摘要： 1,173,340. Fructose; addition compounds thereof. K. HARA, and T. BABA. 15 Feb., 1967 [16 Feb., 1966], No. 7217/67. Heading C2C. Fructose is separated from mixtures thereof with glucose and/or other mono- or di-saccharides by two processes, (A) when in an anhydrous mixture with glucose, by treating the mixture with anhydrous ethanol containing anhydrous CaCl 2 , the amount of ethanol being at least 5 times the estimated weight of fructose in the mixture and the amount of CaCl 2 being at least 60% by wt. the estimated amount of fructose, whereby an ethanol-soluble addition compound of fructose is formed and undissolved glucose is filtered off, or (B) when in an aqueous solution with other mono- or di-saccharides, by adding 15-100% by wt., based on estimated amount of fructose, of anhydrous CaCl 2 or SrCl 2 to the solution and then adding sufficient anhydrous or substantially anhydrous ethanol to the solution to bring the aqueous content thereof into the range 5-30% by vol., based on total volume of solvent, whereby the addition compound of fructose and CaCl 2 or SrCl 2 is precipitated, if necessary after seeding with crystals of the addition compound, recovering the addition compound by filtration, washing with 85% by vol. ethanol and drying. In process (B), ethanol can be replaced by an ethanol/ methanol mixture containing no more than 50% by vol. methanol. The fructose/CaCl 2 addition compound may be precipitated from the ethanol solution obtained by process (A) by adding sufficient water thereto to bring the aqueous content to 5-30% by vol., based on total volume. It is preferred to effect all the above processes at 10-25 C. Fructose may be liberated from the addition compound with CaCl 2 or SrCl 2 by dissolving the precipitates obtained by the above processes in an approximately equal amount by wt. of water and removing CaCl 2 or SrCl 2 by ion-exchange treatment or by adding an alkali metal sulphate to precipitate CaSO 4 or SrSO 4 and, after filtering, concentrating the aqueous fructose solution. Examples describe the separation of fructose from glucose and from invert sugar.
