摘要
运用气相色谱-质谱联用技术和红外光谱法建立一种直接分析混合物体系纺丝油剂中酯类成分的方法。采用氢氧化钾-甲醇溶液酯交换法直接衍生纺丝油剂中的酯类化合物,通过气相色谱-质谱联用技术对其中的有机酸甲酯和交换出来的游离脂肪醇等进行快速定性分析,结合样品的红外光谱信息,快速鉴定混合物体系中酯类助剂成分。该方法操作简单、快捷,结合红外光谱结构特征性强的优势,适合混合物中特定目标物的结构分析。
A fast analysis method for qualitative analysis of ester components in finishing agent was established by GC/MS and FTIR without separating the mixture. The ester components from finishing agent were derived using KOH-CH3OH esterifying agent. The constituents and contents of the combined methyl ester of the organic acid and the fatty alcohol were analyzed by GC/MS. This results and the infrared spectroscopy information of ester components in finishing agent sample were used to determine the number and possible identity of the ester components on finish mixture. The method is rapid, simple and adapts to determine the given components in the mixture.
