Dear bhaskar, Solvents with higher boiling points such as water (100 C at standard atmospheric pressure, 760 torr or 1 bar), dimethylformamide (DMF, 153 C at the same), or . 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. We use state-of-the-art diagnostic equipment to find the source of your heating and air conditioning problems and fix them fast. the distillation is very slow. Thus, the boiling point is dependent on the pressure. Vacuum distillation is the process of reducing pressure above the mixture that is to be distilled, slightly below the atmospheric pressure.
