使用薄层色谱可将商品木质素分散剂按分子量大小分离成数个清晰的组分,并证实了展开剂为正了醇:异丁醇:水=8:10:8.5时,70℃下活化的硅胶板分离效果最佳.该法不仅可用于实验室内分离木质素,还可作为工业生产的一种检测手段.
The commercial lignin dispersant was separated by TLC into several clear fractions using thin-layer chromatography and was confirmed to activate at 70 ° C with an alcohol: isobutanol: water = 8: 10: 8.5 Silica gel plate separation of the best.This method can not only be used for the separation of lignin in the laboratory, but also as a means of industrial testing.
