The curve between the critical point and the triple point shows the methanol boiling point with changes in 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. This is because the boiling point does not depend directly on the temperature but pressure. Plastics Synthetics Unfortunately your pump cannot go that low. Usually, boiling points are published with respect to atmospheric pressure (101.325 kilopascals or 1 atm ). For a given pressure, different liquids boil at different temperatures. This calc can be extremely useful in designing experimental processes or making safety assessments.
