摘要: 目的:建立测定2-乙烯基吡啶中对叔丁基邻苯二酚含量的高效液相色谱法。方法:采用十八烷基硅烷键合硅胶为填充剂,取十二烷基硫酸钠2.0 g,溶于10%(v/v)硫酸溶液15 mL,17 g·L-1四丁基硫酸氢铵35 mL和水650 mL的混合液中,用氢氧化钠试液调节pH值至3.3,然后与300 mL乙腈混合均匀,作为流动相;检测波长为280 nm,柱温为30 ℃,流速1 mL·min-1,进样量为10 μL。结果:溶剂不干扰测定,在0.204 6~4.092 μg·mL-1浓度范围内线性良好,重复性良好,检测限为0.170 μg·mL-1,定量限为0.512 μg·mL-1,低、中、高3个浓度的平均回收率为91.80%,RSD为2.4%。结论:该方法简便、准确、灵敏度高、重现性好,适用于2-乙烯基吡啶中对叔丁基邻苯二酚的检查。

Abstract: Objective:To establish a HPLC method for the determination of 4-tert-Butylcatechol in 2-Vinylpyridine. Methods: The 4-tert-Butylcatechol was separated on a base-deactivated end-capped octadecylsilyl silica gel chromatographic column. Dissolve 2.0 g of sodium dodecyl sulfate in a mixture of 15 mL of a 10 per sent V/V solution of sulfuric acid, 35 mL of a 17 g·L-1 solution of tetrabutylammonium hydrogen sulfate and 650 mL of water as the mobile phase, the spectrophotometer was 260 nm, the temperature of column was 30 ℃, the flow rate was 1 mL min-1, and the injection was 10 μL. Results: Determination was not interfered by the solvent. Over a concentration range of 0.204 6 μg·mL-1 to 4.092 μg·mL-1, it displayed a good linear relationship(R=0.999 5). The LOD and LOQ of 4-tert-Butylcatechol in 2-Vinylpyridine was 0.170 μg·mL-1 and 0.512 μg·mL-1 respectively. The average recovery rate of 4-tert-Butylcatechol was 91.80%(RSD=2.4%). Conclusion: The established method was specific, accurate and convenient, which can be used for the determination of 4-tert-Butylcatechol in 2-Vinylpyridine.
