Solubility of six different carbohydrates in methanol, ethanol, 1‐propanol, and 2‐propanol were measured at 22, 30, and 40°C. Ketose sugars (fructose, tagatose, and lactulose) show higher solubilities than aldoses (glucose, galactose, and lactose). The binary solid–liquid equilibrium data obtained was satisfactory represented by using the A‐UNIFAC model. Additionally, the capability of the model to predict the carbohydrate solubility in alcohol–alcohol and alcohol–water mixed solvents was explored. © 2007 American Institute of Chemical Engineers AIChE J, 2007
