Title: Process for the preparation of d-fructose
IPC: C13K11/00
Filed: 1962-11-09
Abstract: D-fructose is prepared by the isomerisation of D-glucose in aqueous solution using sodium or potassium aluminate as catalyst. Preferably the glucose solution is of 5-30% by weight concentration. Instead of pure D-glucose the starting solution may consist of crude starch hydrolysates or saccharose hydrolysates (invert sugar). In the latter case the amount of D-fructose formed by the isomerisation increases the amount already present from about 50% to about 80%. The preferred temperature range for the process is 25-38 DEG C.  After the isomerisation has taken place the aluminium is precipitated as hydroxide and filtered off. The D-fructose may be isolated in known manner as calcium fructosate which is treated with carbamic acid to release the D-fructose which is recrystallised from methanol.
