with more glycerol concentrations than were used in the rest of the work. Although the authors have no explanation for this abnormal solubility effect, they have enough supporting data to be convinced that it is real and not merely a consequence of experimental error.The tightness of the sleeve stoppers of the solution bottles was demonstrated by making Karl Fischer moisture determinations on four samples that had been immersed in the constant temperature bath for 46 days at 15°C. After deducting the dextrose, as determined with the saccharimeter, the water content of the solvent was found to be unchanged.
