摘要
以醋酸正丁酯为内标物,采用毛细管气相色谱内标法测定1,4-丁二醇及其酯化产物的含量。结果表明：1,4-丁二醇、1,4-丁二醇单醋酸酯、1,4-丁二醇双醋酸酯的相对校正因子曲线分别在0.7090~41.30mg·mL^-1、0.5980~41.82mg·mL^-1、0.5429~39.10mg·mL^-1范围内呈现良好的线性关系（R2≥0.9994）,平均加标回收率为94.53%~103.20%,RSD≤4.72%。该方法操作简便、精密度高、重现性好、结果稳定可靠,可用于1,4-丁二醇及其酯化产物的含量测定。
With n-butyl acetate as internal standard,the gas chromatography has been developed for the determination of 1,4-butanediol（0. 7090~41.30 mg·mL^-1 ）, 1,4-butanediol monoacetate（0. 5980~41.82 mg·mL^-1） and 1,4-diaeetoxybutane（0. 5429~39.10mg·mL^-1 ）. All linearity relative coefficients are higher than 0. 9994 within their respective ranges. And the average recoveries are from 94.53% to 103.20% with the RSD ≤4.72 %. This method is simple, accurate, reproducible, stable and reliable, which can be applied to the quantitative determination of 1,4-butanediol and its esterification products.
