Synthesis and application of universal dyes containing naphthalene ring;

含萘环通用染料的合成与应用研究

Recent Progress in Universal Dyes;

研究涉及新型染料分子结构的设计和合成,该染料分子具有在染浴之外不需进行其它的化学反应就对所有的纤维具有亲和力的特性,因此能在同一染浴中对不同结构类型的纤维进行染色,本文称该新型染料为通用染料。

A new universal dye containing two naphthalene rings was prepared by condensation of 7-aceta- mide-4-hydroxy-2-naphthalene sulfonyl chloride with N,N-dimethylethylenediamine, followed by the coupling reaction with ammonium of m-amino-benzene-β-hydroxyethylene sulfonate.

以7 -乙酰氨基 -4 -羟基 -2- 萘磺酰氯为原料,通过与N,N- 二甲基乙二胺缩合反应及与间氨基苯基- β -羟 乙基砜硫酸酯重氮盐的偶合反应合成了含双萘环结构的通用染料。

The absorbing moisture and moisture absorption rate of the konjac glucomannan acrylic acid copolymer(KAC) in different humidity and KAC of different particle size are investigated in this paper and the moisture absorbability of KAC and common desiccant(silica gel and mentor-rock) are compared in this paper.

研究了魔芋葡甘聚糖接枝丙烯酸共聚物(KAC)在几种环境湿度下的吸湿率和平均吸湿速率,分析了不同粒径KAC的扩散吸湿性能,并与变色硅胶、蒙脱石通用吸湿剂的吸湿性能进行了比较。
