| 摘 要： | DSD酸中所含的有机杂质大都源自氧化工序，其形成机理是氧化副反应的生成物和氧化反应的残余物．有机杂质主要是硝基物，混入产物DNS酸中，经还原后，生成氨基化合物，成为DSD酸中的有机杂质，对产品荧光增白剂的影响很大，如产品收率和强度、色光、白度等质量指标．提出了降低有机杂质的途径。

| Abstract: | It is described that most of the org, Impurities contained in DSD acid are derived from the oxidation stage, and their formation mechanism is the side-reaction of oxidation and the incomplete oxidation. Most of the org. impurities are nitro compds. They are mixed in DNS acid, turned to amino compds, in the reduction, and become the impurities of DSD acid, which result in important influences on the fluorescent whitener products, e.g., yield, strength, shade, whiteness etc. The ways to reduce their formation are also proposed. |
