Summary

To characterize the rate of ice nucleation as a function of temperature (to -150 deg C), the solutions were cooled at a constant rate to the nadir temperature and then warmed to a storage temperature at which ice formation was studied under isothermal conditions. Cryomicroscopic measurements of the spherulite concentration confirmed the appearance of two nucleation events in ethylene glycol solutions. Differential scanning calorimetry studies showed that the total amount of nucleation increased approximately 20-fold if the concentration of ethylene glycol was decreased from 51 to 48 wt%. The proportion of nucleation attributable to each of the nucleation events are studied in relation to the ethylene-glycol concentration.
