precision. The relative deviation and standard deviation of the test results were less than 2%, which met the quality control requirements
