| 摘 要： | 在聚氨酯生产中,环氧丙烷中醛类物质含量直接影响聚醚质量,需要严格检查、控制。醛类物质的测定,目前国内外一般采用色谱法或比色法。也有用Hg~(2+)盐安培滴定法测定芳香醛。用2,4-二硝基苯肼直流极谱法测定醛,用原子吸收法测定低分子量醛和酮。我们根据间苯二酚与丙醛在果糖和浓盐酸作用下生成红色醌式产物的特性,较详细地研究了间苯二酚光度法测定环氧丙烷中微量丙醛的最佳条件和干扰因素。结果表明,本法灵敏度高、稳定性好,应用范围广。

| Abstract: | This paper is researching optimum condition and interfering factor of the sperctrophotome-tric determination of micro propylaldehyde in the epoxy propane with resorcin. The new methodof analysis is proposed. The result shows is that the sensitivity of the method is higher and thestability is better. The limit of detection is 0.24 ppm. |
