利用CHP-20多孔树脂凝胶色谱(日产),分离提纯了带磺酸基的乙烯砜型活性染料及其水解物和醇解物。采用离子对反相高效液相色谱对这些化合物进行了分离分析。(一)样品的纯化合成的四个化合物见表1。采用快速层析柱对化合物Ⅰ、Ⅱ、Ⅲ进行分离提纯。填料为日本产CHP-20多孔树脂。
Using CHP-20 porous resin gel chromatography (Nissan), the sulfonic acid group-containing vinylsulfone reactive dyes and their hydrolyzate and alcoholysis products were separated and purified. These compounds were separated and analyzed by ion-pair reversed-phase high performance liquid chromatography. (A) The purification of the sample The four compounds synthesized in Table 1. Compounds I, II and III were separated and purified by flash chromatography. Filler for the Japanese-made CHP-20 porous resin.
