摘要： 为了探讨红曲红素在纺织印染加工业中应用的可行性，本文对红曲红素理化性能进行了研究。主要研究了红曲红素的溶解性、耐酸碱性、热稳定性和光稳定性，同时还研究了媒染剂对红曲红素的影响。结果表明：红曲红素能溶于水，在100℃以下相对稳定性，在pH=3~11范围内对酸、碱度稳定。红曲红素紫外稳定，对可见光敏感。媒染剂硫酸亚铁对红曲红素影响较小，重铬酸钾和硫酸铜对其有一定的破坏作用，氯化镨对红曲红素有护色作用，可使红曲红素染色牢度得到提高。

Abstract: The physical chemical properties of monascorubin were investigated in order to discuss the application feasibility of monascorubrin in dyeing and printing industry. The solubility, acid and alkali resistance, hot stability and light stability of monascorubin were researched. The effect of mordants on monascorubin was also investigated. The results showed that monascorubin could be dissolved in water. It was relatively stable under 100 ℃. In the range of pH 3~11, it was stable for pH values. Monascorubin maintained stable in the ultraviolet radiation, but sensitive to the visible light. Ferrous sulphate had little effect on monascorubin, while potassium dichromate and copper sulphate had disadvantageous effect on the pigment. Praseodymium chloride had the protection of color, which would improve the color fastness of monascorubin.
