随着我国合成纤维工业的迅速发展,对分散染料的要求,无论在数量上还是在品种上都有所增加。为此,就要求有一个快速、可靠、简便的分析方法,供鉴定分散染料之用,而薄层色谱具有价廉、快速、微量、灵敏及操作简便的优点。这一方法兼具柱色谱及纸色谱的优点,它的灵敏度比纸色谱高10～100倍,不仅可分析微量样品,而且可在研究染料的化学结构时,用作为制备色谱。分散染料跟其他种类的染料一样,往往是几种染料的混合物或是由于生产中带来的付染料;或是为了
With the rapid development of China’s synthetic fiber industry, the demand for disperse dyes has increased both in quantity and variety. For this reason, there is a need for a fast, reliable and simple analytical method for the identification of disperse dyes, which has the advantages of being inexpensive, fast, trace, sensitive and easy to operate. This method combines the advantages of column chromatography and paper chromatography. Its sensitivity is 10 to 100 times higher than that of paper chromatography. It can not only analyze trace amounts of samples, but also can be used for preparative chromatography when studying the chemical structure of dyes. Disperse dyes, like other kinds of dyes, are often mixtures of several dyes either due to the dye produced in production or
