摘要:
利用气相色谱法直接测定生物质醇解液中产物乙酰丙酸乙酯.以正辛醇作为内标物,产物在FFAP毛细管拄中具有较好的分离效果,秸秆醇解液样品依时间稳定性较好,对秸秆醇解波产物进行了精密度和加标回收率的试验,平均相对标准偏差为0.617 5％,平均回收率为100.8％.结果显示该方法准确、迅速,重复性好.
Abstract:
In this paper, the gas chromatography has been used to measure ethyl levulinate in biomass alcohol-ysis products directly.Good separation was achieved from a FFAP column with n - octanol as internal stand-ard.Straw aleoholysis liquor samples have good stability with time changing. The precision and recovery testsfor the product were carried out. The average relative standard deviation is 0.6175% , and the average recov-ery is 100.8% . The results show that the method is accurate，fast and stable.
