  • Method for separating fructose and glucose
    Patent number: 7942972
    Abstract: A process for separating fructose and glucose from mixtures of fructose and glucose from a liquid phase feed solution or a solid mixture containing the fructose and glucose is disclosed. The process implements ionic liquids as selective solvents that dissolve fructose and glucose in large quantities, but at different proportions which are then separated by filtration into a precipitate and a solution of ionic liquid enriched with the other sugar. The process also involves separation of the sugars from the ionic liquid enriched with the other sugar which is accomplished by one of various processes such as extraction with water in a centrifuge or cooling to reduce the solubility of sugar and then filtration. The ionic liquid is then recycled.
