用Taylor色散法测定了温度为308.15 ~ 328.15 K，压力为7.60 ~ 34.57 MPa时，2-丙酮、2-丁酮、2-戊酮和3-戊酮在二氧化碳中的无限稀释二元扩散系数。用时域拟合的方法从响应曲线中求得D12值。检查每次测量的拟合误差准确度。用施密特数相关法对测定的D_（12）数据进行了相关性分析，所有溶质的AAD%=3.74%。
Infinite-dilution binary diffusion coefficients of 2-propanone, 2-butanone, 2-pentanone, and 3-pentanone in carbon dioxide were measured by the Taylor dispersion method at temperatures from 308.15 to 328.15 K and pressures from 7.60 to 34.57 MPa. TheD12values were obtained from the response curves by the method of fitting in the time domain. The accuracy in the fitting error was examined for each measurement. The measuredD12data were found to be well correlated by the Schmidt number correlation, with AAD%=3.74% for all solutes.
