环已胺釜残分析方法的技术改进

Technological development of analytical method for cyclohexylamine stillage residue

环己胺釜残分析一直使用的是传统的容量法分析。实验表明,色谱法分析环己胺釜残中环己胺、二环己胺含量与传统的容量法相对比,实验误差小,准确度高且即快速又节省试剂,能更好的指导生产。

Analysis for cyclohexylamine stillage residue is conventional volumetric method. Conclusion showed that Analysis the content of cyclohexylamine and dicyclohexylamine by chromatography is better than traditional method. Chromatography has lower aberration and higher accuracy. The method is rapid and it uses lower solvent. It can instruct production better.
