建立了用气相色谱法测定二甘醇醚化产物中二甘醇单丁醚、二甘醇单乙醚、二甘醇单甲醚的分析方法。通过对不同配比的固定液及柱温等操作条件的比较，选择了合适的分析操作条件。用校正面积归一法，测定各组份的含量，相对误差＜２％。
A method was established for the determination of diethylene glycol monobutyl ether, diethylene glycol monoethyl ether and diethylene glycol monomethyl ether in the diethylene glycol etherification product by gas chromatography. By comparing different operating conditions such as fixed solution and column temperature, the suitable operating conditions were selected. Calibration area normalization method, the determination of the content of each component, the relative error <2%.
