摘要
采用气相色谱法快速分离检测环己酮及其中的杂质环己烷、苯和环己醇 ,分离时间为 3min,色谱柱为5% PEG 2 0 M/ Chromosorb,柱温 1 1 0℃ ,载气流速 35m L/ min。方法具有操作简便 ,分离效果和重现性好的特点 ,其分离度为 2 .38,相对标准偏差为 0 .1 %。
A method for simultaneous separation and detection of cyclohexanone as well as the impurities of cyclohexane benzene and cyclohexanol by gas chromatography was discussed. Determination of these analysis could be accomplished for 3 min by using 5%PEG20M/chromosorb column at 110 ℃ and the speed of carrier gas flow was 35 mL/min, resolution was 2.38 and relative standard deviation was 0.1%. This method had the advantages of easy operation, effective separation, good reproducibility.
