用GC MS和变温1 HNMR分析方法证明 ,在恶霉灵样品中存在互变异构现象 ,但这种互变异构现象受温度的影响不大 ,其主要的存在形式为烯醇式 ,2 0℃下烯醇式的含量为98.2 % .同时也证明了气相色谱用于该样品分析的可靠性 .
The results of GC MS and 1 H NMR analysis showed that there was tautomerism in the samples of hymexazol. However, this tautomerism was not affected by the temperature. The main existing forms were enol, 2 The enol content was 98.2% at 0 ° C. The reliability of gas chromatography for this sample analysis was also demonstrated.
