Abstract

DEEP EUTECTIC SOLVENT (DES) WITH A FREEZING POINT OF UP TO 100 °C ARE FORMED BY THE REACTION OF PHOSPHONIUM AMMONIUM SALT OF FORMULA (I) R1 R2 R3 R4 Y+ X-, OR A HYDRATE THEREOF; WHERE Y IS P OR N, WITH FRUCTOSE A GLUCOSE CAPABLE OF FORMING A HYDROGEN BOND WITH X WHEREIN THE MOLAR RATIO OF I TO II IS FROM 2:1 TO 1:10 IN THE PRESENCE OF NOT MORE THAN 10 WT% OF WATER. ACCORDINGLY, THE DEEP EUTECTIC SOLVENT, WHEREIN THE DEEP EUTECTIC SOLVENT IS USED FOR RECOVERING FRUCTOSE AND/OR GLUCOSE FROM DATES, A METHOD COMPRISING THE STEPS OF: A) PROVIDING A MASS OF DATES AND DEEP EUTECTIC SOLVENT; B) SELECTING ONE OF THE DEEP EUTECTIC SOLVENT AND DISSOLVING THE DATES IN THE SELECTED DEEP EUTECTIC SOLVENT; C) VIGOROUSLY AGITATING THE SELECTED DEEP EUTECTIC SOLVENT AND DATES UNTIL A PRECIPITATE IS FORMED WITH A REMAINING SOLUTIONS; D) SEPARATING THE REMAINING PRECIPITATE AND THE REMAINING SOLUTION; AND REMOVING THE FRUCTOSE OR GLUCOSE FORM THE REMAINING SOLUTION; WHEREIN THE DEEP EUTECTIC SOLVENT IS SYNTHESIZED AT FREEZING POINT OF UP TO 100 °C BY THE REACTION OF PHOSPHONIUM OR AMMONIUM SALT WITH FRUCTOSE OR GLUCOSE IN THE PRESENCE OF NOT MORE THAN 10 WT% OF WATER.
