Solubility of 4,4”-Methylene Diphenyl Diisocyanate at Temperatures Ranging from 313K to 353K in Supercritical Carbon Dioxide

摘要：

　　The solubilities of 4,4”-methylene diphenyl diisocyanate (MDI) in supercritical carbon dioxide were tested at temperatures from (313 to 353) K and pressures up to 16.3 MPa.The results indicated good solubility of MDI in supercritical CO2 at different temperatures and moderate pressures.To ascertain the tested solubility of MDI, two density-based correlations proposed by Bartle and Chrastil were studied.The results based on these two correlations showed good consistency between the experimental and calculated data,and values of average absolute relative deviation (AARD) computed with these two models were between (4.56 and 10.68) %, Bartle model,and 10.79 %, Chrastil model, respectively.
