摘 要

分散染料中偶氮类占一半以上,与其他结构分散染料相比,偶氮型分散染料因为原料易得,合成工艺比较简单,色谱齐全,染料色泽鲜艳,发色强度高等优点日益受到重视并且产量仍在不断增加。在偶氮分散染料中有一类染料以杂环化合物作为重氮组分或者偶合组分,因为杂环化合物的存在,此类染料具有鲜艳的色泽、高的发色强度、耐碱性较好、能在较宽的pH值范围内应用、而且各项牢度优良,近年来,成为企业开发和研究的重点。吡唑类化合物是具有广泛应用的重要氮杂环化合物，具有非常广泛的应用领域和研究价值。

本论文根据染料化工企业生产实际和市场需要，采用3-氨基-5硝基苯并异噻唑为重氮组分以3-甲基-1-苯基-2-吡唑啉-5-酮为偶合组分合成1只偶氮分散染料。合成的染料采用紫外-可见吸收光谱，红外光谱，质谱等分析测试手段验证所合成的化合物的结构。

Studies on the Synthesis, Characterization of Nitrobenzopsendothiazole Pyrazolone Derivatives Dyes

ABSTRACT

Azo disperse dyes occupies more than half. Compared with other structures, the raw materials of azo-based disperse dyes are easy to obtain. The synthetic process of them is simple and the color shade is bright and strong. So they are paid more and more attention and their production continues to increase. In azo disperse dyes, there are some dyes containing heterocyclic compounds as the diazo component or coupling component. Because of the existence of heterocyclic compound, these dyes generally have brighter color and luster, higher strength of color, and the fastness is good. They also can be appled to a wide pH range (4-12). In recent years, more attention has been paid on the development of heterocyclic-aromatic amine disperse dyes, in which heterocyclic compounds being diazo group. There are very important pyrazole compounds with five yuan heterocyclic, which is widely used in various fields as their value of the research and application of very extensive.

To meet the needs of market and production of enterprises, in this paper, 3-amino-5-nitro-(2,1)-benzisothiazole as diazo components, and I choose 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one as coupling component, a azo disperse dye was synthesized by diazotization and coupling reaction. Their structures were confirmed by ultraviolet-visible spectra, infrared spectra and mass spectrometry.

Keywords: Disperse dyes,heterocyclic reagents, azo disperse dyes,pyrazole compounds

1．1 分散染料概述

1．1．1 分散染料的定义与分类

分散染料是一种不带水溶性基团的染料,在应用过程中以分散态存在于水溶液中对纤维进行染色,它是非离子型染料,在水中呈分散状离子形式存在。分散染料商品有粉状、浆状、液状和颗粒状等形式,目前仍以粉状居多^[1]。

分散染料有两种分类方法,一是按染料的应用性能分类;二是按染料的分子结构分类。

按染料的应用性能分类是根据染料对温度的敏感性程度不同分类,最常用分散染料分为三种:
