1-萘磺酸和2-萘磺酸是用作生产染料、农药和药物的重要中间体,二者常以茶为原料经磺化而制得。用这种方法生产的萘磺酸常常是其各种异构体的混和物。而某些农药和药物的生产则需要高纯度的1-萘磺酸。为此需要有一精确、简单、快速而灵敏的检测此二萘磺酸的生产控制及其工艺产品的分析方法。
1 - naphthalene sulfonic acid and 2 - naphthalene sulfonic acid is used as an important intermediate for the production of dyes, pesticides and pharmaceuticals, both of which are often obtained by sulfonation of tea as a raw material. The naphthalenesulfonic acid produced by this method is often a mixture of its various isomers. Some pesticides and pharmaceuticals require 1-naphthalene sulfonic acid of high purity. For this purpose, an accurate, simple, rapid and sensitive method for the analysis of this naphthalenesulfonic acid production control and its process products is required.
