咪唑类固色剂的合成研究

文档编号:CL035  文档字数:10013,页数:20

摘　要:固色剂是能提高染色和印花织物染色牢度的物质，随着人们对纺织品的要求越来越高，我们急需开发和应用符合环保要求和环保指标的绿色固色剂。
以乙二醛为原料，在甲醛中与硫酸铵在85～90℃反应得产物，用熔点仪测产物的熔点，确定其产物为咪唑。再与环氧氯丙烷在25～30℃之间反应1～2h，溶液透明，有一定粘度后，再升温至70～80℃，继续反应5h，得到的产物中加入乙二胺，最后得淡紫色固色剂，进一步对固色剂的应用工艺性能进行了探讨,经测试固色后的织物的干摩擦牢度为4级，湿摩擦牢度为3级及耐水洗牢度效果一般,但这实验设计合成简单，成本便宜，适用于实际生产。表明这一实验设计具有一定的研究价值，需要我们的进一步探索。

Abstract: Fixing agent is able to improve the fastness of dyed and printed fabrics material, as people increasingly high demand for textile products, we need development and application of environmental compliance and environmental indicators of the green fixing agent. With glyoxal as raw material, formaldehyde and ammonium sulfate at 85 ~ 90 ℃ by the reaction product of the product by melting point melting point measuring instrument to determine their product is imidazole. Then with the reaction between epichlorohydrin in the 25～30℃ 1～2h, the solution transparent, have a certain viscosity, then heating to 70～80℃, continued to be 5h, the product obtained by adding ethylene diamine, and finally get lavender fixing agent, fixing agent for further application of the process performance is discussed, tested fabric after fixing the dry rubbing fastness is 4, the wet rubbing fastness and washing fastness of 3, the general effect, but this experiment Design and Synthesis of simple, low cost, suitable for actual production. Suggest that this experimental design has some research value, we need further exploration.
