【摘要】 本文作者使用紫外可见光谱测定仪，核磁共振波谱仪测定了乌洛托品铬铬合物的空间结构，认为在铬鞣条件下确实存在乌洛托品与六水合铬的铬合反应，从理论上解释了乌铬托品在铬鞣过程中具有隐匿，提高蓝湿革收缩温度、降低铬鞣废液含铬量等作用的原因。更多还原

【Abstract】 By means of UP and NMR, the author determinated the special structure of chrome-urotropinecomplex, and considered that the complexation reaction between urotropine and chromehexahydrate really exists in chrome tanning. Therefore it answerd the questions in theory that whyurotropine have the improving wetbluels shrinking-point and decreasing chrome content in tanneryeffluent更多还原
