摘　　要：以双醛和二乙醇胺为原料合成了新型复鞣剂GD-1,合成的最佳条件是:n(二乙醇胺)∶n(双醛)=2.2∶1,反应温度30℃,反应时间7h,反应体系pH值8。对复鞣剂GD-1的复鞣效果进行研究,结果表明,GD-1的最佳用量为2%(以铬鞣革质量为基准),染料吸收率提高,复鞣的铬鞣革无败色现象。A new retanning agent GD-1 was synthesized by dialdehyde and diethanolamine. The optimum parameters were that mole ratio of dialdehyde to diethanolamine 1：2.2, reaction temperature 30 ℃, reaction time 7 hours and pH 8. GD-1 was studied as a retanning agent for chrome tanning. The results showed that the optimum offer of GD-1 was 2% based on the weight of chrome tanned leather, the dye absorption rate was improved and the color intensity of retanned leather was not reduced.
