摘要
用气相色谱与气相色谱／质谱来定性和定量分析由二甘醇制备的1，4－二氧六环和副产物。确定了1，4－二氧六环中所含的杂质，对共沸精馏法分离及提纯1，4－二氧六环有重要指导价值。
1, 4-dioxane and by-products from diethylene glycol were analysed qualitatively and quantitatively by GC and GC/MS. Impurities in the dioxane were determined. The analysis method has important directive value for separating and purifying 1, 4-dioxane with azeotropic rectification.
