摘要利用气相色谱法测定了27种不同有机溶质的水-甲基异丁基酮分配系数。更新的亚伯拉罕模型相关性确定为描述溶质转移到甲基异丁基酮结合在本研究中测定的分配系数数据与发表的实验值取自化学和工程文献。一百十九个化合物被用于确定修订的亚伯拉罕模型相关性。计算后，发现修正的数学相关性与实验数据相匹配，总体平均标准偏差为0.21 log单位。
ABSTRACT Experimental water-to-methyl isobutyl ketone partition coefficients have been determined for 27 different organic solutes based on gas chromatographic measurements. Updated Abraham model correlations were determined for describing solute transfer into methyl isobutyl ketone by combining the measured partition coefficient data determined in the present study with published experimental values taken from chemical and engineering literature. One hundred nineteen compounds were used in determining the revised Abraham model correlations. After calculations, the revised mathematical correlations were found to match the experimental data to within an overall average standard deviation of 0.21 log units.
