At this time, take boiling point reading and set inner scale opposite 0.0% alcohol on the "Degres Water Boiling Temperature vs Pressure in Vacuum Table Chart. This is because the boiling point does not depend directly on the temperature but pressure. This affects both the boiling point of water (if you test run it, a thermometer shows 100C in boiling water) and the boiling point of alcohol, for us the azeotrope of 95% alcohol and 5% water. The idea of ethyl alcohol as a liquid fuel is not new. Good Excuses For Losing Something, methanol boiling point under vacuum chart. Pentane has the straight structure of course. This is the answer. Methanol (CH3OH) is water-soluble and readily biodegradable, comprising four parts . The substance's melting point often varies with pressure and is defined at the normal pressure. This way the local ambient pressure becomes lesser than the actual value. The temperature ranges are given in the nist database and can be looked up easily. For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 C (173 F), whereas propane (MW 44) has a boiling point of 42 C (44 F).
