摘要
采用自制β-环糊精衍生物填充柱气相色谱定量分析法,测定了合成糠醇粗产物中原料糠醛的残留量,在该方法条件下,糠醇和糠醛相对保留值为1.75,分离度为4.35.糠醛标准曲线线性相关系数γ=0.99994,此法用于纯品糠醛测定相对标准偏差为0.052%(n=5);用于样品中糠醛测定得变异系数值为1.84%(n=5);加标回收实验测定平均回收率分别为97.41%和101.66%(n=4).此法对糠醛的最小检知量为2.86μg.
Furfural in furfuryl alcohol gross production was determinated by GC of packed-column made up of β-cyclodextrain derivative. Furfuryl alcohol and furfural were well separated,the relative retention and resolution were respectively 1.75 and 4.35.The linear relation coefficient of standard curve was 0.999 94.The mean standard deviation of pure furfural was 0.052%(n=5).The coefficient of variation of furfural samples was 1.84%(n=5). The mean recoveries of two samples standard addition test were respectively 97...
