DSD酸系列中间体下游产品的开发应用及展望(Ⅱ)

Development,usage and prospect of downstream products of DSD Acid's intermediates

DSD酸及合成DSD酸过程中的中间过渡产物NTS酸、DNS酸和DNS酸单还原的产物ANSD酸,这四种化合物统称DSD酸系列中间体,它们是重要的有机化工原料。本文全面系统地介绍了DSD酸系列中间体下游产品的开发应用现状,它们可用于荧光增白剂、直接染料、酸性染料和活性染料的合成,本文介绍了它们的合成原理,列出了主要品种的化学结构式、C.I.索引号、CAS登记号、国内外主要商品名称,展望了发展前景。

DSD Acid,NTS, DNS and ANSD are called DSD Acid＇s intermediates which are important raw materials of organic chemicals. The article fully introduces the current situation of development and usage of downstream products of DSD Acid＇s intermediates which are OBA, Direct Dyes,Acid Dyes, and Active Dyes. The article briefly introduces the synthesis principle,chemical structures, C. I. Nos, CAS Nos and Chinese name, English name of the main downstream products. It also gives the development prospect of these products.
