摘　　要：用色谱法对四氢呋喃等物质在溶剂１，４－丁二醇（ＢＤ）中的无限稀释活度系数进行了测定，采用同一柱温下固定液的流失量与实验测定的时间成正比的方法来推算固定液的流失，经过验证。The infinite dilution activity of tetrahydrofuran and other substances in solvent 1,4 butanediol were measured with chromatographic method.Correlation between the mass loss of stationary liquid and the experiment time was thought in direct proportion at constant temperature.Comparing the experimental and predicted results of the mass loss,the proposed correction method is suitable for this determination.

关 键 词：稀释活度系数 丁二醇 四氢呋喃 色谱分析
