摘要
介绍了反相液相色谱法定量分析橡胶硫化促进剂二硫化硫醇基苯并噻唑的纯度分析方法。用 HP1100型高效液相色谱仪,ZORBAX RX-C18(250 mm×4.6 mm,5μm)色谱柱,流动相 V(甲醇):V(水)=3:1,λ=280 nm,流速1.0 mL/min,柱温25℃,对二硫化硫醇基苯并噻唑纯度进行定量测定。该法重复性好,相对标准偏差为0.11%,标准回收率在99.8%～100.2%,定量结果准确度高。
A reversed phase high performance liquid chromatography method for the determination of mercaptobenzothiazole disulfate（MBTS） purity was studied. A HP1100 liquid chromatography, equipped with a ZORBAX Stable Bond SB-C18 column and a UV detection（λ=280 nm） was used with 75 % methyl alcohol/25 % water as the mobile phase at flow rate 1.0 mL/min and column temperature （25±2） ℃. The average recovery was 99.8%- 100.2% with RSD 0.11% for MBTS.
