摘要：

An ethylene glycol (EG)-acetone (AC) system is studied via differential scanning calorimetry in the -140 to +40 degrees C range of temperatures. A phase diagram is plotted over the range of concentrations. It is found that the mixtures in the system are supercooled by more than 30 degrees C. Low-temperature melting is recorded in the region around -98 degrees C, which corresponds to the eutectic point temperature. The devitrification of rapidly cooled samples is observed in the range of concentrations up to similar to 21 mol % AC, and the temperature of devitrification is determined (T-g similar to -120 degrees C). The plotted phase diagram of the EG-AC system is compared to a water-acetone phase diagram.
