Methanol, CH3-OH, is a colorless, fairly volatile liquid with a faintly sweet pungent odor, similar, but somewhat milder and sweeter than ethanol. In a closed container or system, this means that the amount of molecules transitioning from a liquid state into a gaseous state is the same number as those going reverting back into a liquid after being a gas. Flaming the liquid to burn off the alcohol still allowed for 75 percent retention. Downloads A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure.

The output temperature is given as C, F, K and R. Exposure to oxygen at these high temperatures can promote oxidation and prolonged heat exposure leads to thermal decomposition. However, distillation can't be used to fully separate the two chemicals. The boiling point of water is the temperature at which the vapor pressure of the liquid water equals the pressure surrounding the water and the water changes into a vapor. Below, figures and tables show the boiling point of water at varying vacuum. Different types of alcohol have different boiling points, so this can be used to separate them from each other and from other organic compounds. Unfortunately your pump cannot go that low. But if we'd like to be more precise, we should say that water boils at 100C when it's at atmospheric pressure.
