Solubilities of disperse dyes of blue 79, red 153, and yellow 119 in supercritical carbon dioxide

Representing dyestuff solubility in supercritical carbon dioxide with several density-based correlations

“…It should be noted that all the collected data are assumed correct. The only exception is CI disperse blue 79 whose solubility in supercritical has been reported by three research groups [18][19][20]25]. These solubility data are demonstrated in Fig.…”

“…The Italian group recently re-examined the solubility behavior of blue 79 in supercritical CO 2 at 353.2-393.2 K and pressure varying from 180 to 300 bar [25]. Their result show that the CI disperse blue 79 solubility is considerably higher than that reported in the study of Lin et al [18], probably due to the fact that the authors have sufficiently collected the precipitated dyestuff inside the valve. In fact, the work of Lin et al shows that a 40 K change would not obviously affect the dye solubility, plausibly indicating their data for CI disperse blue 79 may not be accurate.…”

“…To date, there are rather a number of studies on dyestuff solubility behavior [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. A briefing of dyestuff solubility in supercritical CO 2 has been kindly updated by Lin et al [18,24]. They determined the equilibrium solubilities of disperse blue 79, red 153 and yellow 119, blue 79:1, red 82 and modified yellow 119 in the supercritical fluids at temperatures from 353.15 to 393.15 K and pressures up to 30 MPa.…”

Solubility of an acid dye in supercritical carbon dioxide by ion-pairing with dodecyltrimethylammonium bromide

“…Supercritical CO 2 are that it is inexpensive, non-toxic and non-flammable, it can be recycled and it has easily accessible critical conditions by giving an option avoiding water discharge. This new cleaner waterless dyeing technology appears to be economically attractive for the textile industry [1][2][3][4].…”

“…doi:10.1016/j.fluid.2006.08.014 measured the solubilities of five recently synthesized some 9-anthrone derivatives dyes in supercritical CO 2 using a simple and reliable static method at various temperatures and pressures. Lin et al [2] investigated three disperse dyes and they reported that the magnitudes of the solubilities are in the sequence of disperse blue 79 > disperse yellow 19 > disperse red 153 as pressure higher than 20 MPa. Gordillo et al [13] examined disperse blue 14 in supercritical CO 2 at various temperatures and pressures.…”
