吲哚二甲川菁染料的绿色合成及其光谱研究

目的研究吲哚二甲川菁染料的绿色合成及部分染料的紫外-可见光谱性质。方法参照绿色化学的原则,采用微波辐照法,以哌啶为催化剂,在无溶剂条件下快速合成4种吲哚二甲川菁染料,并用1H NMR,IR,UV-vis确证产物的结构。结果提供了绿色合成吲哚二甲川菁染料的方法;所用无溶剂微波辐照法合成吲哚二甲川菁染料,既减少杂质的引入,又避免使用大量有机溶剂,反应条件温和,操作简便,后处理简单;合成的染料在不同溶剂中的最大吸收、摩尔消光系数有较大差别。结论染料的最大吸收波长基本随溶剂的折光率增大而红移;溶剂的折射率对于染料光谱吸收有一定影响。合成所需时间短、产率高,绿色环保。     

Sorption Behaviour of Acid Dyes by Soybean Protein/Poly （vinyl alcohol） Blend Fibre

The sorption behaviour of acid dyes by soybean protein/poly（vinyl alcohol） blend fibre was studied. The quantity of dye sorbed by the fibre increased markedly with the decrease in the pH of dyebath and reduced with the addition of neutral electrolyte when the pH was below 4.5, Acid dyes exhibited higher sorption rate constant and lower half dyeing time for the fibre than for spun silk and wool, which was related to the special morphological structure of the fibre, At pH 4, the sorption of disulphonated acid dyes with higher molecular weight followed the dual sorption mechanism of Langmuir plus Nernst-type partitioning well as they interacted with the fibre through electrostatic forces, hydrophobic forces and hydrogen bonds. It is considered that soybean protein and PVA components should be simultaneously dyed by disulphonated acid dyes with higher molecular weight.     

羊毛纤维吸附十二烷基磺酸钠的热力学研究

采用电导法研究了366K（93℃）时经洁净处理的羊毛纤维在酸性（PH=3．0～3．5）水溶液中对十二烷基磺酸钠（SDS）的吸附等温线，以及羊毛在不同助剂（含乙二醇／苯甲醇和硫酸锌）的水溶液中对SDS的吸附等温线．结果表明，加入助剂后，SDS的吸附量均出现不同程度的下降．可解释为较高温度下，阴离子表面活性剂SDS在水中的溶解度升高．同时，苯甲醇、乙二醇分子中都含有羟基，亲水性较强，在水中的溶解度也较高，使得表面活性剂与水的亲和性增强，表面活性剂分子自水中逃离而吸附于羊毛上的趋势相对减少，故SDS的吸附量降低．由通用吸附等温线公式估算了不同助剂作用下SDS在羊毛／溶液界面吸附的表面胶团聚集数和表面胶团化标准自由能，与实验结果比较符合．本文还研究了在空白浴和加助剂（“DL”、“FL”）条件下分散染料上染羊毛的吸附等温线，并探讨了其吸附机理，从较深层次上探索其染色机理．

Controlled-release Properties of Microencapsulated Disperse Dyes

Some disperse dyes were microencapsulated by means of in-situ polymerization. These microencapsulated disperse dyes was extracted respectively by ethanol under certain conditions. The controlled-release properties of disperse dyes through the shell of microcapsules were measured by spectrophotometer. According to the results, it was drawn that the type of disperse dyes, the auxiliaries contained in disperse dyes, the quantity of system controlling medium used and the core/shell ratio of microcapsules play important roles in controlling the release properties of microcapsules. The different controlled-release properties of microcapsules, which were prepared under given conditions, however, would in turn influence the performance of microcapsules in multiple-transfer printing.
