Gas Chromatographic Analysis of 1,4-Cyclohexanedimethanol Cis-Trans Isomers
The separation of 1,4-cyclohexanedimethanol cis-trans isomers were carried out by gas chromatography with SE-54 column and CP-Chirasil-Dex CB column.The quantitative analysis of 1,4-cyclohexanedimethanol cis-trans isomers were carried out by SE-54 column and FID detector.The results showed that,for the trans isomer,the linear correlation coefficient was 0.9998,the relative standard deviation was 0.73%,and the average recovery was 100.00%.And for the cis isomer,the linear correlation coefficient was 0.9993,the relative standard deviation was 0.85%,and the average recovery was 100.56%.This method has the advantages of high separation accuracy,stable and reliable results,and simple operation for the quantitative analysis of 1,4-cyclohexanedimethanol cis trans isomers.
