The isomers dostribution of ortho-and para-toluenesulfonamide are successfully determined by high performance liquidchromatography (HPLC) . The results are compared with ultraviolet-spectroscopy (UV).

本文采用高效液相色谱法(HPLC),成功地测定了邻、甲苯磺酰的异构体分布,并用紫外光谱法(UV)作的方法进行比较。

It was found that the sulphonamide group and the substituents on nitrogen atom within the molecule would effect the properties of these dyes.
