超臨界流体の拡散と反応 クロマトグラフィックインパルス応答法による超臨界流体中における有機化合物の相互拡散係数の測定

Abstract

The chromatographic impulse response technique with the curve fitting method is a useful tool to measure binary diffusion coefficient under supercritical conditions. Based on our recent measurement data, the effectiveness of the simple predictive correlations such as the D12-viscosity correlation and the Schmidt number correlation is presented. Moreover, the sensitivities of the parameters determined and sources of experimental error are discussed.
