使用仪器型号为Agilent 6890N气相色谱仪，采用程序升温实现产物的分离，升温程序如下：初始温度 40 °C，保温时间 5 min，随后以 10 °C min-1 升温速率升温至 160 °C，保温时间 5 min。原料与产物的定量采用峰面积归一法。

The instrument model was Agilent 6890N gas chromatograph, and the product separation was achieved by programmed temperature rise, which was as follows: the initial temperature was 40 °C, the holding time was 5 min, and then the temperature was raised to 160 °C at the 10 °C min-1 heating rate, and the holding time was 5 min.  The quantitative method of raw materials and products was adopted by peak area normalization.
