摘　　要：本文根据《铬鞣液组成的研究（Ⅰ）、（Ⅱ）、（Ⅲ）、（Ⅳ）》的研究结果［１～４］，分析对比了碱度为０％、碱度３３％硫酸铬、氯化铬、硝酸铬鞣液的组成和糖还原碱度为０％、碱度３３％的硫酸铬、氯化铬、硝酸铬和高氯酸铬鞣液的组成；分析对比了碱度３３％的硫酸铬鞣液和糖还原碱度３３％的硫酸铬鞣液的组成。根据大量的分析对比弄清了不同铬鞣液组成的变化规律和铬鞣液组成与鞣革性能之间的关系；本研究结果对鞣剂改性和研制开发新型鞣剂提供了理论依据。Abstract According to the research results of `the compositions of chrome tanning liquors(Ⅰ)(Ⅱ)(Ⅲ)(Ⅳ)' ,we have compared the compositions of 0% and 33% basic Cr 2(SO 4) 3,CrCl 3,Cr(NO 3) 3 tanning liquors,the compositions of glucose reduced 0% and 33% basic Cr 2(SO 4) 3,CrCl 3,Cr(NO 3) 3,Cr(ClO 4) 3 tanning liquos,and the compositions of 33% basic Cr 2(SO 4) 3 tanning liquor and glucose reduced 33% basic Cr 2(SO 4) 3 tanning liquor.On the basis of a great quantity of analyses and comparisons,we have found the changeable rules of the compositions of different chrome tanning liquors and the relation between the compositions of chrome tanning liquors and their tanning properties.This research results provide theoretical basis for the research of new tanning agents.4 refs
