复隆黑（Foron Black）RD-3G 300％的结构剖析

Structure Analysis of Foron Black RD-3G 300 %

用薄板层析对复隆黑（Foron Black） RD-3G 300％进行展开,表明它是一种有四个染料混合而成的复合染料,它包括蓝色、紫色、橙色和红色组分.该混合物的各组分,是用20 cm×10 cm的硅胶板以及用环已烷∶乙醚（1∶1）混合溶液为展开剂予以层析分离,再用括刀括下各个组分,用许多这样的硅胶板分离,以获得足够量用于分析各个组分染料,用氯仿萃取,以获得各个组分的纯染料,分别用薄板层析、有机元素微量分析、红外光谱、核磁共振以及质谱等方法予以分析.

The Foron Black RD,3G 300 % was separated and purified by thin layer chromatograph（TLC）. This dye is verified to be mixture dye which consist of blue, violet, orange and red components. The individual Structure of the components was dissected by IR, NMR, mass spectra（MS）, and organic element microanalysis. The verification of structure has been obtained by comparing of IR, TLC synthetic compounds and Blue, Violet, orange and Red components. The chemical structure has been confirmed by synthesis.
