Water at high pressure has a higher boiling point than when that water is at atmospheric pressure. Namely that methanol has a vapour pressure of 1 atm precisely at this temperature - the liquid boils, and pushes back the atmospheric pressure, and bubbles of vapour form directly in the liquid. In the process of distillation, a liquid is carefully heated so more volatile compounds boil away. However, at low temperature and/or very high pressures it becomes a solid. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the surrounding environmental pressure. The boiling point of ethanol is 79*C and under vacuum (28 inHg) it drops to around 34*C.
