吡啶类暂溶性分散染料热反应及应用研究

STUDY ON MOLECULAR STRUCTURES OF PYRIDINIUM-ACETAMIDE TYPE DISPERSE DYES AND THEIR DYEING PROPERTIES

本文研究了新型暂溶性分散染料——吡啶(钅翁)阳离子染料的应用性能。利用TG—DTA讨论了吡啶热反应并研究了吡啶正离子对相邻碳原子化学位移的影响。实验表明,这类染料可用于聚酯纤维的染色。

The application properties of new disperse dyes with pyridinium-acetamide are stuied in this paper, the reacti-vity of pyridinium-acetamide is described by TG-DTA. Influ-encc of chemical shift of a-carbon with cationic group on the carbon-13 NMR spectra is discussed. The result of the experi-mcnt shows that the dyes can be applied to dyeing polyester fiber.
