(2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanal → D-(-)-Fructose

Participants

Reaction Steps

Two series of four glucose-containing liquor samples (mother liquor from primary dextrose crystallization, 90DE) were prepared containing 0.005M magnesium chloride and 0.001M cobalt chloride. Series A contained 53.4 percent dry substance, and Series B contained 56.7 percent dry substance. To the samples, were added various quantities of the air-dried filter cake of example I and sulfite salts. The isomerizations were carried out at 70° C. for various times under an atmosphere of nitrogen. The color and fructose formed during the isomerization reactions were determined and are shown below in table III.
