摘要:
采用高效液相色谱法测定纤维素临氢水解反应产物,建立了定量分析的方法和回归方程。考察了不同流动相组成、流速、精密度和回收率对分析效果的影响。结果表明,较适宜的分析条件为流动相乙腈∶水为3∶1,流速为1 mL/min。在此分析条件下,纤维素临氢水解反应产物的峰面积与主要成分乙二醇、1,2-丙二醇和丙三醇标准品的线性关系良好,相关系数在0.99以上,精密度实验中乙二醇、1,2-丙二醇和丙三醇的RSD值在1.2%~1.9%之间,重复性实验乙二醇、1,2-丙二醇和丙三醇的RSD值在1.4%~1.6%之间,加标回收率实验的回收率在98.44%~102.55%之间,所建立的方法比较可靠。
Abstract:
A quantitative analysis method and regression equation were established for the determination of cellulose hydrohydrolysis products using high-performance liquid chromatography. The effects of different mobile phase compositions, flow rates, precision, and recovery rates on the analysis results were investigated. The results showed that the optimal analysis conditions were mobile phase acetonitrile 3∶1 in water, and a flow rate of 1 mL/min. Under these analytical conditions, the peak area of cellulose hydrohydrolysis products had a good linear relationship with the main components of ethylene glycol, 1,2-propylene glycol and propylene glycol standard products, and the correlation coefficient was above 0.99. The RSDS of ethylene glycol, 1,2-propylene glycol and propylene glycol in precision experiment were between 1.2%~1.9%. RSDS of ethylene glycol, 1,2-propylene glycol and glycerol were in the range of 1.4%~1.6%, and the recoveries of standardized tests were in the range of 98.44%~102.55%. The established method was more reliable.
