Case Study

Solubility Study of Disperse Yellow 54 in Supercritical CO2

Tsai, Cheng-Chou, et al. Fluid Phase Equilibria, 2007, 260(2), 287-294.

Supercritical dyeing process has been considered as a potential green technology. The higher the solubility of the dye in the supercritical solvent, the higher the dyeing efficiency. This work measured the solubility of Disperse Yellow 54 in supercritical CO2 at different pressures, temperatures and with or without co-solvents.
Experimental methods and results
· The study focused on the solubility of disperse yellow 54 in supercritical carbon dioxide, using a semi-flow apparatus to investigate different contact times. A diffusion-controlled model accurately represented the experimental results, and an effective mass-transfer coefficient was determined by fitting extraction data to the model.
· Saturated solubilities of disperse yellow 54 in supercritical carbon dioxide were measured at temperatures between 353.2 K and 393.2 K and pressures up to 30 MPa.
· Solubility increased with pressure, and a crossover behavior was observed in a CO2 + disperse yellow 54 system.
· Cosolvents, such as ethanol and DMSO, were used to enhance solubility, with DMSO showing greater enhancement due to Kamlet-Taft solvatochromic parameters.
· The Chrastil equation effectively correlated solubility data within experimental uncertainty, and the Mendez-Santiago and Teja model showed consistency across all experiment conditions.
· The study highlighted the potential for using supercritical carbon dioxide as a solvent for disperse yellow 54, especially when combined with appropriate cosolvents to enhance solubility.

Study on the Dispersion Behavior of C.I. Disperse Yellow 54 in High-Temperature Dyeing

Chung, Yong-Sik, et al. Textile Research Journal, 2001, 71(2), 174-178.

The dispersion behavior of C.I. disperse yellow 54 (DY54) under dyeing conditions was evaluated by the turbidity ratio, which increases as the dye particle size decreases. The dispersion behaviors of two dye dispersions with different particle sizes during high-temperature dyeing were compared.
Dispersion behavior of C.I. disperse yellow 54
· Dye particles may grow at high temperatures. Dispersions with relatively small particles show an increase in dye particles due to crystal growth, but dispersions with large particles show less particle size variation in blank dyeing.
· In the actual dyeing process, the turbidity of large particles increases significantly at temperatures above 100°C and begins to decrease after cooling, but the turbidity of small particles decreases as dyeing proceeds.
· Dyes with small particle sizes initially show lower exhaustion values than those with large particle sizes, but eventually show higher values at temperatures above 130°C.
