核磁共振谱法表征单偶氮染料结构

Environmental benign tannage technique

合成了系列单偶氮染料 ,测定了其 1H- NMR谱、13 C- NMR谱及二维核磁 2 D- NMR方法表征的 H,H- COSY氢氢相关谱、H,C-氢碳相关 HMQC谱、H,C- HMBC氢碳远程相关谱 ,并研究了其偶氮 -醌腙互变异构平衡。

Three conventional techniques for environmental benign tannage which are using auxiliary agents of chrome, less chrome and without chrome tannage are described. The key of environmental benign tannage techniques is considering leather producing as important as environment protecting.
