Methanol is also an energy resource used in the marine, automotive, and electricity sectors and an emerging renewable energy resource. Whenever a liquid is heated, and this pressure balance takes place, it turns into vapor. While several types of distillation processes are in use, the one most commonly used in the biodiesel industry is vacuum distillation. This happens so because the pressure of surroundings get reduced significantly, at around 760mm of Hg the boiling point remains 78 degrees and at a vacuum of 100mm of Hg, the boiling point becomes 36 degrees. boiling point of ethanol under vacuum. Here, the loss of alcohol occurred because it has a higher vapor pressure than water, so some of it evaporated. . Now you can calculate its boiling point under any pressure.
