【摘要】 报道了用高效液相色谱法测定对枯基苯酚合成液中对枯基苯酚的含量。用SpherisorbC18色谱柱 ( 2 5 0mm× 4 .6mm ,5 μm ) ,甲醇 /水 /醋酸 (体积比 90∶8∶2 )为流动相 ,流速 1.0mL/min ,检测波长 2 30nm。结果表明 ,对枯基苯酚进样量在 1.6～ 32 μg范围内线性关系良好 (r =0 .9995 ) ,平均回收率 98%～ 10 1% ,RSD不大于 1.2 %。该法操作简单 ,灵敏 ,准确 ,适合于对枯基苯酚生产过程控制分析和产品质量检测更多还原

【Abstract】 The HPLC system, consisted of Spherisorb C 18 column ( 250 mm × 4.6 mm, 5 μm ), methanol water acetic acid ( 90∶8∶2 ) mixture as mobile phase (flow rate 1.0 mL/min at room temperature) and with UV detection at 230 nm, was used to determine the content of paracumyl phenol. The linear range was sample injection 1.632 μg ( r = 0.999 5 ). The average recovery was 98%101%, RSD≤1.2%. This method is simple, sensitive and accurate. It could be used as the process and quality control means in paracumyl phenol production.更多还原
