稀土与氨基苯磺酸、氨基萘酚磺酸作用产物的研究

为探讨稀土在皮革染色过程中的助染作用，本文通过红外光谱及差热分析，对稀土与染料的模拟物———氨基苯磺酸及氨基萘酚磺酸的作用产物进行了分析，结果表明，稀土离子与染料分子中的—ＯＨ、—ＳＯ－３ 都能发生结合。

Study of Interactants between RE and Aminobenzenesulfonic and Aminonaphtholsulfonic Acids

The interactant between RE and model materials of dyestuff namely aminobenzenesulfonic and aminona~phthol~sulfonic acids were discussed with the help of IR and DTA analysis with the purpose of investigating the effects and mechan~ism of RE in the dyeing process of leather. Experimental results showed that RE can combine with -SO - 3 and -OH groups of dyestuff.
