以环己酮为原料合成十二烷二酸二甲酯的气相色谱分析法

Gas chromatography method for dodecanedioic acid dimethyl ester synthesized by using cyciohexanone as raw material

以环己酮为原料合成十二烷二酸二甲酯粗品,含量测定采用气相色谱法:内标物选用癸二酸二甲酯,色谱柱选用大口径毛细柱FFAP(25m×0.53mm×1.0um)。结果表明:本方法具有简单、快速、准确、可靠。

this paper introduced the method of using Gas chromatography to determine the purity of crude dodecanedioic acid dimethyl ester （which is synthesized by using cyclohexanone as raw material）. Dimethyl sebactate is used as the internal standard marker, and FFAP（25m × 0.53mm × 1.0μm） type large caliber is used as the chromatography capillary . It is concluded that the method is simple, speedy, accurate and reliable.
