Enter these data The boiling point becomes lesser as compared to the biling point at higher ambient pressures. While several types of distillation processes are in use, the one most commonly used in the biodiesel industry is vacuum distillation. At the time of these rapid oil price increases, m In the process of distillation, a liquid is carefully heated so more volatile compounds boil away. However if a liquid such as methanol was heated, and just enough vacuum applied to allow the methanol to vaporize, it could be condensed in a chiller type vessel before the vacuum pump. The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. Molecular weight: 32.042 kg/kmol.
