【摘要】 用色质联用技术对尼龙酸二甲酯进行了组成分析,对尼龙酸二甲酯中的丁二酸二甲酯、戊二酸二甲酯和己二酸二甲酯组分的气相色谱—质谱离子流图进行了解析.三种组分的主要特征碎片离子峰进行了归属,其中丁二酸二甲酯出现分子离子峰(弱),戊二酸二甲酯和己二酸二甲酯组分未出现分子离子峰.更多还原

【Abstract】 The compositions of dimethylester nylon acids were determined by gas chromatographymass spectrometry(GC-MS) technology.The GC-MS ion current chromatograms of dimethyl succinate, dimethyl glutarate and dimethyl adipate components existed in dimethylester nylon acids were analyzed. The main characteristic fragment ion peaks of these three components were assigned,in which the molecular ion peak(weak) of dimethyl succinate was observed,but the molecular ion peaks of dimethyl glutarate and dimethyl adipate components were not observed.更多还原
