Zirconyl chloride upon hydrolysis in water to form Zr(OH) Ο© has been found to react to form a fluorescent derivative with not only a ketose such as fructose but also a hexose such as glucose and the disaccharide sucrose. When reaction conditions such as a temperature of 99Β°C and a time of 60 min are

hydrogens. These changes were attributed to increase in basic strength and hydrogen-bonding ability on methylation.
The pH of the amide solution did have some effect upon the particular amide solution's tendency to damage human blood cells. The low pH of the DEF solutions appears to be the reason for the total destruction of cells at very low amide concentrations. When buffered to a near-neutral pH, the critical concentration was raised from 0.4 to 10% (Table 11). With the other amide solvents, there was little change in the critical concentration by the addition of an isotonic phosphate buffer since none of these amide solutions had inherently high or low pH values.

## Abstract This work comprises the implementation of a methodology for the study of an industrial crystallization process by freezing and cooling to be applied in the separation of sugars with industrial relevance (glucose and fructose). The main interest is the production of fructose. This sugar
Saccharornyces cerevisiae ATCC 39859 was immobilized onto small cubes of wood to produce ethanol and very enriched fructose syrup from glucoselfructose mixtures through the selective fermentation of glucose. A maximum ethanol productivity of 21.9 g 11. h was attained from a feed containing 9.7% (w/v
