| Abstract: | The solubilities of ethylene glycol monomethyl ether and ethylene glycol monobutyl ether were measured at temperatures ranging from 313 to 363 K and pressures from 8.2 to 18.3 MPa in supercritical carbon dioxide.The solubility data were calculated and correlated using a semiempirical Bartle and Chrastil model,which showed satisfactory agreement with each other and the average absolute relative deviations were in the range of 8.88 %-16.72 % and 6.00 %-7.84 % respectively.According to the theory developed by ... |
