摘　　要：远古时期的油鞣、烟鞣已利用了醛与类醛鞣剂进行鞣制。醛基以亲电的形式与蛋白质氨基、亚氨基进行反应,使毛革与皮革获得保存稳定性与使用功能。结果表明,醛革能促进皮肤胶原蛋白的水热稳定性,并具有比铬革更好的耐水性和抗汗性。然而,醛鞣剂往往水合能力弱又缺乏足够的库仑吸引力,无法很好地渗透到皮肤胶原蛋白中,一些醛类物质具有生物毒性和颜色,制造成本高。本文综述了醛类化合物的结构和应用特点。根据已有的理论和实践,开发新型醛鞣剂和添加剂对替代铬鞣剂具有良好的前景和意义。Aldehyde and similar-to-aldehyde tanning agents were used in oil tanning and smoke tanning in ancient times.The aldehyde group reacts with the protein amino group in electrophilic form to obtain the preservation stability and practical function of fur and leather.The results show that aldehyde-tanned leather can promote hydrothermal stability of skin collagen and has better water and sweat resistance properties than chrome tanning.However,aldehyde tanning agents always lack sufficient coulombic attraction to penetrate well into skin collagen,and some aldehydes have biotoxicity and color,are not easy to dissolve and have high manufacturing costs.In this paper,the structure and application characteristics of some aldehydes were reviewed.According to prior theory and practice,the development of new aldehyde tanning agents and additives has good prospects and significance for providing substitutes for chrome tanning agents.
