摘    要:本研究以八种二元羧酸为原料制得了其对应的单甲酯盐,并作为吸铬助剂应用于铬鞣,结果表明,戊二酸单甲酯钠具有较好的吸铬效果,铬鞣废液含铬量在0.5g/l以下以(Cr2O3计)。蓝坯革在复鞣加脂工段中,洗出的铬较少(为0.21g/l)。戊二酸单甲酯钠用于铬鞣不仅可促进铬在革内的均匀分布,而且可以解决二元酸盐用于铬鞣易导致粗面的缺点。

关 键 词:二羧酸单甲酯盐 制备 应用研究 铬鞣 含铬量 戊二酸单甲酯钠 皮革 吸铬助剂

Abstract:Eight kinds of dicarboxylic monomethylester salts are synthesized. Their application in chrome-tanning process shows that glutaric monomethylester sodium has good chrome-exhaustion ability, the chrome content in the waste tanning liquor is 0 491g/l(calculated on Cr 2O 3). In the retanning and fatliquoring processes, the total chrome content in the spent liquor is 0 21g/l. The distribution of chrome in leather is good and the grain is smooth.
Keywords:dicarboxylic monomethylester salt  chrome tanning  chrome content  glutaric monomethylester sodium
