On July 31, 2014, Vaz, Raquel V.; Magalhaes, Ana L.; Silva, Carlos M. published an article.Product Details of 321-28-8 The title of the article was Prediction of binary diffusion coefficients in supercritical CO2 with improved behavior near the critical point. And the article contained the following:
In this work, a predictive model for binary diffusivities at infinite dilution (D12) in SC-CO2 is proposed. It combines two terms – background and singular – with the objective to represent D12 accurately not only far but also near the critical point, where critical enhancement is always observed The model provides an average error of 6.20% for a large database including 149 systems and 4469 data points over wide ranges of temperature and pressure. The models selected for comparison (Wilke-Chang, Scheibel, Lusis-Ratcliff, Lai-Tan, Tyn-Calus and Reddy-Doraiswamy) achieve scattered and biased results, with average errors from 11.62-75.17%. In the whole, the new model exhibits an excellent performance for any kind of mols. in terms of size, mol. weight, polarity and sphericity, in all critical region. In order to help interested readers, a spreadsheet for the calculation of D12 is given in supplementary data. The input data is: temperature, pressure, CO2 viscosity, and solute properties (acentric factor, critical constants, molar volume at normal b.p., and mol. weight – given in this paper for the systems studied). The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Product Details of 321-28-8
