吡啶类暂溶性分散染料的合成研究

STUDY ON SYNTHESIS OF NEW DISPERSE DYES WITH PYRIDINIUM-ACETAMIDE

本文报导了一类新型暂溶性分散染料——吡啶阳离子染料的合成,采用IR、NMR,MS描述了这类染料的分子结构特征。实验表明,吡啶阳离子化反应在DMF中反应收率高,易于分离,为这类染料的工业化提供了可能。

The synthetic of new disperse dyes with pyridinium-acetamide is studied in this paper. The molecular structures of the dyes are described by NMR.IR.MS. The result of the experiment shows that in DMF yields of cationic reaction is high. Thus it is possible to produce the dyes industrially.
