对于高级醇的分析方法,国内所见不多,而且多将其制成卤代烷,再还原成相应的高级烷烃,然后进行气相色谱分析。也有的将其乙酰化,转变成相应的酯,再进行气相色谱分析。上述二法均是将高沸点的烷醇转变成低沸点的化合物再进行测定,因此,都比较麻烦。 为适应三十烷醇工艺研究的需要,我们利用102G型气相色谱仪对Chromosorb型载体进行了选择,并对使用温度及其他分析条件和定量方法进行了多次的试验和探索,找到了一个适合于102G型气相色谱仪分析三十烷醇样品的分析条件和方法。柱温降至240℃,只要16分钟就能得到各组份谱图,而且分离效果好,柱流失少,使用近一年,进样500多次,柱效无明显变化。
For the analysis method of higher alcohols, there are not many domestic ones, and many of them are made into alkyl halides, and then reduced to the corresponding higher alkanes, followed by gas chromatographic analysis. Some of its acetylation, into the corresponding ester, and then analyzed by gas chromatography. These two methods are high boiling point alkanol into low boiling point compounds and then measured, therefore, are more troublesome. In order to meet the need of triacontanol technology research, we selected the Chromosorb type carrier by 102G gas chromatograph, and conducted many tests and explorations on using temperature and other analytical conditions and quantitative methods to find a suitable Analytical conditions and methods for analysis of triacontanol samples on a 102G gas chromatograph. Column temperature dropped to 240 ℃, as long as 16 minutes to get the spectrum of each component, and the separation effect is good, less column loss, the use of nearly a year, injection 500 times, column efficiency no significant change.
