摘　　要：首先合成出稳定的铝—己二胺络合物,以它为预鞣剂进行少铬鞣制。实验中主要以坯革的收缩温度和废液含铬量作为考察指标。在本实验范围内,用这种络合物预鞣可使铬鞣时铬盐的用量下降到0.5％(以Cr_2O_3计),废液中铬含量大大降低,坯革的质量较好,有利于减轻制革厂的铬污染。In this study, the stable complex of aluminium-Sulphate and hexanediamine, used as a pretanning agent in the process of less chrome tannage, is synthesized at first. The Shrinkage Temperature(Ts) of the wet-blue leather and the amount of chrome in exhausted solution are main object to be examined. In this test, when the pretanning agent is used in the process, only 0. 5% chrome oxide (based on the pickled skin weight) is added, the amount of chrome in exhausted solution reduced greatly and the chrome pollution decreased considerably.
