In this work, the Perturbed Hard Sphere Chain (PHSC) equation of state (EoS) has been utilized to model the solubility of sugars in pure and mixed solvents.In this regard, thirteen sugars containing glucose, fructose, xylose, maltose, mannitol, mannose, sorbitol, xylitol, galactose, erythritol, maltitol, trehalose, and sucrose have been considered.The model parameters have been optimized using a binary sugar-water equilibrium data at an arbitrary temperatureThe solubilities of sugars in water and alcs. at various temperatures have been predicted using the obtained model parameters.The average AAD% value of sugar solubility in pure solvents has been obtained 0.98%.The model was also applied to predict the solubility of sugars in mixed solvents without using addnl. adjustable parameters.The results show that the PHSC EoS can predict the solubility of sugars in mixed solvents up to high concentrations accurately.The average AAD% value of the ternary sugar-water-alc. system has been obtained 6.5%.The results show that the PHSC EoS can be used as a robust thermodn. model to predict the solubilities of sugars in mixed solvents up to high concentrations and various temperatures accurately.
