Type of article: Article
Summary
Aqueous solutions of ascorbic acid have been shown, using differential scanning calorimetry (DSC), to form glassy states during freezing. Alternating DSC, as a new technique, further helped to study five thermal events observed during heating of frozen ascorbic acid solutions to complete melting from below the temperature for maximal freeze concentration of ascorbic acid in water depends somewhat on heating rate and was found to be -54 deg C for 10 deg C/minute.
