摘要
选用乙醇为提取剂,将日本和台湾的皮革色浆底料与溶剂分离,然后对含有色浆溶剂的乙醇溶液采用气相色谱,在PEG-20M色谱柱上进行了测定。结果表明,在色浆中主要含有二甲基甲酰胺(DMF)和甲苯,它们的含量分别为14.7％～32.7％和17.5％～31.00％。
The solvents and substrate in leather color pastes imported from Japan and Taiwan were separated by ethanol as extractant. Then,the ethanol solution were determined by gas chromatography in PEG-20M column. The results showed that the leather color paste from Japan and Taiwan contain N, N-dimethylformamide and toluene as solvents, their content is respectively 14. 7%～32. 7% and 17. 5%～31. 0%.
