摘　　要：为了解决废旧皮革制品潜在的污染环境问题并使其资源化,采用正交实验的方法,利用水热反应釜通过加压水解研究了温度、时间、液固比、催化剂种类和用量对皮革水解率的影响。实验结果表明,温度、时间与催化剂都对水解率有较大影响。在最佳条件下,草酸催化废皮革水解率可达82%,Na OH催化废皮革水解率可达76%。In order to address potential environmental contamination of scrap leather stuffs and make those be useful resources, orthogonal experiments were conducted by using a hydrothermal reactor to investigate the effect of temperature, time, ratio of liquid to solid, catalysts and their amount, on hydrolysis yield of the leather. Experimental results show that the temperature, time and catalysts have substantial impact on the leather hydrolysis. Under optimal conditions, over 80 percent of the scrap leather can be hydrolyzed by oxalic acid catalysis and up to 76 percent of the scrap leather can be hydrolyzed by sodium hydroxide catalysis.
