Study of the phase diagram water fraction of the system water-glycine-sucrose by DTA and X-ray diffraction methods

The system water-glycine-sucrose was studied at temperatures below 0°C by DTA and X-ray diffraction methods. The hexagonal ice and β-glycine formations were detected, but other crystal phases were not. Eight isopleths crossing the angles of water and glycine were studied. The water fraction of the plane phase diagram, involving a monovariant line of the secondary crystallization water + glycine and eight isotherms, was plotted.
